Lab: Conservation of Momentum. The goal of the lab today is to look at collision between the the dynamics carts and establish whether momentum is conserved or not. You will set up six different collision that you will make qualitative observations about the collisions. Once finished, you will then use the photogates to make quantitative observations of two collisions. When finished you will determine if momentum was truly conserved based on your observations and data.
We have only four tracks that can be used to collect data, so we will have to share. Take turns using the tracks. Set the carts on the track, produce the collision, and make your observations, collect the data, and let the next group go. As a group records their observation, another can set-up and produce their collisions.
