Exercise 2 Conservation of Momentum for Elastic Collisions In this experiment you will calculate the momentum of marbles before and after elastic collisions to verify the law of Conservation of Momentum. Procedure Part 1: Setup Gather the digital scale, masking tape, measuring tape, stopwatch, and materials set aside from Exercise 1. Put on the safety goggles. Check the setup of the ruler and wooden board to make sure nothing has moved since you completed Exercise 1. Note: View the video "Using the Digital Scale" before continuing the procedures. If needed, a descriptive text transcript is available. Using the Digital Scale This video shows how to use a digital scale Use the digital scale to measure the mass of each marble in the conservation of momentum assembly. Record the mass to .01 grams in Data Table 2. Use the measuring tape to measure distances of 0.15 and 0.25 m on the wooden board and mark with tape so the locations are easily viewed from the side as shown in Figure 7. Figure caption is an adequate description of the image. Figure 7. Tape marking distance of 0.15 m and 0.25 m from ruler end of wooden board. Note that tape is
