Front

What is the equation for force?

Back

F = mass × acceleration

Front

What is mechanical advantage?

Back

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

Front

How do you calculate mechanical advantage?

Back

Mechanical Advantage = Load Force / Effort Force

Front

What does a mechanical advantage greater than 1 indicate?

Back

It indicates that the machine multiplies the input force.
