NEET Physics Friction Assertion Reason Question
Assertion (A): Kinetic friction is independent of the velocity of the moving object.
Reason (R): The coefficient of kinetic friction depends only on the surfaces in contact.
Both A and R are true and R is the correct explanation of A.
Both A and R are true but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
The NCERT context states that kinetic friction is nearly independent of velocity and the coefficient depends only on surfaces, but these are separate aspects.
