the law of ? of energy states that energy can never be destroyed or created
Law of conservation of energy.
The law you are referring to is called the Law of Conservation of Energy. This fundamental principle states that energy is conserved in any given system, meaning that it cannot be created or destroyed, but it can only be converted from one form to another.
To understand how to arrive at this answer, you can follow these steps:
Step 1: Read and understand the question.
Step 2: Recognize that the question is asking for a law related to energy that states it cannot be destroyed or created.
Step 3: Identify the principle that aligns with the given description. In this case, it is the Law of Conservation of Energy.
Step 4: State the answer clearly as the Law of Conservation of Energy, which states that energy can never be destroyed or created, only transformed from one form to another.
