We have been working on our conservation of momentum experiment. At this point, each group completed THREE collisions. Since they were sticky, we call them "perfectly inelastic collisions". Each collision involved ONE car moving before they crashed. After the collision, they stuck together and moved off. We only had to measure ONE speed before and ONE speed afterwards.
For the first collision, the two cars had the same mass. For the second collision, the car moving before carried the extra mass. For the third collision, the car that started at rest had the extra mass.
HOMEWORK: You need to start writing about the experiment. It may be challenging for you to write, but it is very important that you try. Below are some questions that you should answer in your paper. The paper should be about a page long, and it would be a good idea for you to TYPE the paper, so that we can use it later.
QUESTION- Did your data support that momentum is conserved?
Helpful smaller questions:
What did you do to get your measurements (how did you do the experiment?)
What were your results for each collision (include your values for total momentum before and after for all three collisions)
Explain how close the momentum values are (use subtraction to show how close they are)
Explain why not perfectly equal (why aren't the results perfect?)
