Question

Which one is an example of an accelerated body, moving with a uniform speed

• A. A car travelling towards west at a speed of $60km{h}^{-1}$
• B. A rocket fired in space
• C. A deer chased by a lion
• D. A rotating wheel of a car at a uniform speed

Answer 1

The correct option is D

A rotating wheel of a car at a uniform speed

Explanation for correct option:

D: A rotating wheel of a car at a uniform speed

1. The velocity keeps on changing due to continuous change in the direction of motion.
2. Therefore, circular motion is an example of an object moving with acceleration but with uniform speed.

Hence, the correct answer will be (D).
