Momentum Objective To investigate the Law of Conservation of Momentum by analyzing one-dimensional elastic and inelastic collisions. Introduction Momentum is a vector property of all moving bodies. Although momentum does not cause physical phenomena to occur, it is a physical variable which can help us to understand and predict many events. Phenomena which involve explosions or collisions-often difficult to analyze using Newton's Laws can be readily described using the concept of momentum. As you know, the linear momentum of a body is defined as the product of its mass and its velocity. Since velocity is a vector, so is momentum. In this experiment we restrict ourselves to motion in one dimension, thus simplifying the analysis. The true usefulness of the momentum concept is found in the Law of Conservation of Momentum which states: 18 Experiment Thus, when two or more objects collide, the total momentum of all the objects before the collision (paying attention to sign conventions!) will equal the total momentum of all the objects after the collision. The velocities of the objects will not, however, be conserved. Apparatus "In the absence of external forces, the total momentum of a system before some event is equal to the total momentum after the event." In this experiment you will study two types of collisions. In an elastic collision, the objects bounce apart after the collision. In an inelastic collision, they stick together after the collision. In both cases, momentum will be conserved. However, the kinetic energy of the objects may not be conserved. The air track is used to eliminate (or greatly reduce) external forces. Read on! .
