Soaring Straws

The lab soaring straws told me a lot about the relationship between elastic potential energy and gravitational potential energy. On our graph when the elastic potential energy was risen which was the stretch of the rubber band, the gravitational potential energy was also risen. This is because the further the rubber band was stretched was the higher that it went. For example, when we launched the rubber band from a two centimeter stretch, the straws gravitational potential energy was 2.943 millijoules. When we launched it from a three centimeter stretch it's G.P.E was 5.886 millijoules. From the stretch of the rubber band the height doubled. The G.P.E was the height that the straw went. That is the relationship between gravitational potential energy and elastic potential energy.

During our data collection there were a couple of errors that happened. First, when we were measuring our measurments they were not exact. Also, since we did it over two different days we got different launchers which mad different results. Ways to enhance the lab was to make every launcher the same. Some launchers shot very high but some did not. Usually, the thick rubber bands shot lower than the skinny ones. Also, we could have our measurments a lot more accurate because we could have made the ruler more steady and watch the hieght of the straw better. Finally, that is what the lab soaring straws taught me and how it can be a lot better.
