PHY 101 Circular Motion Objective Question
Take CBT

Question

An object moving in a circular path at constant speed is still accelerating because:
Options
A its angular velocity is zero.
B its speed is constant, so it is not accelerating.
C the direction of its velocity is changing.
Correct Answer
D there is no net force acting on it.
Correct Answer

Option C is the correct answer.

Detailed Explanation

The lecture clarifies that even with constant angular speed, a body in circular motion is accelerating because the direction of its velocity is constantly changing.

Hint

Acceleration is defined as a change in velocity. Velocity is a vector quantity, having both magnitude and direction.
