Final answer:
Energy conversion, also known as Energy transfer, is the term describing the transformation of energy from one form to another in accordance with the Law of Conservation of Energy.
Step-by-step explanation:
The term used to describe the transformation of energy from one form into another is Energy conversion or Energy transfer. This concept is fundamentally linked to the Law of Conservation of Energy, which states that while energy can change forms, it cannot be created or destroyed. For instance, kinetic energy converting into potential energy, and vice versa, or electrical energy transforming into light and heat energy, are all examples of energy conversion.
