What is energy and how is it classified?

Here is the definition, examples of energy, and a look at the way it is classified. In science, energy is the ability to do work or heat objects. It is a scalar physical quantity, which means it has magnitude, but no direction. Energy is conserved, which means it can change from one form to another, but isn’t created or destroyed.
