Planes — Watch how four basic principles—thrust, lift, weight, and drag—unite to make airplanes soar like birds. Trains — Mighty steam engines, brawny diesel locomotives, magnetic levitating supertrains. Discover how different engines and rail systems work. Automobiles — Learn about the history of cars and find out how a gasoline engine converts potential energy into kinetic energy to get a car moving.
