Physics · Circular Motion & Momentum

''Rotation'' refers to an object's spinning motion about its own axis. "Revolution" refers to the object's orbital motion around another object. For example, Earth rotates on its own axis, producing a 24-hour day. Earth revolves around the Sun, producing the 365-day year. 

Answer: REVOLUTIONExplanation:Revolution refers to the motion of an object around another object along a fixed path or orbit.Example: Earth revolves around the Sun.Rotation refers to an object spinning on its own axis.Example: Earth rotates on its own axis, causing day and night.

Rotation — IncorrectRotation means spinning about its own axis, not moving around another object.Example: Earth rotating on its own axis causes day and night.But Earth revolving around the Sun (orbital motion) is not rotation

Both — IncorrectIf the question specifically asks about orbital motion around another object, only revolution is correct.Both would be correct only if the question asked about motion around another object AND spinning on own axis — but here it's only about orbital motion.

None — IncorrectSince "revolution" correctly describes orbital motion around another object, "None" is wrong.
