A lever works by reducing the amount of force needed to move an object or lift a load. ... You will see that levers neither increase nor decrease the amount of total effort necessary. Instead, they make the work easier by spreading out the effort over a longer distance.

What do you use a lever for?

A lever usually is used to move or lift objects. Sometimes it is used to push against objects, but not actually move them. Levers can be used to exert a large force over a small distance at one end by exerting only a small force over a greater distance at the other.

Why do levers make our work easier?

Levers make work easier by allowing people to use less force to move a heavier object.
