Which statement about energy conservation is true?

Energy conservation means the total amount of energy in a closed system stays the same, even though energy can change form or move between objects. The statement that energy cannot be created or destroyed, only transformed into another type or transferred, is the correct idea because real processes simply shuffle energy around or change its form. For example, a falling object converts potential energy into kinetic energy, a lamp changes electrical energy into light and heat, and plants store chemical energy from sunlight for later use. The total energy counted in the system remains constant through these transformations. The other ideas—energy appearing from nothing, energy disappearing, or energy not being transferable—don’t fit with how energy actually behaves.
