Question

Which of the following quantity remains constant in a uniform circular motion? (1) velocity (2) speed (3) both velocity and speed (4) None of these

• A. velocity
• B. speed
• C. both velocity and speed
• D. none of these

Answer 1

The correct option is B

speed

Uniform circular motion:

1. A circular motion is a body movement that takes a circular path.
2. The motion of a body moving at a constant speed along a circular path is known as uniform circular motion.
3. The velocity varies due to changes in the direction while the speed remains constant.

Hence, Option(B) is correct.
