A wheel rotates about an axis passing through the center and prependicular to the plane with slowly increasing angular speed. Then it has
Correct answer: D. Tangential velocity but acceleration having both components
- A. Radial velocity and radial acceleration
- B. Tangential velocity and radial acceleration
- C. Tangential velocity and tangential acceleration
- D. Tangential velocity but acceleration having both components
Explanation
Option D is most appropriate as when the body moves in a circular path it always possesses tangential velocity and radial acceleration but when it moves with increasing angular speed it possesses another component of acceleration that is the tangential acceleration

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.
