Question

explain with suitable example and figure whether or not the force of friction always acts opposite to the direction of motion

Answer 1

Force of friction does not always act opposite to the direction of motion. For instance, while walking in the forward direction, both direction of motion and force of friction acts in the forward direction. This, in this case, friction is actually helping in walking.

Actually, the force of friction acts in the direction opposite to the relative motion ( motion of one body with respect to other) between bodies. 

Hope this will helps you.

Answer 2

Answer:

--------------------

Explanation:

The frictional force always acts in opposite direction of motion. Frictional force slows down the speed of an object. For example when a person roll the ball on the ground. ... It is due to the frictional force acting opposite to the direction of its motion.
