Roller Coaster Web Quest

In science class we are learning about forces and had to come up with a roller coaster and build it online. We also learned about Newton's Three Laws of Motion. The first Law of Motion states that 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. The Second Law of Motion states that acceleration of an object depends on the mass of the object and the size of the net force applied. The net force will increase and the acceleration will increase. The Third Law of Motion states that when a force is applied to an object, the object exerts in an equal force in the opposite direction.

In each group we had a physicist, a lawyer, a historian and a design engineer. The physicist would estimate the heights of the hills and the number of loops in the roller coaster. Velocity and momentum usually are a big part of the job. The lawyer would find out the laws and regulations for the roller coaster. The historian would find the history of the roller coaster and how roller coasters have changed. I was the design engineer. The design engineer would find out the materials you would use to build the roller coaster. The design engineer would also look at the terrain, surrounding rides, power lines, roads, lakes, and trees. While learning this I also learned that your inertia keeps you in the roller coaster car. Especially while in a loop.

When my team finally finished the project our roller coaster was a success, but we had a little trouble along the way.

This is my team's roller coaster design when it failed in the simulator. The reason it failed was because after the last hill it didn't have enough of a hill to stop the coaster car from moving. The final name our team chose for our roller coaster was Pretzel Twist. If you would like to make your own roller coaster creation, click here.
