Final answer:
The law of conservation of energy states that energy cannot be created or destroyed, but can be converted from one form to another. This law is an important principle in physics.
Step-by-step explanation:
Conservation of energy is one of the most important laws in physics. Energy can be converted from one form to another, but the total amount of energy in the universe remains constant. This is known as the law of conservation of energy. Energy cannot be created or destroyed.
