That's the law of "Conservation of Energy". It says you always end up with the
exact same amount of energy you started out with.
That law has been updated a bit in recent years. There used to be two separate
conservation laws ... one for energy and another one for mass, and they both said
that it couldn't be created or destroyed. Scientists were very worried when they did
some very important experiments, and they saw mass being destroyed and energy
being created! Digging in further, they discovered that energy could change into mass,
and mass could change into energy. That discovery actually made things simpler, because
now, instead of two conservation laws, we only need one. It says that mass and energy
can change from one to the other, but whatever the total (mass + energy) is at the
beginning, the total (mass + energy) must be the same at the end.
But how can you add them up ? How much energy makes how much mass ??
And how much mass makes how much energy ???
We're so happy you asked that.
Maybe you've heard that [ E = M c2 ] .
That's the answer to that one.
That law is known by either of the following two names:
The law of Conservation of Mass-Energy.
conservation
The Law of Conservation of Energy states that the total amount of energy remains constant - energy will not be created or destroyed.
One of most basic laws of science is the Law of the Conservation of Energy. It states that energy cannot be created or destroyed; it can only be changed from one form to another.
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.(see the related link below)Energy cannot be created or destroyed - it can only be converted from one form to another.
Whoever wrote the Law of Conservation of Energy (This states that energy can neither be created nor destroyed.)
The law of conservation states that energy can neither be created or destroyed but can be found existing in different forms
The law of conservation of energy states that energy is neither created nor destroyed, but it can be transformed from one form to another.
Science always states "...energy can neither be created or destroyed - simply transformed from one state to another..."
The first law of thermodynamics states that energy can be transformed, but not created nor destroyed. In a nuclear reaction, mass is transformed into energy.
The Law of Conservation of Energy states that energy can not be created or destroyed, it can only be transformed. So, kinetic energy is not created, it is transformed from potential energy, and vice versa.
The law of conservation of energy states that "energy can not be created (made) or destroyed (made gone)"
energy can be transformed in different ways but can never be created or destroyed.
The law of conservation of energy states that energy cannot be created or destroyed, but only transformed into a different form.
true
Yes
no energy is destroyed in the process
Energy flows from one type toanother following the laws of thermodynamics. The 1st law states that no energy is created or destroyed, and the 2nd law states that energy will move from an area of high concentration to an area of low concentration or that the entropy of a closed system will remain constant or diminish.
The Law of the Conservation of Energy. Stating it can be neither created or destroyed but changed from one form to another.
