ROTATIONAL MOTION

What type of motion can a rigid body fixed along a line undergo?

• Pure translational motion
• Vibrational motion
• Rotational motion only
• Combination of translational and rotational motion

What happens to angular momentum when a torque is applied in the direction of rotation?

• It decreases
• It remains same
• It becomes zero
• It increases

What is the significance of Eq. (6.44) in physics?

• It defines torque
• It calculates energy
• It expresses conservation of angular momentum for fixed-axis systems
• It measures inertia

How is angular momentum conserved in asymmetric rotating bodies?

• Total L is not conserved
• L⊥ changes
• Only the axial component Lz is conserved
• None is conserved

What is the outcome of applying a constant torque to a rotating system?

• Speed decreases
• Rotation stops
• Angular acceleration occurs
• Energy is conserved
