Does the law of Conservation of energy relate to everything?

Answer 1

it changes forms and energy can not be created or destroyed

Answer 2

Because everything has energy. If something exists, it has energy. Energy is always conserved and never destroyed. If any physical or chemical reaction takes place, there is a transfer (note not destruction of) energy. Picture a match for example. The tip of the match has potential chemical energy. When this energy is released, it is released rather quickly as a highly exothermic reaction. Energy is converted into heat and light (as shown by the flame of the match). The wood of the match has chemical potential energy as well. As the match can burn, it has chemical potential energy. Energy is also separated from the reaction through the smoke and release of gases). Now think of a car as an example of a physical reaction. I can tell you this all from experience since I recently totaled mine =( When you accelerate, the chemical potential energy of gasoline is released, creating a violent explosion which the engine controls in order to move the pistons and down the line the wheels as well. This chemical energy is converted into kinetic energy (the energy of anything on motion). This kinetic energy can be converted to heat energy by applying the brakes. Applying the brakes essentially removes some of the kinetic energy of the automobile, and converts it to heat which can be found in the disc brakes. If you ever drove a car and applied the brakes, placing your hand near (warning: not on) the disc brakes will show you that heat is emanating from the rotors. Even stopping from a slow speed will accomplish this. Energy is never created or destroyed, rather simply converted and removed from one area and moved to another. If an object exists it has energy.

Answer 3

If potential energy increases, some other form of energy must decrease. If potential energy decreases, some other form of energy must increase. The same happens if you consider any other type of energy - if it increases, some other form of energy must decrease. The total amount of energy (in a closed system) remains constant.

Answer 4

Yes, the law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or converted from one form to another. This concept applies to all systems and processes in the universe.

Answer 5

Yes. At least, no exceptions have been found so far.

Answer 6

it changes forms and energy can not be created or destroyed
