प्रश्न
How does uniform circular motion differ from uniform linear motion?

उत्तर
When a force acts on a body at rest which is free to move, the body starts moving at a constant speed in a straight path in the direction of the force. This type of motion is called uniform linear or uniform translational motion.
Whereas when a body or a particle moves with a constant speed in a circular path, its motion is said to be uniform circular motion.
