The law of conservation of energy states that energy can neither be created nor destroyed. What does “conservation” mean in this law?

Answer 1

Conservation in the Law of Conservation of Energy means the total amount of energy remains unchanged in an isolated system, though it can change forms or be transferred within the system.

Step-by-step explanation:

The term "conservation" in the Law of Conservation of Energy refers to the principle that the total amount of energy in an isolated system remains constant over time. This law implies that energy can change forms—for example, from potential to kinetic energy (energy of motion)—but the total energy in a system does not increase or decrease. Think of it like financial transactions: you can exchange twenty-dollar bills for coins, but the total value you have does not change. Similarly, in physical processes, energy may be transferred from one part of a system to another or converted to different forms, but the total quantity of energy in the system remains the same.

Answer 2

Sample Response: The word “conservation” refers to an amount that is unchanged. The total amount of energy in the universe remains the same. The energy in the universe is in balance.
