Now you're getting into power. Power is essentially the ability to do work. Work is applying a force to an object to make it move a certain distance.
When talking about engines in our system of measurement, power is defined in hp.
hp = ((lb/ft) * rpm)/5252
So to make power you either need to increase torque or make the engine spin faster. As F1 engines are limited in displacement and thereby torque, they instead make power by spinning up to 19,000 rpm.
