ROTATIONAL MOTION

What is the main reason different points on a rolling object have different velocities?

• Due to gravity
• Due to air resistance
• Due to superposition of translational and rotational velocities
• Due to deformation

• Rolling motion
• Oscillatory motion
• Pure translational motion

What is the motion of a satellite orbiting Earth?

• Rotation about a fixed axis
• Pure translation
• Oscillation
• Revolution, not rotation about a fixed axis

What is the condition for a body to be in pure rotational motion?
