3.2 Review

If you push a book against the wall hard enough, it will not slide down even though gravity is pulling it. Use waht you know about friction and Newton's laws of motion to explain why the book does not fall.

With my amount of force pushing to the opposite direction of the book and the wall mass I could make  that the book cuold remain in the same place because the two forces were balanced so as Newton says if two forces acting in opposite directions on an object are balanced, the object don't move.
