For the past week in Science, we have been working on building roller-coasters or skate-parks out of certain materials given, such as paper tubes, tape, straws, and paper cups. My group is creating a roller-coaster. The requirements are to have four hills and bends. We are doing this project to put Newton's laws to the test. By looking at the speed of the marble, we can figure out the highest points of kinetic and potential energy. For example, our highest point of potential energy, or energy that will be used for kinetic energy, is at the very beginning of the ride because it will be pushed down the ride, but it hasn't been yet. Our highest point of kinetic energy was in the middle of one of our fastest hills because it had the highest speed and the most energy.When I went online to find more information on Newton's Laws, I realized that all three are on seperate topics, but they relate in a certain way. They all relate to the world around us and they teach us about speed and velocity. I feel that this project is a fun and efficient way to have us learn about physics and Newton's Laws.
