ROTATIONAL MOTION

What is the role of the center of mass in translational motion?

• It remains stationary
• It rotates independently
• It disappears
• It follows the translational trajectory

In rotational motion, what path do particles of a rigid body follow?

• Straight lines
• Random curves
• Circular paths around the axis
• Parabolic paths

What is the motion of a top spinning in place?

• Pure translation
• Linear motion
• Vibration
• Rotation about a fixed point

How can you distinguish between pure translation and combined motion visually?

• By color change
• By sound produced
• By weight
• By observing changes in orientation

What remains constant in pure translational motion of a rigid body?

• External forces
• Temperature
• Relative positions of all particles
• Velocity of individual particles
