Hot Air Balloons

The video explains the basic physics and mechanics of how hot air balloons fly. It covers the principle that hot air rises because it is less dense than cold air, and how burners are used to heat the air inside the balloon to create lift. The buoyant force must exceed the weight for the balloon to rise. The video also discusses how pilots control the balloon's altitude by adjusting the burners and rely on wind for navigation.
