Why is perpetual motion impossible? For example, can’t you just redirect some of the energy produced from a generator into keeping itself running?
In: Physics
I want to emphasize that generators do not create energy out of nowhere. Generators take existing energy (in the form of motion) and transform it into a different kind of energy (electricity). The total amount of energy does not increase. When the energy becomes electricity, it stops being motion, which means the generator *must* slow down.
