What is the central idea of the law of conservation of energy?
The central idea of the law of conservation of energy is that energy cannot be created or destroyed in an isolated system; it can only change forms or be transferred between objects. This principle is fundamental in understanding the behavior of energy in various physical processes and systems.
Why can't matter be destroyed?
The law of conservation of mass states that matter cannot be created or destroyed, only transformed into different forms. This principle is based on the idea that atoms are never lost or created in chemical reactions, but are rearranged into new combinations. Therefore, matter can change from one form to another, but it cannot be completely destroyed.
Which idea is centeral to the law of conservation of energy?
The idea is that you can define a quantity, called "energy", that remains constant over time. That is, if no energy escapes from a system, and no energy comes into a system, the total amount of energy will remain constant. Note that there are different types of energy, and you can convert between the different types - but the TOTAL amount remains constant.
What evidence is there that energy is conserved in physical systems?
One key piece of evidence that energy is conserved in physical systems is the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed. This principle has been consistently observed and tested in various experiments and real-world applications, providing strong support for the idea that energy is conserved in all physical processes.
What implications arise from the fact that there is a finite amount of energy in the universe?
The implications of the finite amount of energy in the universe include the idea that energy cannot be created or destroyed, only transformed. This means that as energy is used and transformed, it becomes less available for future use. It also suggests that there are limits to the amount of energy that can be harnessed and utilized, which may impact future technological advancements and sustainability efforts.
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.

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.
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.
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.
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.
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.
