Question

Which of the following quantities remain(s) constant during the uniform circular motion of an object?

• A. Velocity and acceleration
• B. Speed and velocity
• C. Speed and acceleration
• D. Acceleration only
• E. Speed only

Answer 1

The correct option is E Speed only

During uniform circular motion, the magnitudes of acceleration as well as the velocity remain constant but they change their direction at every instant.

Hence only speed of the object is constant in uniform circular motion.
