EXPERIMENT 6 Introduction to One-dimensional Collisions Elastic and Inelastic Collisions Apparatus A one-dimensional air track, an air supply, two carts, a photogate timing circuit (including two photogates) and an analytical balance will be used. Figure 1 below is a picture of the air track set up. A photogate, an air track cart and a cart passing through a photogate are shown in Figures 2a, 2b and 2c, respectively. Figure 1 Figure 2a Figure 2b Figure 2c

Theory The following two experiments deal with two different types of one-dimensional collisions. Below is a discussion of the principles and equations that will be used in analyzing these collisions. For a single particle, momentum is defined as the product of the mass and the velocity of the particle: p =m v . (1) Momentum is a vector quantity, making its direction a necessary part of the data. For example for the one-dimensional case the momentum would have a direction in either the +x direction or the -x direction. For a system of more than one particle, the
