In a closed system, the total amount of energy remains constant according to the law of conservation of energy. Understanding what does the total energy include is fundamental to physics, as it comprises the sum of all forms of energy present within that system.

This means a system's total energy is a sum of its many constituent parts, but what is total energy made up of specifically?
