My Roller Coaster

The purpose of this project was to learn about roller coasters and their history and physics. The three laws of motion are: 1.An object at rest will stay at rest unless it is acted on  by an unbalanced force. An object in motion stays in motion with the same speed and direction unless it is actedon by an unbalanced force. This law is often called the law of inertia. 2.Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). 3.For every action there is an equal and opposite re-action.

There were four jobs. The lawyer, the design engineer, the physicist, and the historian. I was the historian. I had to find out the history of rollercoasters. I also had to find out the fastest, longest, tallest, and the biggest. Ryan was the physicist. Natasha was the design engineer. Drew was the lawyer.

The outcome of this project was to know the history, the laws, the physics, and the design of rollercoasters. The reason my first roller coaster failed is because it had to much speed and so it crashed. Here is a picture of the coaster that failed.

We called our coaster "The Abominable Taco".

The reason my second roller coaster was a success was because it had the right amount of speed. Here is a picture of the coaster that was a success.
