ROTATIONAL MOTION Quiz

• It reduces air resistance
• It powers the rotation
• It measures time
• It serves as the pivot about which torque and angular momentum are calculated

• They increase mass
• They apply torque with feet
• They stop external forces
• They reduce moment of inertia to increase spin rate

• It has no effect
• It destroys angular momentum
• It only affects mass
• It causes an abrupt change in angular momentum equal to the torque impulse

• It has no effect
• It only affects direction
• It inverts the vector
• It determines the sine factor in l = r p sinθ

• They are the same
• Static stability involves rotation
• Dynamic stability is weaker
• Dynamic stability arises from angular momentum, resisting changes in orientation
