Pool ball collisions. Close-up high-speed footage of a cue being used to strike a cue ball (white), which collides with a pool ball (blue) during a game of pool (pocket billiards). The blue pool ball in turn hits another pool ball (brown). This is a demonstration of the physics of elastic collisions, including Newton's Laws of Motion and conservation of momentum.
