There is a net net torque that is applied to a rigid object. What happens?
a. the angular momentum of the object will change
b. the kinetic energy of the object will change
c. the object will experience an angular acceleration
d. the rotational inertia of the object will change
e. a., b., and c.
I say c, am i close
a) is the correct answer.
c) is not necessarily correct because the torque can be at right angles to the angular moemntum, causing only the direction of the angular momentum vector to change and not its magnitude.
