This NASA video segment explains the four main ways that atoms, molecules and particles move in a fluid. Viewers learn what sedimentation, buoyancy-driven convection, diffusion, and capillarity are and how gravity impacts each of these processes differently. The segment also discusses the reason it is important for fluid physicists to perform their experiments in a microgravity environment. Laboratory demonstrations support the presentation.
