Roller Coaster Velocity Report for 8th Grade Science

The performance of our roller coaster, The Gunslinger, was based on the ability to provide an example of Newton’s First Law of Motion, which states; an object in motion stays in motion while an object at rest stays at rest unless acted upon by an unbalanced force. Our design shows that The Gunslinger achieves potential and kinetic energy through gravity and friction caused from the momentum that the acceleration provides.

First we start off with acceleration, which is the increase of speed or velocity. In our roller coaster acceleration happens as you move down the slope, through the loop, and around the curve. Negative acceleration happens as you move up the loop, before the hill and right before the exit path. In order for negative acceleration to happen we need friction. Friction is the rubbing of one object or surface against another. Friction is what makes the object slow down as it moves up the loop and up the hill. Gravity is the natural force or attraction between any two massive bodies. Gravity is what pulls the object down the slope at the beginning of the roller coaster.

Our design of the roller coaster also shows that it is able to accomplish potential and kinetic energy as momentum occurs all through out. Momentum is a measure of the motion of a body equal to the product of its mass and velocity. Therefore, momentum occurs as the object moves down the slope in the beginning, right before the curve, after the curve before the hill and right after the hill before the exit path. In other words, all through out the roller coaster. Potential energy is the energy of a particle or system of particles derived from position, or condition, rather than motion. In our design potential energy occurs at the top of the loop, on the way down and at the top of hill right before the exit path. Kinetic energy is the energy possessed by a body because of its motion. As soon as the roller coaster...
