Question

Anathlete is moving along a circular path with constant speed .is the motion uniform or accelerated? give reason

Answer 1

While moving along circular par, the direction of motion is changing at every instant means velocity is changing, it is given that athlete is running with same speed means it is moving with constant acceleration.

Answer 2

An athlete moving in a circular path will have an accelerated motion.

EXPLANATION:

This is because when the athlete moves in a circular path, the body will have centrifugal and a centripetal force acting on it and when a force acts on a body, the motion of a body is accelerated.  

When the athlete moves in a circular path with the same speed, the velocity changes with the direction, thereby making the motion accelerated motion.
