Example(s) of spin motion is/are:
Correct answer: E. Both the daily rotation of the earth and flywheel about its own axis
- A. The daily rotation of the earth about its own axis
- B. Jumping of a paratrooper from an helicopter
- C. Flow of a viscous liquid
- D. Rotation of flywheel about its axle
- E. Both the daily rotation of the earth and flywheel about its own axis
Explanation
Spin motion is the movement of an object about its own axis, which is depicted by;(i) the daily motion of the earth(ii)flywheel rotation about its own axis.

About Angular and Linear Quantities
Rotational motion relates angular displacement, angular velocity and angular acceleration to linear displacement, tangential velocity and tangential acceleration through the radius. Questions use radians, v equals r omega and tangential acceleration, while distinguishing tangential velocity from centripetal acceleration and angular quantities from their linear counterparts.
