Question

Frictional force always acts in which direction?

• A. Opposite to that of the object in motion.
• B. In the same direction as that of the object in motion
• C. In any direction
• D. None of the above

Answer 1

The correct option is A Opposite to that of the object in motion.

Frictional force offers the resistance to the applied force opposing its motion. Thus, it always acts in the direction opposite to that of the object in motion. If force is applied to the left, then friction acts in the right.
