My class had to do a roller coaster project. We defined words like speed which is how fast an object is moving.  The purpose of this project was to find out the physics of a roller coaster.   Newton’s First Law of Motion is an object at rest stays at rest, an object in motion stays in motion, unless an outside force acts on it. Newton’s Second Law of Motion is the rate of change of momentum is proportional to the imposed force and goes in the direction of the force.   Newton’s Third Law of Motion is an equal but opposite reaction. I was the engineer. My best friend was the historian and her friend was the design engineer. Our roller coaster constied of 3 loops and 2 hills. It was a success because we made the hills and loops not too big or small. Here is asite where you can build your own roller cosater.
