Key concepts
3 concepts
- 1
The total energy of a closed system will always be conserved, even as energy changes forms. This is known as the Law of Conservation of Energy.
- 2
Mechanical energy is the sum of kinetic energy and potential energy in a system.
- 3
Energy can be transformed into different forms, such as chemical, thermal, nuclear, or sound energy, but the total amount of energy remains constant.
