The law of conservation of energy states that the total amount of energy in an isolated system remains constant. A consequence of this law is that energy cannot be created nor destroyed. The only thing that can happen with energy in an isolated system is that it can change form, i.e. kinetic energy can become thermal energy.
Albert Einstein's theory of relativity shows that energy can be converted to mass (rest mass) and mass converted to energy. Therefore, neither mass nor pure energy are conserved separately, as it was understood in pre-relativistic physics. Today, conservation of "energy" refers to the conservation of the total mass-energy, which includes energy of the rest mass. Therefore, in an isolated system, mass and "pure energy" can be converted to one another, but the total amount of energy (which includes the energy of the mass of the system) remains constant.
Another consequence of this law is that perpetual motion machines can only work perpetually if they deliver no energy to their surroundings. If such machines produce more energy than is put into them, they must lose mass and thus eventually disappear over perpetual time, and are therefore impossible.
What else can I help you with?
Conclusion of energy conservation?
the conclusion is sumthing which concludes so conclusion of energy conservation is to conserve energy fr futher generations.....:P;):)
What law states that energy cannot be created or destroyed?
Law of energy conservation. It shows that energy cannot be created or destroyed
What is low of conservation?
The law of conservation states that energy can never be created or destroyed, only changed into a different form.
What is always true according to the law of conservation?
There is no one "law of conservation", there are several laws, such as conservation of energy, conservation of mass, conservation of electric charge, conservation of rotational momentum, etc.What is always true is that there is SOME quantity that doesn't change in the case of a closed system.
What is energy conservation and why should citizens conserve energy?
Energy conservation is that energy cannot be created or destroyed it can be transferred or transformed. We conserve energy no matter what we do. What we are really being told is to conserve usable energy which is energy not in the form of heat. We are told this to avoid the heat death of the universe this is when all the usable energy is lost due to heat.
What meant by the principal of energy conservation?
Save the environment!M!

What states have energy laws that state that energy can not be created or destroyed?
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.
How are the laws of conservation of mass and conservation of energy similar and how are they different?
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.).
What state of law of conservation of energy?
In a closed system, energy can neither be created nor destroyed.
What does the law of conservation of mass - energy state?
It states that energy can change but mass can not change Chuma.C
What does law conservation of energy state?
In a closed system, energy can neither be created nor destroyed.
What does the law of conservation of motion state?
Energy can be neither created or destroyed but can be transformed to a different type of energy.

How is friction different from the laws of conservation of energy?
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.
What did Julius von Mayer discover?
In 1841, he was the first to state the law of conservation of energy.
What is a state of energy that cannot be created or destroyed called?
That state of energy is called the conservation of energy principle. It states that energy can neither be created nor destroyed, only transformed from one form to another.
