Question

Friction always opposes the direction of motion of an object.

• A. True
• B. False

Answer 1

The correct option is B False

The frictional force opposes the motion of an object relative to its surface in contact. However, the direction of frictional force may be the same as the direction of motion of the object. For example, during walking we apply a force in the backward direction with our foot. Since friction opposes relative motion, it acts in the forwards direction and moves us forward.
