A conservation law, such as this one, can be stated in different ways; for example:* The total amount of energy in a closed system doesn't change over time.
* Any change in energy in a system is equal to the energy that comes in, minus the energy that goes out.
* There is a quantity called energy, that can't be created or destroyed.
The laws of conservation of mass and conservation of energy are similar in that both state that the total amount of mass or energy in a closed system remains constant over time. However, the conservation of mass applies specifically to mass, while the conservation of energy applies to energy in its various forms (kinetic, potential, etc.).
Friction is a force that resists relative motion between two surfaces, leading to energy loss in the form of heat. The laws of conservation of energy state that energy cannot be created or destroyed, only transferred or transformed from one form to another. Friction causes energy to be dissipated, leading to a loss of mechanical energy in a system.
Both conservation laws are applied. The conservation of momentum and conservation of energy. However, in an inelastic collision, kinetic energy is not conserved. But total energy IS CONSERVED and the principle of conservation of energy does hold.
The most relevant conservation law in this case is probably the Law of Conservation of Energy. The computer uses electrical energy, most of which is eventually converted into heat. A small part will go out as sound, and as low-frequency electromagnetic waves.
The concept that energy cannot be created or destroyed is a fundamental principle known as the Law of Conservation of Energy. It is a universal law of physics that applies in all states and is not specific to any particular state's energy laws.
There are many different laws of conservation, but they are essentially the same. For this example I will use energy. The laws of conservation of energy say that energy in = energy out. This is to say that energy cannot be destroyed or created.
There are many laws of conservation. Some of the better-known ones are the law of conservation of energy, of momentum, and of rotational momentum.There are many laws of conservation.

No, those are two separate conservation laws. Charge is not energy. They are entirely different things.

Steve Irwin spent his career studying wildlife and fighting for wildlife conservation. A partial solution to the energy crisis lies in better energy conservation. The conservation of energy is a major part of Newton's Laws.
The most relevant conservation law in this case is probably the Law of Conservation of Energy. The computer uses electrical energy, most of which is eventually converted into heat. A small part will go out as sound, and as low-frequency electromagnetic waves.

Sure, total energy is always conserved.
The concept that energy cannot be created or destroyed is a fundamental principle known as the Law of Conservation of Energy. It is a universal law of physics that applies in all states and is not specific to any particular state's energy laws.
There are several conservation laws in physics, and many of them tell an astronomer what is, and what isn't, possible. This can help explain how certain things happen, or even predict what will happen. Among the laws of conservation that are relevant in astronomy are: conservation of mass; conservation of energy; conservation of momentum; conservation of rotational momentum; conservation of charge.
