Physics 105

April 21, 2003

Today we will continue analyzing our collision experiments. Each person will analyze the 3 collisions in which they were involved. In the analysis you should focus on the following questions:

- determine the momenta of the carts (+students) before and after the collision
- determine the kinetic energies of the carts (+students) before and after the collision

We will generate a table with details of each of the collision. Since each collision is analyzed by 2 students independently, we will be able to estimate the accuracy of the results (or spot errors). A number of collisions will be analyzed by the entire class to get a firm estimate of the errors in our procedure.

The results of the analyses will be compared with the measured deformation and can types, and we should focus on the following issues:

- determine the correlation between the total change in the kinetic energy in the collision and the deformation of the cans.
- determine the correlation between the change in the momentum of a cart the deformation of the cans on that cart.
