A 'Jack' uses a lever and a piston to allow a person to lift a car.

A lever is a tool which can be used to make lifting easier.

Levers are used to lift cars with a jack, pull out nails with a hammer and to break locks with a crowbar.

A lever needs a long stiff rod and a pivot.

A seesaw can work as a lever. If an adult sits close to the centre and a child sits at the far end, the child can lift the adult.
