If you press an apple crate against a wall so hard that the crate cannot slide down the wall, what is the direction of (a) the static frictional force on the crate from the wall and (b) the normal force on the crate from the wall? If you increase your push, what happens to (c) fs, (d) FN, and (e) fs,max?

Newton's Second Law

Newton’s laws of motion describe the relationship between the motion of an object and forces acting on it. Newton’s law of motion has two types as follows:
