The video explains how to calculate energy conversion efficiency by dividing useful energy by total energy and multiplying by 100 to get a percentage. It highlights that speakers have a low efficiency of around 3%, with most energy lost as heat. In contrast, the human body is highly efficient, converting food into energy, with a sprinter's performance being four times greater than a motorcycle's.

How is the efficiency of a process that converts energy calculated?

What percentage can the useful energy produced be multiplied by to express it as a percentage?

What percentage of energy do the speakers convert into sound?

What happens to the remaining energy that is not converted into useful forms?

How does the energy conversion efficiency of the human body compare to that of a motorcycle?
