What is the direction of the force of friction in relation to the motion of an object?
Show answer & explanation
Correct answer: D
Explanation
Correct Answer:
Option 4: Always opposite to the direction of motion
Explanation:
Friction is a contact force that always acts opposite to the direction of motion. It resists movement and reduces speed. It depends on the nature of surfaces and applied force. It is essential for walking, braking, and stability.
Additional Facts:
Option 1: Same direction is incorrect.
Option 2: Perpendicular is incorrect.
Option 3: Random is incorrect.
