ROTATIONAL MOTION

What does the equality of angles α1, α2, α3 indicate?

• The body is accelerating
• The mass is increasing
• No rotation is occurring
• The body is shrinking

In combined motion, why do points O and P have different velocities?

• Because P is heavier
• Because O is stationary
• Because P has additional rotational velocity
• Because friction slows O

What is the condition for a body to undergo pure translational motion?

• Different accelerations
• Variable orientation
• All particles move with identical velocities
• Changing mass

How does the text suggest students simulate different types of motion?

• By watching animations
• By solving equations
• By using a liquid
• By using a rigid object like a heavy book

What is common to all particles in a rigid body undergoing rotation about a fixed axis?

• Same linear velocity
• Same kinetic energy
• Same momentum
• They share the same angular velocity
