Q.A body moving in a circular path with a constant speed has a

  • AConstant acceleration
  • BConstant velocity
  • CConstant kinetic energy
  • DConstant displacement
Correct Answer : (C)

Constant kinetic energy

Hints :

A body moving in a circular path with a constant speed has a Constant kinetic energy. When a body is moving in a circular motion with constant speed, the direction of it continuously changes and hence velocity(v), momentum(p), and acceleration change because they are vectors and their direction changes. only as kinetic energy is a scalar, it remains constant.
