Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion MCQ Question
Type: MCQ-conceptual-Easy-Class 11
Which of the following statements correctly describe uniform circular motion?
A
The speed of the object remains constant while the direction of its velocity changes.
B
Centripetal acceleration is directed away from the center of the circle.
C
The magnitude of centripetal acceleration varies with time during uniform circular motion.
D
The angular speed is constant and relates to linear speed through the radius of the circle.
Correct Answer
Option A
Detailed Explanation
In uniform circular motion, the speed is constant, but the direction of velocity changes, resulting in centripetal acceleration directed towards the center. The angular speed is constant, and the magnitude of centripetal acceleration is also constant, as stated in the NCERT context.
