A body moving in a circular path with a constant speed has constant (a) momentum (b) velocity (c) acceleration (d) kinetic energy

Answer: (d). Momentum, velocity and acceleration are vectors whose direction keeps changing. Speed is constant, so KE = 1/2mv² is constant. So the answer is (d) kinetic energy.

Centripetal Acceleration & Force

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

Show answer and solution

Answer: (d)

Momentum, velocity and acceleration are vectors whose direction keeps changing.
Speed is constant, so $KE = \frac{1}{2}mv^2$ is constant.
So the answer is (d) kinetic energy.
