PHYSICS 133 EXPERIMENT NO. 5 CONSERVATION OF LINEAR MOMENTUM IN ONE DIMENSION In this experiment, we study linear momentum conservation in one- dimensional collisions using the air track. In addition, we study the nature of the principle of action- reaction. NOTE: Perform collisions with the gliders moving SLOWLY (no more than 0.5m/s). If there is an audible "clank" (caused by a glider coming into contact with the air track) you will have introduced an external force, momentum of the gliders will not be conserved, and the equipment might be damaged. Equipment 1 air track, 1 glider with photogate, additional weighted gliders with Velcro, 1 light sensor, 1 interface box, 1 computer with timing program, rubber bands. Method By allowing two gliders to collide under varying conditions, we test the validity of several ideas: (1) The center of mass of a system initially at rest remains at rest when no external force acts on it. (2) Each action has an equal and opposite reaction (Newton's Third Law). (3) Linear momentum is conserved when external forces are negligible.
