In science class we were assigned a project to build a roller coaster out of paper. The roller coaster had to have three turns,one loop and two hills. Building the roller coaster wasn’t very hard. The reason we built it was to see if the potential energy and the velocity change when we roll a marble down it. While making the roller coaster the main problem we had was with the loop because it wouldn’t roll all the way around. It took a little bit for us to adjust it to work but we figured it out.
When our roller coaster was finished we took measurements from all of the roller coasters. the velocity of the marble on my teams roller coaster decreased the less so my teams roller coaster won.
