This year our 6th class did a roller coaster project. After we learned about Newton's Laws of Motion we started the roller coaster project. These are the Laws of Motion: 1st Law - An object at rest stays at rest unless  acted on by an outside force. An object in motion stays in motion in a straight line unless acted on by an outside force. This law is also known as the Law of Interia.     2nd Law-  Acceleration of an object depends on mass of the object. The size of net force increases and acceleration increases.

 3rd Law- When a force is applied to an object the object experts an equal force in the opposite direction.

                  The project we had as a group was four roles. The four roles were historian, physist, design engineer, and the lawyer. The historian found out about the history of roller coasters. The physist looked up the physics that were in making a roller coaster. The design engineer looked up the materials and things to make a roller coaster. The lawyer looked up the safety rules and the things that you need in a park to make it safe. I was the historian and I found out the rollercoaster that were the biggest, fastest, and tallest.

After our group was finished we went on a coaster creator and we designed roller coasters. Some of them failed but one of ours worked. The ones that failed and to much energy and momentum so it crashed. I did my own coasters one failed because it had to much speed so it did stop then I had one success.Our roller coaster was called Pretzel Twist.

This is the failed one.

This is one our group did that succeded.
