Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 11
Assertion (A): In uniform circular motion, even though the speed is constant, there is always acceleration.
Reason (R): The direction of velocity changes continuously in uniform circular motion.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false.
Correct Answer
Option A
Detailed Explanation
In uniform circular motion, the speed remains constant but the direction of velocity changes, which results in centripetal acceleration towards the center. Thus, even with constant speed, acceleration is present due to direction change.
