Read the text and choose the correct answer to the question after the text:
ENERGY
Ability to do work is called energy, and when the energy is (due to) motion it is called kinetic energy.
The weight which has been lifted from the floor to the top of a table has had work on it; if we allow the weight to fall back again to the floor it will get velocity, and therefore kinetic energy. The energy was simply "stored up" in the weight when it was at rest on the table: it had energy due to its position on the table; and we call this energy potential. Or, potential energy is energy of a mass due to its position. Water, at the top of a waterwheel, has potential energy.
At it falls gradually loses this potential energy, but gets kinetic energy at the same time.
Forms of Energy. - Any matter possesses energy. Hot steam is able to do work, and we may say that heat is a form of energy. Electric current, when passed through a motor, can do work. So electric current is a form of energy.
What is energy?
