Question

What is the example of movement of a body around a circular path?
1. Equal velocity, variable acceleration
2. same speed, same velocity
3. same speed, variable velocity
4. same speed, variable acceleration

Answer 1

Correct Answer - Option 1 : Equal velocity, variable acceleration

The correct answer is Equal velocity, variable acceleration.

• When a body rotates with a fixed velocity on a circular path, it is called uniform circular motion.
• In a uniform circular motion, the direction of acceleration (concentric acceleration) is always towards the center.
• Its magnitude remains fixed, but its direction varies. During uniform circular motion the speed and the angular rate of rotation will remain constant while during non-uniform motion the rate of rotation keeps changing.
• Let's understand with some of the examples of circular motion include a rotating ceiling fan, the blades in a windmill, gears in gas turbines, and a man-made satellite that revolves around the earth.
