Question

A body moving along a circular path will have :

• A. a constant speed
• B. a constant velocity
• C. no tangential velocity
• D. a radial acceleration

Answer 1

The correct option is D a radial acceleration

Velocity is not constant since the direction of the ball changes every instance.
The ball has radial acceleration since there is a centripetal force acting on it towards the center.
Ball moving in a circular path has tangential velocity. Cutting the thread , the ball moves tangentially
