NEET Physics Friction MCQ Question
Consider a diagram showing a block sliding down an inclined plane with friction. The angle of inclination is . Which of the following labels correctly represents the force of kinetic friction acting on the block?
Parallel to the plane and opposite to the direction of motion
Perpendicular to the plane
Parallel to the plane and in the direction of motion
Parallel to the ground
Correct Answer
Detailed Explanation
The force of kinetic friction opposes the relative motion between surfaces, acting parallel to the plane and opposite to the direction of motion as described in the NCERT context.
