Abstract: The collision of two glass spheres on the plain is recorded and analyzed by the video analysis software Tracker. By measuring the displacement and velocity of the collision spheres, the problem of measuring two or more objects in two-dimensional motion at the same time is resolved. Consequently, the law of conservation of mo- mentum can be verified and the coefficient of restitution can be calculated in this experiment of collision.

Key words: video analysis, Tracker, collision, conservation of momentum, coefficient of restitution
