We were learning in science class about forces.Then we got into groups to make a successful roller coaster. Before we can make these roller coasters we had to learn about Newton's Laws of Motion:
1. An object at rest stays in rest unless something acted on it by an outside force. An object in motion stays in motion in a straight line unless acted on by an outside force. Friction and gravity can change the force.These laws are also called The Law of Interia.
2.Acceleration of an object depends on the mass of the object and the size of the net force applied to the object.
3. When a force is applied to an object the object exerts an equal force in the opposite direction.
When we were done learning about the laws we went into are groups and decided who's going to be who. The roles were historian, lawer, design engineer, and physicist. I was the historian I learned about the tallest,fastest, and longest roller coasters in the world. The lawyer learned about safty for the park. The design engineer learned to gain momentum you have to build a first hill. The physicist learned what kind of forces make a roller coaster work, the height of the hills, and how roller coasters are tested.
My group decided to call the roller coaster Immortality. We had alot of successful roller coasters. Are cars are purple and yellow. I have some pictures of the succesful roller coaster and the failed one.
This is the failed one. It had too much speed.
This is the successful roller coaster
