Question

A body moving along the circumference of a circle with uniform speed is accelerated. why? What is the angle between the velocity vector and acceleration vector in uniform circular motion?

Answer 1

because the direction of motion is changing and therefore velocity is changing and hence body is accelerated.Since the speed is constant, there is no tangential acc. but there is centripital acceleration which is always directed towards centre of circular path and hence angle between velocity vector and acceleration vector is 90 degrees

In uniform circular motion, total acceleration of an object in a circular path is equal to the radial acceleration.
