ROTATIONAL MOTION

How does the velocity of a point on a rolling object vary with its position?

• It is always constant
• It decreases with height
• It depends on both translational and rotational motion
• It is independent of rotation

What is the role of the axis in rotational motion?

• It absorbs energy
• It reduces friction
• It serves as the fixed line about which the body rotates
• It increases speed

What is the motion of a rigid body if all its particles move along parallel paths with the same velocity?

• Rotational motion
• Rolling motion
• Pure translational motion
• Oscillatory motion

What determines the linear velocity of a point on a rotating rigid body?

• Mass of the point
• Color of the body
• Its distance from the axis of rotation
• Temperature of the body

Why is the motion of a rolling cylinder not considered pure translational motion?

• Because it moves slowly
• Because it is circular
• Because it is on an incline
• Because different particles have different velocities
