Levers: lifting heavy things with a little push, sentence 2

The secret is distance from the pivot: push far from it and you need only a little force, while close to it the bar pushes very hard but moves only a little.

Who acts: secret, you, bar · What happens: be, need, push, move · To what, where: distance, pivot, little force, little
