What is the big idea of energy transfer in elementary science?

Energy can be transferred between objects, and can change its form.However, energy is neither created nor destroyed.(Law of Conservation of Energy)


What is energy that can not be created or destroyed?

Yes...cannot be lost. However, quantum theory says that at sufficiently high speeds mass becomes energy. [Example: A fission or fusion reaction, in both cases a tiny bit of matter is lost and enormous energy gained when an atom is broken open.] It follows that energy would become mass if one could slow it down enough. Aside from a nuclear reaction, the only thing that changes with energy is the state....kinetic energy, static energy, etc. The famous "E=MC^2" works as follows: E = Energy M = Mass C = The speed of light Energy equals mass times the speed of light squared....a lot of potential energy in mass.


First law of thermodynamics states what?

The first law of thermodynamics states that the energy of the universe is constant. In other words, energy is never created or destroyed (conservation of energy). However, this simply states the total energy of a system is constant. This quanta of energy can still be changed into various forms (potential, kinetic, thermal, etc.) through physical and/or chemical processes. To clarify this, we will look at a very fundamental example: an apple falling on Newton's head. When the apple falls from the tree, its initial potential energy is converted to kinetic energy (it's in movement since it's falling), which is then transferred to the surrounding air atoms and Newton's head. Now, when applying this same notion to a thermodynamic process, we can write it as a mathematical equation: Change in internal energy=q-w where q=heat added to the system by its surroundings and w=work done by the system on its surroundings. The idea is relatively How exactly did we get this equation? The idea is really quite simple. The first law renders that energy cannot simply be "lost along the way"--it has to do something. Thus, when energy (in the form of heat) is added to a thermodynamic process, two things can happen: a change in internal energy or work.


How does conduction and convection and radiation relate to the law of conservation of energy?

Heat energy is transferred from one place to another; no energy is created or destroyed. It is possible for heat energy to be produced or absorbed (this has nothing to do with conduction, convection, or radiation); however, total energy is still conserved. For example, the heat energy produced will reduce the amount of some other type of energy.


What law states that energy can change form but is never created or destroyed?

It is the Law of Conservation of Energy, aka the First Law of Thermodynamics.The concept of energy is one of the most fundamental concepts of science.This is the first law of thermodynamics and it is worth saying in several ways.(A) Energy is conserved.(That is short and accurate answer but non-scientists are not used to the word "conserved" being used in this way. But, scientists use it to mean "Stays the same" all the time.)(B) Energy can change from one form of energy to another, but energy can not be created or destroyed.(This is a fundamental law of Nature and the first law of thermodynamics, that energy of a closed system can never change. Sometimes it is said that "the total energy of the universe is always the same." )Discussion:Nature provides us with the Law of Conservation of Energy, whichever way you want to say it. It was about 400 years ago that science started to understand energy. At first it was only kinetic energy, the energy of motion, that was observed unchanged.Soon this was expanded to include gravitational potential energy. Later this expanded to other forms such as elastic potential energy, heat energy, chemical energy, nuclear energy, electrical and many other forms, including the famous "mass energy," E=mc2.How grand to know that the first law of thermodynamics says that we will never run out of energy. Alas, the second law says that Entropy is the problem and energy cannot always be used to do work.Aside: There is a big discussion in cosmology now about "dark energy." This should not be confused with the possibility that maybe energy is not conserved. The truth is that cosmologists have no idea what this "dark energy" is and it is not even a sure thing that it is energy.)

What is the scientfic theory?

No idea because there are so many but I'm gonna go with the first law of physics: Energy cannot be created or destroyed.


What is energy concervation?

That means that in an isolated system, the total amount of energy remains constant. Energy can not be created or destroyed.In physics, conservation of energy is dictated by a law that states that energy levels of a system are conserved over time, thus preventing fluctuations.

What is the law that states that mass is neither created nor destroyed during chemical reactions or physical changes?

The law of conservation of matter states that matter cannot be created or destroyed in an ordinary chemical reaction.


Can you put less work in than is put out?

Never, that would lead to things like perpetual motion machines which, whilst a nice idea, are impossible due to the conservation of energy rule - energy cannot be created or destroyed, it can only be transferred. The factors which reduce output include internal friction, and heat or light energy being emitted.

What is the most important idea of the law conversation of energy?

The most important idea of the law of conservation of energy is that however and how much it is spent, energy is not lost nor destroyed, but only changes form.


Did Einstein say energy can neither be created or destroyed?

Not really. The idea of "Conservation of Energy" developed gradually over time, with more and more of types of energy (that is, what we now understand to be different types of energy) being recognized as such, and with the understanding that, for example, a specific amount of mechanical energy is always converted to a specific amount of heat energy.
