ROTATIONAL MOTION

How is the moment of inertia analogous to mass?

• Both are forces
• Both resist changes in motion
• Both are velocities
• Both are energies

What is the main assumption about angular velocity in rigid body rotation?

• It varies with mass
• It is zero
• It is the same for all particles
• It depends on temperature

What is the condition for rotational equilibrium in the ladder?

• F1 = F
• N = W
• Sum of moments about any point is zero
• F2 = 0

How does the moment of inertia affect rotational motion?

• No effect
• Higher I means easier to rotate
• Higher I means harder to rotate
• Depends on ω

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

• It is linear kinetic energy
• It is potential energy
• It is torque equation
• It is the rotational kinetic energy formula
