ROTATIONAL MOTION

What is the motion of a solid cylinder moving down an inclined plane while rotating?

• Sliding motion
• Spinning motion
• Rolling motion
• Bouncing motion

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

• It is always constant
• It depends only on height
• It is the vector sum of translational and rotational velocities
• It is independent of rotation

What is the role of the fixed axis in rotational motion?

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

What is the motion of a rigid body that slides down an incline without rotating?

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

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

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