Question

which statement best describes what energy transfer diagrams show?
energy can change form, but the total amount of energy stays the same.
every energy transformation results in a reduction of energy.
energy transformations result in fewer types of energy.
each type of energy can change into one other type of energy.

Explanation:

This is based on the law of conservation of energy. Energy transfer diagrams illustrate that while energy changes from one form to another (e.g., mechanical to electrical), the overall quantity of energy remains constant.

Answer:

Energy can change form, but the total amount of energy stays the same.
