When Friction acts in the Forward Direction

Friction is of two types Static Friction and Kinetic Friction. Kinetic Friction is always opposite to the direction of the motion but static friction can be in the same or in the opposite direction. Here is an explanation of different cases when friction comes in the same direction.
