NEET Physics Friction MCQ Question
Consider a diagram showing a block sliding down an inclined plane with friction. The angle of the incline is , and the block is acted upon by gravitational force, normal force, and frictional force. Which of the following correctly labels the direction of the frictional force in this scenario?
Opposite to the direction of the block's motion.
Parallel to the direction of the block's motion.
Perpendicular to the plane of the incline.
Same direction as the gravitational force.
Correct Answer
Detailed Explanation
The frictional force opposes the relative motion between surfaces in contact, which in this case is opposite to the direction of the block's motion as it slides down the incline.
