Question

A body moving in circular motion with constant speed has :

• A. constant velocity
• B. constant acceleration
• C. constant kinetic energy
• D. constant displacement

Answer 1

Answer: (C)

constant kinetic energy

A body moving along a circular path moves such that it traverses equal arc-length in equal intervals of time. Displacement, velocity and acceleration changes at each point on the trajectory.Hence, the speed is uniform and consequently the kinetic energy is also constant throughout.
