Talking about energy is tricky because everyday words can also have specialized scientific meanings. Through the process of defining key terms like "power," "work," and even "energy" itself, this program uses a roller coaster, a harmless train wreck, ice -skaters, a boulder, a human cannonball, night -vision goggles, and a supernova to introduce students to kinetic and potential energy, electrical energy, chemical energy, nuclear energy, and conduction, convection, and radiation of heat.
