Conservation of Energy

The video explains the concept of energy conversion and the law of conservation of energy. It uses examples like the human body, cars, and roller coasters to illustrate how energy is transformed from one form to another without being created or destroyed. In closed systems, energy remains constant, merely changing forms, as demonstrated by a car's engine and a roller coaster's motion.
