In the diagram on the left, where would the LEAST amount of force be needed to move the weighted box?

Simple machines reduce the amount of force needed to do work such as lifting an object. The simple machine shown below is a lever. A downward force on one end of a lever moves the other end up. A playground seesaw or a crowbar are common examples of levers.

The amount of force needed to raise the box sitting on the lever depends on where the force is applied. The more distance between the weight and the force, the smaller the force that is needed.

A . at point A
B . at point B
C . at point C
D . at point D
E . next to the box
