Understanding Uniform Circular Motion
Uniform circular motion refers to motion along a circular path at a constant speed. In this scenario, the object’s speed remains constant, but its direction changes continuously, resulting in acceleration towards the center of the circle.
Analyzing the Options
- Motion of a racing car on a circular track
- This motion is often not uniform because a racing car changes its speed while navigating turns. Drivers accelerate or decelerate, which means the speed is not constant.
- Motion of the moon around the earth
- The moon moves in a nearly circular orbit at a constant speed, making this a classic case of uniform circular motion.
- Motion of a toy train on a circular track
- If the toy train moves at a constant speed around the track, it exemplifies uniform circular motion.
- Motion of the seconds hand on the circular dial of a watch
- The seconds hand moves at a constant speed, completing a full revolution in a fixed time, thus representing uniform circular motion.
Conclusion
The correct answer is option 'A' – the motion of a racing car on a circular track. This is because the car typically experiences variations in speed, unlike the other options, which maintain a constant speed while moving in a circular path.

An object moving in uniform circular motion is moving in a circle with a uniform or constant speed. The velocity vector is constant in magnitude but changing in direction.
Hence, the motion of a racing car on a circular track changes it speed, that is, it increases or decreases speed during the drive not a case of uniform circular motion.
