** One of the common examples of uniformly accelerated motion is freely falling bodies**. The only acceleration which is acting on the body is g (acceleration due to gravity). If we are taking the vertically upward direction as the positive, the acceleration due to gravity (g) will be negative since it is in the downward direction Uniformly accelerated motion, or constant acceleration, is motion that has a constant and unchanging velocity. Uniformly accelerated motion may or may not include a difference in an object's speed. The acceleration of an object means that there is a net force in the direction of that object's acceleration

- Q.8 Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force? Explain it with an example. Sol. A body in uniform circular motion is an example of accelerated motion. Consider the motion of earth around the sun
- Yes it is possible. Let us take an example, circular motion. In this it has acceleration and constant velocity along tangential. Hence it is possible
- Yes, it is possible for a body to accelerate, without changing the speed. Bodies in circular motion are continuously accelerating. Even if they don't change their speed, their velocity is constantly changing due to continuous change in direction of motion. Can a body have constant speed and still have uniform acceleration
- What is meant by accelerated motion? A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing. Is acceleration possible in uniform motion? An object undergoing uniform circular motion does not.

Is it possible that an object is in the state of accelerated motion due to. Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force. Explain it with an exampl * What are the possible states of motion for the object pictured in the diagram, given the fact that the two forces acting on it are equal and opposite in direction? a*. the object must be moving at a constant velocity since there are some forces on it. b. the object cannot be moving since the forces are equal and opposite

State with reasons, if it is possible or impossible, for an object in motion to have : (a) Zero distance covered and may have non zero displacement. (b) Zero speed at an instant but non zero acceleration at the same time. (c) Zero speed and may have non zero velocity. (d) Acceleration opposite to the direction of motion Acceleration has to do with changing how fast an object is moving. If an object is not changing its velocity, then the object is not accelerating. The data at the right are representative of a northward-moving accelerating object. The velocity is changing over the course of time (b) The given statement is possible. The object can move in a certain path with a perpendicular acceleration, in the case of circular motion. When an object is moving along a circular motion its path is along the circle tangent but the centripetal acceleration is towards the circle radius

- Uniform
**accelerated****motion**simply means that an**object****is**increasing its speed in a uniform manner, that is at the same rate per unit time. The horizontal dimension, is a nice sounding phrase that simply describes a plane in Euclidean geometry, which is perpendicular to the vertical dimension, another nice sounding phrase - From the third equation of motion, v 2 = u 2 + 2as v 2 - u 2 = 2as It is clear that the work done is equal to the change in the kinetic energy of an object. Question 18: Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force? Explain it with an example.
- an object in motion will remain in straight motion unless acted upon by another force. Is the object accelerated horizontally? Explain. No. The forces add to zero, so the first law applies. Is it possible that the object pictured in question 8 is moving, given the fact that the two forces acting on it are equal in size but opposite in.
- If an object is under constant acceleration and moves on the x-axis plane, it is known as a uniform accelerated motion on the horizontal plane or dimension. Similarly, if the movement is along the y-axis, it would be known as a vertical uniformly accelerated motion
- The velocity-time graph of an object is shown in the fig: (a) State the kind of motion that object has, from A to B and B to C. (b) Identify the part of the graph where the object has zero acceleration. Give reasons for your answer. (c) Identify the part of the graph where the object has negative acceleration. Give reasons for your answer
- Yes it is absolutely possible to have acceleration in uniform motion. A uniform circular motion is an example of such a situation, where in the speed or magnitude of velocity remains same but due to changing directions, the acceleration changes. READ: Why does Felix call Dimitri boar? What changes continuously in uniform circular motion

An object moving with constant speed can be accelerated if its direction of motion changes. For example, an object moving with a constant speed in a circular path has an acceleration because its direction of motion changes continuously. Question 5. Two trains A and B start moving at the same time We can change the state of motion of an object by changing its speed, its direction of motion, or both. Acceleration is the rate at which the velocity is changing. 4.4 Acceleration . 4 Linear Motion In physics, the term acceleration applies to decreases as well as increases in speed An object's state of motion is defined by how fast it is moving and in what direction. Speed and direction of motion information (when combined, velocity information) is what defines an object's state of motion. Newton's laws of motion explain how forces - balanced and unbalanced - effect (or don't effect) an object's state of motion * When the object moves in a circular path with uniform speed, it means that its magnitude of velocity does not change, only its direction changes continuously*. Hence, it is considered as uniformly accelerated motion. Question 6 Differentiate between a uniform linear motion and a uniform circular motion. Solution

