ROTATIONAL MOTION

What is the rotational analog of force in linear motion?

• Energy
• Power
• Torque
• Impulse

What is the effect on moment of inertia if the mass is doubled while keeping shape and size constant?

• It quadruples
• It halves
• It doubles
• No effect

Which has a greater moment of inertia: a solid disc or a hollow ring of the same mass and radius?

• Solid disc
• Both are equal
• Hollow ring
• Depends on thickness

For which object is the moment of inertia independent of its radius?

• Circular disc
• Thin ring
• Hollow cylinder
• Thin rod about center

What primarily 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
