Work and Simple Machines

This is done when a force causes an object to move in the same direction that the force is applied.

• force

• work

• power

• input force

• output force

How much larger the output force is compared to the input force.

• mechanical advantage

• efficiency

• simple machine

• compound machine

• inclined plane

The ratio of the output work to the input work.