24 C. Freefall An object is in freefall when its motion is only acted upon by gravity with constant acceleration along y-axis equal to the acceleration due to gravity. Examples of objects in free fall (in one dimension) include objects that are falling, objects dropped from rest, objects thrown downward, and objects thrown upward Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force Explain with a example - Science - Work and Energ State which of the following situations are possible and give an example for each of these: (a) An object with a constant acceleration but with zero velocity.(b) An object moving in a certain direction with an acceleration in the perpendicular direction Therefore, circular motion is an example of an object moving with an acceleration but with uniform speed. Uniform circular motion. A circular motion is described as a body movement that follows a circular path. Uniform Circular Motion is the motion of a body travelling at a constant speed along a circular path Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force. Explain it with an example. (NCERT Question Bank, CBSE 2012) Answer: When an object has uniform circular motion, the speed of the object remains the same i.e. v = u. Hence, work done by the force = zero

Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force. Explain it with an example. Answer * Is it possible to have an accelerated motion with a constant speed? Name such type of motion*. A. Yes, Uniform Circular Motion. B. Yes, Non-Uniform Circular Motion. C.

No. State whether the following statements are true or false by writing T'F against them An object moving on a circle at constant speed is an example of accelerated motion. If it were possible to move the Earth so that its new orbit was twice as large as it is now, then the length of a year (in terms of the number of days) would also double. What property summarizes a body's tendency to stay in the state of rest or motion.

- In which of the following cases is the motion accelerated and which is it not accelerated? 1. A rock falling freely for 2 m. 2. A meteoroid (a rock in outer space) that is so far from all planets and stars that gravity is negligible. 3. An artificial satellite orbiting Earth at a steady 30,000 km/hr. 4. The moon. 5
- How is uniform circular motion regarded as an accelerated motion. Give an example of such a motion. Ques: State the action and reaction in the following : (a) moving rocket (b) firing of a bullet from a gun (c) a person walking on the floor. Ques: (a) Define momentum of a body. (b) A ball is thrown vertically upward
- It is possible for an object to have acceleration opposite to the direction of motion If a body motion is slowing down then the acceleration is in same direction but the change in the velocity in opposite direction to that of the motion of the body. Example is Paddling a bicycle and when u apply break
- In classical mechanics, Newton's laws of motion are three laws that describe the relationship between the motion of an object and the forces acting on it. The first law states that an object either remains at rest or continues to move at a constant velocity, unless it is acted upon by an external force. The second law states that the rate of change of momentum of an object is directly.
- Acceleration is a measure of the change in the velocity of an object per unit time and mathematically it is given as. If the velocity of an object changes from an initial value u to the final value v in time t, the acceleration a is given by, a = v−u t a = v − u t. and this kind of motion is called accelerated motion

Acceleration is a vector quantity just like velocity. Also acceleration is dependant on velocity as [math]a=dv/dt[/math]. So if velocity can be made zero the acceleration will also become zero.Oh wait this is possible!Just make the body move in a.. Is it possible that an object is in the state of accelerated motion due to external force acting on it, but no work is being done by the force ? asked Feb 7, 2018 in Class IX Science by navnit40 ( -4,938 points **State** with reasons, if it is **possible** or impossible, for an **object** **in** **motion** to have : (a) Zero distance covered and may have non zero displacement. (b) Zero speed at an instant but non zero acceleration at the same time. (c) Zero speed and may have non zero velocity. (d) Acceleration opposite to the direction of **motion** It is uniformly accelerated to velocity, v in time, t by the application of a constant force, F throughout the time t. The initial and final momentum of the object will be, p1 = mu and p2 = mv respectively. The change in momentum = p2 - p1. The change in momentum = mv - mu. The change in momentum = m × (v - u) A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing. For all other kinds of motion, both effects contribute to the acceleration. When runners change from a jog to a sprint, they are accelerating.

Newton's Laws of Motion . Select the best possible answer. will the object be accelerated? a. The acceleration is zero because the net force is zero. b. The object moves in the direction of force F 1 with an acceleration a = F 1 /m. c. The tendency of objects to resist a change in motion is called: a. Friction * All the other answers appear to be incorrect*. If anything is falling with only the force of gravity acting on it it is in free fall. Nothing on the surface of the earth - rotating with the earth - would be in free fall since all objects are acted.

