ROTATIONAL MOTION

What determines the moment of inertia of a body?

• Only total mass
• Only shape
• Mass and its distribution relative to the axis
• Only distance from center

How is rotational kinetic energy expressed in terms of moment of inertia?

• I ω
• ½ I ω
• ½ I ω²
• I ω²

What is the rotational analog of linear momentum?

• Torque
• Kinetic energy
• Force
• Angular momentum

Can the perpendicular axis theorem be applied to a solid sphere?

• Yes, always
• Only if symmetric
• No, because it is not a planar body
• Yes, in special cases

Which theorem relates moments of inertia about perpendicular axes in a plane?

• Parallel axis theorem
• Work-energy theorem
• Perpendicular axis theorem
• Pythagorean theorem
