Question

Is uniform circular motion is accelerated ? Give reason.

Answer 1

A uniform circular motion is anaccelerated motion. Give reason. ...Uniform circular motion is acceleratedbecause the velocity changes due to continuous change in the direction ofmotion. So, even when the body moves ta a constant speed, its velocity is not constant.

pls mark this as brainlist

Answer 2

Yes, uniform circular motion is an accelerated motion. In this motion the object moves in a circular path with a constant speed. But during its course of motion the direction of the object changes at every instant. Which implies a change in velocity at every instant of its motion. Whenever there is a change in velocity with respect to time there is acceleration. The centripetal force keeps the body in its circular track. The acceleration of the body due to this force is the centripetal acceleration. It is directed along the radius and towards the center of the circular path.
