A nonzero net torque is described as causing changes in an object's:
ARotational motion
BChemical makeup
CElectric charge
DOptical colour
Answer & Solution
Correct answer: A. Rotational motion
1. Torque is to rotation what force is to straight-line motion.
2. Forces acting on an object can cause torques.
3. A nonzero net torque causes changes in the rotational motion of an object.
4. It also changes the object's angular momentum.
