ROTATIONAL MOTION

Which axis represents the axis of rotation in rotational motion as described in the text?

• x-axis
• y-axis
• z-axis
• origin

What determines the difficulty in changing the rotational motion of a body?

• Angular speed
• Linear speed
• Moment of inertia
• Radius

Which factor does NOT affect the moment of inertia of a body?

• Mass distribution
• Axis of rotation
• Color of the body
• Shape

Which physical quantity is conserved in rotational motion when no external torque acts?

• Linear momentum
• Energy
• Torque
• Angular momentum

How does the moment of inertia of a body change when the axis of rotation is changed?

• It remains constant
• It always increases
• It changes depending on the axis
• It becomes zero
