The statement that best explains the changes in available energy is:
Energy constantly changes from one form to another.
This reflects the principle of conservation of energy, which states that while the total energy remains constant, it can change between different forms (e.g., kinetic, potential, thermal, etc.), affecting its availability for doing work.
