Question

Which of the following statements is/are correct about uniform circular motion?

• A. Force acting on the body is zero.
• B. Acceleration of the body is non-zero.
• C. Tangential acceleration is non-zero.
• D. Radial acceleration is zero.

Answer 1

Answer: (B), (C)

The correct options are
B

Acceleration of the body is non-zero.

C

Tangential acceleration is non-zero.

In a uniform circular motion, the speed of the body must remain constant.
The velocity changes as direction keep changing.

Hence, there is a non-zero velocity which keeps changing.
Because of the constant change in velocity the acceleration of the body is non-zero.
