• Motion, in physics, change with time of the position or orientation of a body. Motion along a line or a curve is called translation. ... In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).

Answer 2

Answer:

Motion, in physics, change with time of the position or orientation of a body. Motion that changes the orientation of a body is called rotation. In both cases all points in the body have the same velocity (directed speed) and the same acceleration (time rate of change of velocity).Kinetic energy, form of energy that an object or a particle has by reason of its motion. If work, which transfers energy, is done on an object by applying a net force, the object speeds up and thereby gains kinetic energy.Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.As we can say, objects moving with different rate will take different amount of time to cover a given distance. Hence, one of the ways of measuring the rate of motion of an object is to find out the distance travelled by the object in unit time. This quantity is defined as speed.The "direction of motion" is basically the direction of the object's displacement during a very small time interval.The radial component of the acceleration is related to the change in direction of the velocity vector and points along the radius of curvature.
