At the top of a hill, a roller coaster has Potential Energy. At the bottom, it has Kinetic Energy. If we set them equal to each other, then we can find the velocity/speed from the height of the hill. But is this true? I put this to the test and try to derive the gravitational constant of acceleration of 9.81 meters per second squared from roller coaster heights and speeds only. All data was taken from rcdb.com. I got pretty close but I also explain the effects of friction on slowing down a roller coaster on the drop.
