Roller Coaster Project

Our 6th grade class did a roller coaster project in science class. We did the project to see how Newton's Law of Motion works with roller coasters. These are Newton's Laws of Motion: 1st law- An objet atrest stays at rest unless acted on by an outside force. It is also the same as the Law of Inertia. An object in motion stays in motion in a straight line unless acted on by an outside force.

2nd law-Acceleration of an object depends on the mass of the object. The size of the of the net force increases and acceleration increases.

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

The project has four roles. Those roles were the lawyer, the physist, the design enginer, and the historian. The lawyer had to research the safties and law suites for roller coasters. I was the physist. I had to research what kind of energy a roller coaster uses to make it work. I found that potential energy is the same as stored energy. You find potential energy when you're going up the hills. Kinetic energy is the energy you feel going down hill. It releases the potential energy that was stored up the hill. Friction is used to help slow down the coaster to a complete stop. The design enginer researched what roller coasters were made up back then and now. The historian had to research where roller coasters originated from and the frist roller coaster, the tallest one, etc.

This is one of my roller coasters that failed. It didn't work because it didn't have enough speed to get past the first  loop.

This is a roller coaster that was a success! It worked because it was fast enough to go through all the loops but not too much to crash.

The name of our roller coaster is the "Pretzel Twist". We had other ideas, but it was close to lunch and we were all hungry, so someone ended up says "How about we call it the 'Pretzel Twist'!" We all agreed and that's how we got the name. If you want to make your own roller coaster click here.
