ROTATIONAL MOTION Quiz

• It cannot
• Because gravity pulls it
• Because any linear motion with a moment arm relative to a point contributes to angular momentum
• Because time is curved

• It has no effect
• Torque becomes zero
• Torque value depends on the origin
• It doubles the force

• They are the same
• Force is scalar
• Force changes linear momentum, torque changes angular momentum
• Torque affects mass

• It helps them jump
• It reduces weight
• Skaters change their moment of inertia to control spin speed
• It keeps them warm

• It stops moving
• It vanishes
• It may rotate with increasing angular speed
• It becomes liquid
