Question

Uniform linear motion is motion with a constant velocity (zero acceleration). Uniform circular motion is motion with___.

• A. varying speed and constant centripetal acceleration
• B. constant speed and constant centripetal acceleration
• C. constant speed and varying centripetal acceleration
• D. speed and centripetal acceleration is zero

Answer 1

The correct option is B

constant speed and constant centripetal acceleration

Uniform linear motion is motion with a constant velocity i.e. zero acceleration. Uniform circular motion is motion with constant speed and constant centripetal acceleration.
