🎈 Hot Air Balloon Buoyancy (2D)

A 2D Canvas simulation of hot-air balloon buoyancy driven by the ideal gas law and Archimedes' principle: heat the envelope, watch gas density drop below the surrounding air, and see the balloon rise or sink as buoyant force, weight and drag balance in real time.

⚙ Under the hood

A 2D Canvas simulation of hot-air balloon buoyancy driven by the ideal gas law: heat the envelope to lower the gas density below the surrounding air, and watch buoyant force, weight and drag balance in real time as the balloon rises, sinks or drifts on the wind. Live readouts show buoyant force, weight, net force, altitude, air and gas density, and vertical speed.
