A constant net torque is exerted on an object. Which of the following quantities for the object cannot be constant? (Select all that apply.)

A. kinetic energy
B. angular velocity
C. angular acceleration
D. moment of inertia
E. angular position

A. kinetic energy

B. angular velocity

E. angular position

Explanation:

The quantities that cannot be constant if a constant net torque is exerted on an objecta are:

A. Kinetic energy. If a torque is applied, the linear or angular speed will be changing at a rate proportional to the torque, so the kinetic energy will change too.

B. Angular velocity. It will change at a rate equal to the torque.

C. Angular position. If the angular velocity changes, the angular position will change.
