Does energy have the ability work?

Energy and Work Energy is the capacity to do work or to produce heat. Internal energy is the sum of kinetic energy and the potential energy. The KE would increase because heating something causes an increase in temperature. Since the kinetic energy has increased the internal energy has also increased.

What is the 3 types of energy?

Potential energy is stored energy and the energy of position.

  • Chemical energy is energy stored in the bonds of atoms and molecules.
  • Mechanical energy is energy stored in objects by tension.
  • Nuclear energy is energy stored in the nucleus of an atom—the energy that holds the nucleus together.

What does energy actually mean?
