Science Experiment on Ramps

In science class we are studying physics. I am in a group with Ruby and Charmaine. Our individual groups chose a project that they wanted to do to learn more about physics. Our group conducted an experiment based on execration. We used adjustable science tables to form a 20 degree ramps on which the car would be let go from. We put Ruby at the four meter mark and me at the two meter mark. We would say ready, Charmaine would say set, and we would say go. Charmaine would let go of the car, and we would start the timer and then stop it once the car passed us or got to us. We did this five times, and then put me at the one meter mark, and put Ruby at the three meter mark. Once we finished that we wrote all the times down, averaged them. After we got all the average times we took them and took the difference between the averages and made a estimate of when the car would stop. The answer we came out showed that the car would stop at 9.7 meter. And while we were doing the averages and the part where mathematics comes in we notice that from one meter to two meters the speed positively execrated, but it slowly went down, and that was how we found where it would stop. It was very confusing at first as to how we were going to find out when it would stop. But as we experimented it all came clear to us. I really learned a lot about execration and speed throughout this experiment and I hope to be able to conduct a lot more experiments throughout the year.
