Science Physics Roller Coaster Post!

In science class I made a roller coaster out of tubes, and used tape and string. My coaster has a big drop then it shifts over to a loop then rolls around a stool and has another dip and then lands in a cup. I chose it because I thought it was fun, I would enjoy it if I was on it. I would probably change my place I constructed it. It was hard to build and some things got in the way like walls and boxes. My knowledge of kinetic and potential helped me with this project. In fact, I couldn't have done it without it. Because if I started down low then the marble wouldn't have enough kinetic energy to go up the hill. So I started up high to give it potential energy, which means if I put a big drop then it will give the marble speed/kinetic energy to go up the hill and loop.

I ran into a lot of problems. First my loop was too small so it made it have kinks. So I had to get clammers and put them where the kinks were. And then I put a nail in the wall at hooked a piece of string in the hose and tied it to the nail. The string kept on falling off the nail. I didn't do much to fix it. When it fell off I made the whole bigger with scissors in the tube and I would tie the string through the tube. Having a budget made it a little more intense. It kind of made it harder because I wasn't permitted to get what we needed and go! I had to keep track of how much money things were and what I bought. It took time off of building the coaster. But I feel like it did keep us organized because if we got what we needed then I would probably have a big mess. Friction had an impact because when I didn't have enough kinetic energy and add friction on to that I had to raise the hill higher and that would change the rest of the coaster. Argh, friction! I had to make a couple modifications. First the marble didn't have enough kinetic energy to go up the loop. So I made the loop smaller and it didn't get any kinks so it was a success. Then, the other mishap was the marble just flew out of the hose. So I put a cup to have it end and not go all over the place. So in the end it all worked out fine and dandy!

Here is my prezitation of my project.
