Physics 20 Lesson 27 Conservation of Energy
... The Law of Conservation of Energy states that the total amount of energy in a system remains constant. The energy may be transformed from one type to another, from kinetic to potential or kinetic to heat, but the total amount of energy is conserved. For example, imagine a skier starting from rest at ...
