The book is held in place by the force you are putting against it. Remove your hand (remove the force) and the book will fall due to gravity.
when you push your hand against a wall the wall is 'pushing' against you that is why you feel your hand being pushed.
If you push against a wall, the wall will exert an equal and opposite force back against you, according to Newton's third law of motion. Therefore, you will not be able to move the wall. The force you apply will result in either the wall moving if it is not fixed, or you using energy without moving the wall.

No one he put all his weight forward then he fell.(but was it really an accident, or murder...)
If you push as hard as you can against a wall while wearing roller-skates, you will exert a force on the wall but since the wall cannot move, an equal and opposite reaction force will push you in the opposite direction. This is due to Newton's third law of motion, stating that for every action, there is an equal and opposite reaction. As a result, you will be pushed backward away from the wall.
Beat them against a wall until their brains fall out and then you measure it.
no the only reason their eyes fall out is because since they are bracosaphalic (have a pushed in face) they need to be walked using a harness rather a color and if it is wearing a collar and it gets pulled to hard they can fall out.
it means watch the wall or you will get pushed into it
Infront of the sea wall the gradient dips down because the waves are pushed up against the wall and there is a strong backwash so that's why it dips down. This is beach scouring.
