ROTATIONAL MOTION Quiz

• It increases the rotational speed
• It reduces friction
• It aligns with angular momentum
• It acts perpendicular to the angular momentum vector

• Linear velocity
• Angular velocity
• Torque
• Angular momentum

• Horizontal plane
• Inclined plane
• Random plane
• Vertical plane

• It reduces tension in strings
• It decreases torque
• It makes the rim lighter
• It increases angular momentum, enhancing stability

• It reduces angular momentum
• It makes the rim fall faster
• It has no effect
• It increases moment of inertia, thus increasing angular momentum for same angular speed
