Question

In a uniform circular motion, ___

• A. the motion of an object takes place in a circle at a constant speed
• B. the motion of an object takes place in a circle at a constant velocity
• C. the motion of an object takes place in a circle at a constant tangential acceleration
• D. the motion of an object takes place in a circle with varying speed

Answer 1

The correct option is A

the motion of an object takes place in a circle at a constant speed

In a uniform circular motion, the motion of an object takes place in a circle at a constant speed. Here, the velocity varies due to change in direction of an object at each instant. This gives varying tangential acceleration.
