ROTATIONAL MOTION

How is the magnitude of angular momentum affected by doubling mass?

• It halves
• It doubles
• It quadruples
• No change

What is the direction of torque when r and F are in the xy-plane?

• Along x-axis
• Along y-axis
• Along z-axis
• In xy-plane

If force is doubled and r is halved, what happens to torque?

• Doubles
• Halves
• Remains same
• Quadruples

How does angular momentum change if the reference point is changed?

• It remains same
• It increases
• It may change
• It becomes zero

If a particle moves in a circular path about the origin, when is angular momentum maximum?

• When at top
• When at bottom
• Always constant
• When at sides
