NEET Physics Friction MCQ Question
Which of the following statements about friction is correct?
Kinetic friction is always greater than static friction.
The coefficient of kinetic friction depends on the surfaces in contact.
Kinetic friction is independent of the area of contact.
Kinetic friction increases with the velocity of the sliding object.
Correct Answer
Detailed Explanation
The NCERT context states that kinetic friction, like static friction, is independent of the area of contact and is nearly independent of velocity. Therefore, option C is correct while the others are misconceptions.
