Collisions are ubiquitous in the nature. They occur at microscopic levels between elementary particles as well as at grander scales when galaxies collide, merge and scatter. In all such processes, the linear momentum of the complete system is always conserved. In this experiment, we will study the collision of two objects in a controlled setup using the video motion tracking technique. We will show that the law of conservation of momentum holds in 2-D collisions and determine the type of collision through quantitative analysis.