If an object in motion has a velocity in the positive direction with respect to a chosen origin and it acquires a constant negative acceleration, the object eventually comes to a rest and reverses direction. If we wait long enough, the object passes through the origin going in the opposite direction. This is illustrated in Figure Lakhmir Singh Solutions Class 9 Physics Chapter 1 Motion. Motion is defined as the movement of an object from one place to another. When an object moves along a straight line, the motion is known as rectilinear motion. Distance, displacement, uniform motion, non-uniform motion, speed, acceleration and velocity are the terms that are used for. When the object moves in a circular path with uniform speed, it means that its magnitude of velocity does not change, only its direction changes continuously. Hence, it is considered as uniformly accelerated motion

This means that the object does not cover the equal distance in equal time intervals. If the motion is not consistent in the case of rectilinear motion, the acceleration of the body will be non-zero. For example, the motion of a vehicle, an oscillation of a pendulum. Non-uniform motion is also called accelerated motion Newton's Laws of Motion Newton's First Law of Motion Objects at rest stay at rest, Objects in motion stay in motion, Until something changes its motion. Things continue doing what they are doing unless a force is applied to it. Objects have a natural tendency to resist change. This is INERTIA Since the object is in free fall, we have to make a few assumptions. First, we need to assume the acceleration of the rock is -9.8 m/s^2 due to the force of gravity. Next, since the rock was. The object is accelerated in one direction and the boat is accelerated in the opposite direction. In this case, both the motion of the object is visible and the motion of the boat in the opposite direction is also visible. Explore the resulting motion of two interacting objects as a result of Newton's Third Law in this Pirate Ship simulation.

Textbook solution for Glencoe Physics: Principles and Problems, Student 1st Edition Paul W. Zitzewitz Chapter 2 Problem 74A. We have step-by-step solutions for your textbooks written by Bartleby experts The object is only shortened in the direction of motion. Therefore, a long, slender rocket ship would NOT become a smaller version of itself, but rather, would become a short, stubby rocket ship. At some point in history, the length contraction was known as the Fitzgerald contraction and physicists have been known to quote an applicable limerick Experiment 3 Uniform and Accelerated Motion I NTRODUCTION The objectives of this experiment is to introduce the concepts of distance, displacement, velocity, and acceleration for straight-line motion and to use graphing techniques to analyze the relationships between these concepts. Briefly explain and give examples of the difference between distance traveled and displacement, speed and velocity Actually, it is possible in circular where speed remains constant but since the direction is changing hence the velocity changes, and the body is said to be accelerated. Average acceleration The average acceleration over a period of time is defined as the total change in velocity in the given interval divided by the total time taken for the change

State whether distance is a scalar or a vector quantity. Solution : Give one example of a motion where an object does not change its speed but its direction of motion changes continuously.

A uniform linear motion is unaccelerated, while a uniform circular motion is an accelerated motion. d Constant velocity is a vector. A vector is a quantity that requires both a magnitude and direction to fully describe the quantity. For velocity, the magnitude refers to how fast the object is. (c) in accelerated motion (d) moving with uniform velocity Answer: (c) In merry-go-round, the speed is constant but velocity is not constant, because its direction goes on changing i.e., there is acceleration in the motion. So, we can say that the boy is in accelerated motion. Question 7

Force and Laws of Motion Class 9 Extra Questions Long Answer Questions. Question 1. Describe Newton's first law of motion in detail, giving examples.

Is it possible for the object to be travelling with a non-zero velocity? If yes, state the conditions that must be placed on the magnitude and direction of the velocity. If no provide a reason. Answer: According to Newton's 1st law of motion, no net force is required to move an object which is moving with a constant velocity An object of mass 1 kg travelling in a straight line with a velocity of 10 ms -1 collides with, and sticks to, a stationary wooden block of mass 5 kg then, they both move off together in the same straight line. Calculate the total momentum just before the impact and just after the impact. Also calculate the velocity of the combined object The data regarding the motion of two different objects P and Q is given in the following table. Examine them carefully and state whether the motion of the objects is uniform or non-uniform. Answer: We can see that the object P covers a distance of 10 m in every fifteen minutes. In other words, it covers equal distance in equal interval of time The unstructured overset method shown in Horne and Mahesh [1] and Horne and Mahesh [2] was found capable of scaling to O (10 5) computational cores for O (10 5) moving bodies in turbulent flow fields while producing accurate flow results. This highly scalable method is modified and extended to effectively utilize on-node hardware acceleration

An aspect of this property is the tendency of objects to keep moving in a straight line at a constant speed, when no forces act upon them.. Inertia comes from the Latin word, iners, meaning idle, sluggish.. Inertia is one of the primary. Motion of an object that is not accelerated (moving at a constant speed and in a straight line) can be found using the formula. d= v t. d is the distance traveled; v is the rate of motion (velocity) t is the time; Some sample problems that illustrates the first and second laws of motion are shown below: Example

