Imagine you push a book across an incredibly slippery surface. It slides right across because there is no friction. Next, you push the same book across a rougher surface that exerts friction.

If there is applied force in the direction of the motion, and the magnitude of the applied force is more than the magnitude of the friction, the friction will cause the velocity to increase more slowly than it would otherwise.

this would be about 43%
