Motion Lab

Today we did a lab on motion. In the lab there was a machine that emitted sound and checked how long it took for the sound to return. Then the computer will imput the data and show you, your current velocity or displacement. There were several graphs that we were suppose to match. We each had several tries, and my teammates and I were able to save the ones that were our best match. After the lab we also have to do a lab report which will be assigned tomorrow.
Here are some of the graphs we walked:
