Question

The combination of rotational motion and the translational motion of a rigid body is known as

• A. Frictional motion
• B. Axis motion
• C. Angular motion
• D. Rolling motion

Answer 1

Answer: (D)

Rolling motion

Answer 2

The combination of rotational motion and translational motion of a rigid body is known as rolling motion. In rolling motion, a body rotates about an axis while its center of mass translates. A common example is a wheel rolling on a surface.

• Frictional motion refers to motion influenced by friction, not the combination of two types of motion.
• Axis motion is not a standard term describing this combined motion.
• Angular motion is another term for rotational motion and does not include translational motion.
• Rolling motion precisely describes the combined translational and rotational motion, often without slipping.
