<human>:  Explain the laws of conservation of energy
<bot>: The law of conservation of energy states that energy can neither be created nor destroyed, but can be transformed from one form to another. In other words, energy cannot be created out of nothing, and it cannot be destroyed completely. This means that the total amount of energy in a closed system remains constant over time. Furthermore, energy is always transferred between the components of a system in a balanced way, and no energy is lost. Energy can change its form, such as when energy is transformed from electrical to mechanical or from heat to work.
