Roller Coaster

We made roller coasters in class today to demonstrate Newtons Three Laws of Physics. Our roller coaster was built with paper towel tubes and tape. It had three hills, a roller coaster aspect, and used a marble as the cart. While building our roller coaster we had to factor in friction, force, acceleration, and velocity. we started the roller coaster with a tall tube so it would have more time to accelerate to a greater velocity. We also tried to minimize the upward movement of the marble because the friction would slow it down. We had the marble moving down a lot so it would be going fast enough to complete the hills. Our roller coaster worked well after we finished construction. We learned a lot and had fun building this project.
