ROTATIONAL MOTION

Can a body be in translational equilibrium but not in rotational equilibrium?

• No
• Yes
• Only in space
• Only at rest

Can a body be in rotational equilibrium but not in translational equilibrium?

• No
• Yes
• Only in liquids
• Only in gases

What happens to the total angular momentum if external torque is zero?

• It increases
• It decreases
• It becomes zero
• It remains constant

What is the effect of doubling the angular velocity on rotational kinetic energy?

• It doubles the energy
• It halves the energy
• It quadruples the energy
• It has no effect

How does angular momentum relate to linear momentum?

• It is unrelated
• It is the same as linear momentum
• It is the rotational analog of linear momentum
• It is the inverse of linear momentum
