Aconstant net torque is applied to an object. which one of the following will not be constant?
a) angular accelerationb) angular velocityc) moment of inertiad) center of gravity

B) Angular velocity

Explanation:

The equivalent of Newton's second law for rotational motions is

where

is the net torque on a system

I is the moment of inertia

is the angular acceleration

From the formula, we observe that if a constant net torque (=different from zero) is applied to an object, than the angular acceleration of the object is non-zero and constant.

But angular acceleration is defined as the rate of change of the angular velocity, :

so, a non-zero angular acceleration means that the angular velocity is changing, so the correct answer is B.
