ROTATIONAL MOTION

What is the role of the right-hand rule in angular momentum?

• To find magnitude
• To measure speed
• To determine its direction
• To calculate energy

Can a body have angular momentum without rotating?

• No
• Only in space
• Yes
• Only if spinning

What is the law of conservation of angular momentum?

• Energy is conserved
• Linear momentum is conserved
• If net external torque is zero, angular momentum is constant
• Force is conserved

What is the effect of increasing the distance from axis on angular momentum?

• Decreases it
• Increases it
• No effect
• Depends on mass

How does doubling the speed affect angular momentum?

• Halves it
• Doubles it
• No change
• Quadruples it
