Question

The important characteristic that distinguishes uniform from non uniform circular motion are

• A. Uniform circular motion has radial acceleration and radial velocity, while non uniform motion lacks it
• B. Uniform circular motion has radial acceleration and tangential velocity, while non uniform motion lacks it
• C. Non uniform circular motion has tangential acceleration , while uniform circular motion lacks it
• D. Non uniform circular motion has tangential acceleration and radial velocity, while uniform circular motion lacks it

Answer 1

The correct option is C Non uniform circular motion has tangential acceleration , while uniform circular motion lacks it

In a uniform circular motion, the tangential speed always remains constant, while in a non uniform circular motion, this velocity changes and hence tangential acceleration exist.
Thus option c is the correct option
