Textbook Problem

A constant net torque is applied to an object. Which one of the following will not be constant? (a) angular acceleration, (b) angular velocity, (c) moment of inertia, or (d) center of gravity.

To determine
The type of screwdriver required to turn a screw.

Explanation

The torque is given by,

τ=Iα

  • I is the moment of inertia.
  • α is the angular acceleration.

Conclusion:

Constant net torque implies constant angular acceleration. Hence, the angular velocity changes with time at a constantly. Therefore, option (b) is correct
