The law of conservation of energy is that energy cannot be created or destroyed, but it can be transferred or transformed from one form to another (including transformation into or from mass, as matter). The total amount of energy in a closed system never changes.
Energy in a system may be transformed so that it resides in a different state. Energy in many states may be used to do many varieties of physical work. Energy may be used in natural processes or machines, or else to provide some service to society. The generic name for a device which converts energy from one form to another is a transducer. Energy transformations in the universe over time are generally characterized by the various kinds of energy available since the Big Bang, including gravitational energy and electromagnetic waves.
Example: Suppose you push a book across a table. The book has kinetic energy but its motion decreases as it slides. It seems like the book's energy is being lost. Actually, the kinetic energy is not lost, it just changes form. The kinetic energy is converted by friction into thermal energy, another form of energy. The thermal energy makes the book, the table, and the air a little warmer.

Energy cannot be created or destroyed - it can only be converted from one form to another.

∙ 8y agoA 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.

What law of the scientific rule states that energy cannot be created or destroyed?
The law of Conversation of Energy
What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
How are the law of conservation of enegry and the law of mass similar?
The Law of conservation of Energy applies to mass as mass is a form of energy, E=mc2.
How The Law of Conservation of Energy Applies To Energy?
in closed systems
What does the law of conservation state?
The law of conservation states that energy can neither be created or destroyed but can be found existing in different forms
What law of the scientific rule states that energy cannot be created or destroyed?
The law of Conversation of Energy
What law says in chemical change energy is neither created or destroyed?
Scientists call this law the law of conservation of matter
Law that states that energy cannot be created or destroyed?
The law of Conservation of Energy. Actually, that law has been superceded now by a slightly different one. Recently (maybe 100 years ago) it was learned that energy can become mass and mass can become energy. So the law had to be modified to say that the total combination of mass and energy can't be created or destroyed.
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.
What states have energy laws that state that energy can not be created or destroyed?
Law of conservation of energy. Energy can't be created or destroyed is the basic statement of the law of conservation of energy.
Why the law of conservation of energy can mean that you do not have unlimited sources of energy?
That is because the law of conservation of energy states that you can not create new energy.
How is friction different from the laws of conservation of energy?
There are no "laws" of conservation of energy, just the law of conservation of energy. The existence of friction doesn't change anything - the law of conservation of energy still holds.
What law states that energy is never created or destroyed?
That is called Conservation of Energy. It is also known as the First Law of Thermodynamics.
What is th law of energy called?
the law of conservation of energy
Is the law of conservation of charge the law of conservation of energy?
No, those are two separate conservation laws. Charge is not energy. They are entirely different things.
How does Einsteins equation Emc2 support the law of conservation of energy?
If you consider mass and energy to be equivalent and interchangeable, it does not conflict with the law of conservation of energy. E=mc2 states that energy is mass and mass is energy, so it does not disprove the law of conservation of energy.
What chemical equations violates the law of conservation of energy?
Any chemical equations violates the law of conservation of energy.
