Science Reflection on Ramps
In science class we are working on physics project, learning about ramps and speed. I was in a group with Charmaine and Brianna. We were working on a project about acceleration, and how long it would take for a car going down a twenty degree ramp to come to a complete stop. We are also wanting to measure the acceleration of a car when on an incline. To measure the angle we used a protractor. We had a marker at every meter so, that we could see the car slowing down. Brianna timed at the two meter mark with a stop watch and when the car passed the line she would stop it. I was timing the four meter mark. We would say ready, then Charmaine would say set, then we would say go. Charmaine would release the car and then we time each run. We also timed at the one meter mark and three meter mark. The next step was to find the average of all the time, when we where all done with finding the averages, I tried to find out how long it would take for the car to come to a complete stop. It was really challenging because we had never learned the formula, so I had no idea how I was going to figure it out, but in the end Carwai showed me how to really do it . Surprisingly I was only off by .2 from the real answer. In the end we found out that a car going down a twenty degree slant would come to a complete stop when it reached 9.7 meters. I really enjoyed doing this experiment. I think I have learned a lot about physics and equations.
