Front

What is the relationship between work, force, and distance?

Back

Work = Force × Distance

Front

What is the definition of mechanical advantage?

Back

The ratio of output force to input force in a machine.

Front

What does it mean if a machine has a mechanical advantage greater than 1?

Back

It means the machine can lift more weight than the input force applied.
