These labs will take about three days to complete. Tuesday will be preparing/practicing. Wednesday will be completing Part 2 and 3. Thursday will be sharing your trends/conclusions with the class, where we will look for overall trends/conclusions.

1. Prelab discussion (much yesterday)
2. Part 1: Qualitative construction of momentum
3. Part 2: Collision of Carts
4. Part 3: “Explosion” of Carts
5. Postlab discussion

Part 2: Collision of Carts

You will be provided with two carts and various masses. You will need to measure the speed of the carts right before they collide and right after they collide.

Working with your group (record all in your lab book):

1. Develop a method of measuring/calculating the velocity of two carts right before and after they collide.
   • Practice with your method until you are confident you can accurately measure the needed velocities.
2. Determine the uncertainty in each of your measurements.
3. Plan out at least four different types of collisions. This may involve
   • Initial directions
   • Masses
4. Develop a data table to record your data for all your variations.
5. Run your trials.
6. Analyze your data
7. Present trends in a reflection section.

Part 3: Explosions

Explosions are defined as interactions where the initial velocity of each cart is zero.

Repeat the steps you used for Part 2
