Today we just worked on our roller coaster projects. The objectives were to finish our technical manual and plan whether we were going to build a model. We also prepped for our presentation. Me and my partner had catching up to do, so we were just started working on our technical manual.

Our technical Manuel required the following information: Circular Motion: Centripetal force: the force, acting upon a body moving along a curved path that is directed toward the center of curvature of the path and constrains the body to the path.

Energy (Kinetic and Potential): Ke= the energy of a body or a system with respect to the motion of the body or of the particles in the system. Pe= the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.

Safety Information on the ride (Had to have less then 5 g’s

Projectile Motion:Projectile motion refers to the motion of an object projected into the air at an angle

Our presentation had to show a model of our ride and explain key facts on it. We also had to sell our ride so that potential buyers would be interested. It has to be two minutes.
