Question

Uniform circular motion in an example of acceleration motion? Explain statement?

Answer 1

Uniform circular motion is accelerated because the velocity changes due to continuous change in the direction of motion. So, even when the body moves ta a constant speed, its velocity is not constant. Thus, for a body moving in a circular path at a constant speed, its velocity changes continuously. The change in velocity gives rise to an acceleration in the moving body. Therefore circular motion is an acceleration motion even when the speed remains constant.

Answer 2

Answer:

When a particle moves along a circular path, its direction changes every moment. The speed of the.particles may change or remain constant. If the speed of the particle moving in a circle is same, it is.said to be in uniform circular motion. Since the direction of the particle is changing every moment, its velocity is continuously changing. Thus, the motion of the body along circular path is an example of accelerated motion. This acceleration acts towards the centre of the circle and hence, called centripetal or radial acceleration.
