    • The law of conservation of energy explains why a pendulum eventually stops due to friction converting kinetic energy into heat.
    • In a closed system, the conservation of energy dictates that the initial energy equals the final energy.
    • Nuclear reactions demonstrate conservation of energy as mass is converted into a large amount of energy.
