Answer:
Explanation:
The mechanical energy of a body or a whole physical system is basically the sum of kinetic energy and potenital energy. Basically, you can defined it as the energy responsible for movements, because potential energy depends on the position and kinetic energy on the velocity, and both follow the conservation of energy law, which means the exchange one another to develop movement.
Therefore, the right answer is B) mechanical. A motor uses the attracting and repelling forces of magnets to create rotational motion, which result in mechanical energy.
