In science class we learned about roller coasters and all the things that aply to making a roller coaster. The reason that roller coasters work is through Neton's Three Laws of Motion. The first law of motion is that an objet that is at rest stays at rest unlees an outside forces act on it, such as friction and a object in motion stays in motion stays in motion unless an outside force acts on it. This could also be called the law of inertia. The second law is acciluration of an object depends on mass of the object and its size of the net force applied . The third law of motion is when a force is applied to an object  the object exerts an equal force in the opposite direction. Momentum is the force needed stop a moving object.

 After we learnd about the roller coasters we were asigned jobs. The jobs were Historian, Physicist, Design Engineer, and the Lawyer. THe Historian was my job so I would gather info on how roller coasters started and what is the tallest roller coaster. The Physicist would gather info on what forces would be supplied on a roller coaster and how they would test roller coasters. The Design Engineer would figure out what materials are used to making a coaster. The Lawyer would figure out what laws were in amusment parks and how many times does a roller coaster get check in a day.

In our group we had many failures with the roller coasters but we have also had some sucesses.This is an image of one of our susessful coasters.This was a succes because the hills were pefect hights and the loops. 

This is a image of one of our fail coasters. It failed because the height of the second hill was to great.

If you want to build a coaster click here. My team’s successful coaster was called Differ of Gravity. We got the name because we just were thinking of cool names. I like our coaster and I hope you will build a cool coaster to.
