This video shows you how two solve two different weather balloon problems using buoyancy, buoyant force and Newton's second law of motion. In the first problem we will solve for the size of a helium filled weather balloon needed to lift a know mass. In the second problem we will solve for the mass that can be lifted by a balloon of known size.

Physics, chemistry and math all clearly explained step by step.
