Physics-Uniform Circular Motion
NEET Physics Uniform Circular Motion Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 11
Assertion (A): In uniform circular motion, the speed of the object remains constant, but its velocity changes. | Reason (R): The direction of velocity vector 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, but R is true.
Correct Answer
Option A
Detailed Explanation
In uniform circular motion, the speed is constant, but the velocity, which is a vector, changes direction continuously as it is always tangential to the circular path. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.
