The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. This means that the total energy of a system remains constant. So, at the top and bottom of a system, the total energy would be the same, with potential energy at the top transforming into kinetic energy at the bottom.
The law that states energy cannot be created or destroyed is the First Law of Thermodynamics. It is also known as the Law of Conservation of Energy, which states that energy can only change forms or be transferred from one system to another.
The law of conservation of energy states that energy cannot be created or destroyed, but can only be converted from one form to another. This means that the total amount of energy in a closed system remains constant over time.
The first law of thermodynamics states that energy cannot be created or destroyed, only converted from one form to another. It is also known as the law of conservation of energy.
The first law is also known as law of conservation of energy. It say that the energy can neither be created nor be destroyed but can only be transferred. Its is given by this equation dQ = dU + dW .
Say this "even when friction occurs and physical changes take place, the law of conservation of mass states that no matter is lost in the process". (though it may seem like matter has been lost, some of the matter goes in the atmosphere or onto the ground depending on what you are applying friction too)
There are many different laws of conservation, but they are essentially the same. For this example I will use energy. The laws of conservation of energy say that energy in = energy out. This is to say that energy cannot be destroyed or created.

Let's say that everything is an example of the Law of Conservation of Energy - because this is a law that has never been seen to fail. More specifically, in any energy conversion, one type of energy gets reduced; another type of energy inreases in the same amount.
The law of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. This means that the total energy in a closed system remains constant over time. By understanding this principle, scientists can predict and explain how energy behaves in various processes and systems.

That the total amount of energy in a closed system doesn't change.
Chemists and physicists say this because of the law of conservation of energy, which states that energy cannot be created or destroyed, only transformed from one form to another. This principle is based on rigorous experimental observations and mathematical calculations across various scientific fields. It underpins our understanding of the behavior of energy in the universe.
I assume you mean the law of conservation of energy, the First Law of Thermodynamics. This has been confirmed by countless experiments; no exceptions have been found. Also, countless enthusiasts have tried to build devices to violate this law; needless to say, so far they failed. Don't be one of them, wasting years of your time on something that will never work. (Search for the "Museum of Unworkable Devices", for details on this fruitless search.) The "why" is really the tricky part; nowadays, the law of conservation of energy is usually stated to be a consequence of Noether's Theorem. Her law has several aspects; but in the case of conservation of energy, this is related to the fact that physical laws don't change over time. If the conservation of energy isn't valid, then the physical laws of our Universe would change over time! However, this statement involves some advanced math. Search for Noether's Theorem for more details.
To get a complete picture of what happens with energy, you need to be aware of the two laws of Thermodynamics. The First Law is Conservation of Energy. The Second Law can be expressed in several ways; but related to energy, it basically means that useful energy is continuously being converted to unusable energy. Thus, you can indeed waste energy. The energy is still there - often in form of heat - but you can't convert it back into a useful form. So, for many practical purposes, such energy is lost.
