Physics Project Reflection #3

Today I feel like our group has improved a lot from the last time that we have built becaue this time we have added our Rude Gholdberg half of the project and it has worked consistently. At one point in our rollercoaster, we needed the marble to end up in the tower that would make it fall into the cup and so we cut off the end of the tube and let the marble continue it's path and because of inertia, the marble continued untill it hit the inside of the tower that was waiting for it on the other end. We had trouble not only with the height of the hill that sometimes the marble didn't make it over, but also getting the cup to fall with enough weight that would also keep it balanced. We managed to work those out and we are now moving on to adding the dominoes at the end.

Roller Coaster Day 5 Relfection

Today we struggled with getting the tubing to curve down the boxes evenly, so we took down our second loop (we started off with two loops) to make sure it had enough speed to go down even though we still have no luck with so. The frustrating thing is that each day our roller coaster is different. Either it has been moved, or the tape stops working. We learned how to feel for the marble, we basically put our fingure through the track and learned that the reason why the marble keeps on going off is because the edge the box made a bump on the track that made the marble fling off. Above is a picture of our progress so far.
