2. Other Forms of Energy; Energy Transformations and the Law of Conservation of Energy The law of conservation of energy states that the total energy is neither increased nor decreased, but remains constant in a closed system…it is conserved. Energy can be transformed from one type to another or one body to another, but the amount remains constant.

3. Energy Conservation with Dissipative Forces Because frictional and opposing dissipative forces reduce the total mechanical energy, heat, light, and sound must be considered to make energy conservation really work. (chapters 14 and 15) To estimate this loss due to friction, the F fr should be added to the right, or final side, of our long conservation of mechanical energy equation. See Example 6-15
