Today when we came in to class, we were to finish presenting our roller coaster projects. These projects had to incorporate projectile motion, as well as all of the physics, and had to be convincing for someone to not only want to ride your ride, but for also the buyers of the rides, to want to build your ride. There were a few presentations, as well as Karley’s and mine. Ours was the Hangman’s Revenge. This was based off of a ferries wheel that not only rotated around, but also swung. In included the projectile motion portion of our ride by the way it is started. The other groups that had gone did mostly water rides. All of the presentations were nice to watch, and the rides were then evaluated by all of the classmates. We were graded overall by Mr. Manning, who gave us a grade based on time, technical manual, and other aspects of our presentation that he was looking for. We each graded them on their model, the ride safety, overall ride, and the physics. All of these areas were out of a total 50 points. After everyone presents, Mr. Manning will average all of the scores that were given for each of the presentations, and pick the one that has the highest “grade” from the class. This is the one what, if this were real, it would be built. We did not have any homework because we just had all of the presentations. We ran out of time, so there will be more presentations tomorrow. They are all graded the same, and everyone presents.