The speed is 20 m/s, and the direction is downward. Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing When can you say that the motion of the body is uniformly accelerated motion? And thus, it seems, we shall not be far wrong if we put the increment of speed as proportional to the increment of time; hence the definition of motion which we are about to discuss may be stated as follows: A motion is said to be uniformly accelerated, when starting from rest, it acquires, during equal time-intervals An object that falls through a vacuum is subjected to only one external force, the gravitational force, expressed as the weight of the object. An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton's second law of motion. With algebra we can solve for the acceleration of a free falling object Yes this could be possible. In uniform circular motion body is executing circular motion with constant speed but still it is having centripetal acceleration

We can change the **state** **of** **motion** **of** **an** **object** by changing its speed, its direction of **motion**, or both. Acceleration is the rate at which the velocity is changing. 4.4 Acceleration . 4 Linear **Motion** **In** physics, the term acceleration applies to decreases as well as increases in speed Naturally Accelerated Motion. Having established experimentally that heavy objects fall at practically the same rate, Galileo went on to consider the central question about speed of fall barely touched on by Aristotle---how does the speed vary during the fall?The problem is that it's very difficult to answer this question by just watching something fall---it's all over too fast But an object's acceleration is the same, as measured from any frame with uniform motion. In that sense, non-uniform motion is *physically significant*, so we base dynamics on it.:: If you equate motion to velocity, acceleration is not motion. Even a *change* in some quantity is not the same thing as the original quantity (deficit is not debt)

equilibrium: The state of a body at rest or in uniform motion, the resultant of all forces on which is zero. An object with constant velocity has zero acceleration. A motionless object still has constant (zero) velocity, so motionless objects also have zero acceleration Maybe it's an alien spacecraft. Scientists have been puzzling over 'Oumuamua ever since the mysterious space object was observed tumbling past the sun in late 2017. Given its high speed and its. Momentum Principle (basically Newton's second law) Newton's second law says: Where F net is the total force an object, m is the mass and a the acceleration. Procedure. The way to test this theory is to apply a force to an object and measure its acceleration. You already know how to measure the acceleration - using the sonic ranger and making.

The Newton's three laws of motion are Law of Inertia, Law of Mass and Acceleration, and the Third Law of Motion. John Ray Cuevas. Newton's First Law of Motion. A body at rest persists in its state of rest, and a body in motion remains in constant motion along a straight line unless acted upon by an external force. 1 Chapter 5 - Force and Motion I I. Newton's first law: If no net force acts on a body, then the body's velocity cannot change; the body cannot accelerate v = constant in magnitude and direction. - Principle of superposition: when two or more forces act on a body, the net force can be obtained by adding the individual forces vectorially Newton's First Law of Motion An object will continue in its state of rest or motion in a straight line provided no external force acts on it Basically, this means that if for instance a ball is lying on the ground, it will stay there. If you kick it into the air, it will keep moving. If there was no gravity, it would go on for ever The reason is simply because it is a wave. Other quantum objects such as the electron do have mass, and they have no problem being created at some non-zero speed without ever needing to be accelerated to this speed. All quantum objects are partly waves and therefore can have a speed the moment they are created The principle of equivalence, in Einstein's recounting, is supposed now to eliminate the distinctive status of inertial motion. For it is supposed to be extending the relativity of motion from inertial motion to accelerated motion. However inertial and accelerated motions remain distinguishable absolutely

In classical physics and special relativity, an inertial frame of reference is a frame of reference that is not undergoing acceleration.In an inertial frame of reference, a physical object with zero net force acting on it moves with a constant velocity (which might be zero)—or, equivalently, it is a frame of reference in which Newton's first law of motion holds Chapter 9. The Kinetic of Rotation: In Chapter 4, the kinetic of straight line motion was discussed where ΣF = Ma was the kinetic equation. ΣF was the net force or the cause of motion, M or mass was treated as a measure of resistance toward straight line motion, and a the acceleration caused by ΣF.. Here, in Chapter 9, the kinetic of rotation will be studied where ΣT = Iα is the kinetic. During the 14th century, the French scholar Nicole Oresme studied the mathematical properties of uniformly accelerated motion. He had little interest in whether that kind of motion could be observed in the realm of actual human existence, but he did discover that, if a particle is uniformly accelerated, its speed increases in direct proportion to time, and the distance it traverses is.
