The law of conservation of energy<\/strong> is one of the basic laws of physics, along with the conservation of mass <\/strong><\/a>and the conservation of momentum. The law of conservation of energy<\/strong> states that energy can change<\/strong> from one form<\/strong> into another, but it cannot be created or destroyed<\/strong>.<\/div><\/div>\n

Or the general definition is:<\/p>\n

The total energy of an isolated system remains constant over time.<\/span><\/p>\n

Energy<\/strong> can be defined as the capacity for doing work<\/strong>. It may exist in various forms and be transformed<\/strong> from one type of energy to another in hundreds of ways.<\/p>\n

For example, burning gasoline to power cars is an energy conversion process we rely on. The chemical energy<\/strong> in gasoline is converted<\/strong> to thermal energy<\/strong>, then converted to mechanical energy<\/strong> that makes the car move. The mechanical energy<\/strong> has been converted to kinetic energy<\/strong>. When we use the brakes to stop a car, that kinetic energy<\/strong> is converted by friction back to heat or thermal energy<\/strong>.<\/p>\n

A consequence of the law of conservation of energy is that a perpetual motion machine of the first kind, which produces work without the input of energy, cannot exist.<\/p>\n

The concept of energy conservation<\/strong> is widely used in many fields. In this article, the following fields are discussed:<\/p>\n
