Question

A body is travelling with a constant speed in on the circumference of a circle, of the quantities
1. linear velocity
2. linear acceleration
3. centripetal force
which remains constant? ​

Answer 1

NOTHING stays constant due to change in direction

Answer 2

Explanation:

• The speed of an object is a scalar quantity while velocity is a vector quantity. If a body is travelling with a constant speed in on the circumference of a circle, its direction keeps on changing at every point.
• If direction is changing it means that the acceleration, velocity as well as centripetal force will change.
• Hence, no quantity will remain constant.
