Physics Project Reflection #4

Final Physics Project Reflection

Finally, all our hard work has paid off. We presented our roller coaster to the public and I believe it was a great success. We learned a lot during this unit, we learned about Newton's laws of motion, G-forces, and energy, we also learned a little bit of engineering from building the roller coaster. I liked learning about all of Newton's laws and I also liked to learn about physics in general. We could have smoothed out our roller coaster by making the helix coil on the third building a little bit better working, but other than that, I believe we did a great job on our roller coaster. I felt a lot of pride when I heard little kids whisper our roller coasters name associated with the word "Awesome".

I feel very pleased with our groups progress on the roller coaster. We have finished most of the hard parts and we have made it look nice by spray painting the buildings black and tying string to the pipes for support so that the pipes don't lean to one side. Inertia has affected our building process a lot. It is very hard to control the marble during the turns, when the marble is going through a turn, it wants to keep going forward because of inertia, but the track turns so if the wall isn't big enough the marble just goes straight through and flies off the track. We have to make the track turn gradually, it cannot be sudden otherwise the marble would fly off the track because it wants to keep going forward. It also affected our building progress when the pipes make a bump on the track. The track is soft so the pipes penetrates into the material and makes a bump, when the marble passes through the bumps it flies, so we had to make sure there were no bumps on the track. The turns have been very frustrating because the marble would always find a way to fly off the track even though we have made the walls of the track bigger and made the turn more gradual. Our group has persevered and we listened to each other's ideas to make the roller coaster work better and to look nicer.

Our project has gone quite well so far, we have finished adjusting the first loop and we have more than enough materials to finish the whole project. It was really frustrating to adjust the loop and it took us an entire hour of work time to get it to work perfectly. The problem was that the tubing made a dent when it was placed on top of the PVC pipe and it made the marble go flying when it passed the dent, so to fix that we covered the hole with a piece of cardboard and now it seems to work fine. We plan to finish the next stage of the roller coaster by the end of next class, which is to make the coaster go round and inside, then out of the triangular building ( building on the left side of the photo ).
