ROTATIONAL MOTION

What happens to the moment of inertia if the axis of rotation is shifted farther from the center of mass?

• It decreases
• It remains unchanged
• It becomes zero
• It increases

In rotational motion, what is the analogue of force in linear motion?

• Mass
• Velocity
• Momentum
• Torque

What is the role of angular velocity in the kinetic energy of rotation?

• It has no role
• It only affects direction
• It determines the speed of rotation and affects energy quadratically
• It reduces moment of inertia

If two bodies have the same mass but different shapes, can they have different moments of inertia?

• No, mass is the only factor
• Only if densities differ
• Yes, because I depends on mass distribution
• Only in vacuum

What is the significance of the equation K = ½ Iω²?

• It calculates torque
• It determines angular momentum
• It is the formula for rotational kinetic energy
• It finds the center of mass
