Another option could be to allow the marble to fly off the end of the roller coaster and measure the distance from end of the coaster to the landing point on the ground. Damped roller coaster seats and headrests slow the transmission to the human body of changed accelerations of the roller coaster train, thus reducing jerk and higher derivatives on the rider. At the top of the hill, the train has potential energy (think of potential energy as energy . all of the "speed limit" signs were replaced with "velocity limit" signs. . In general you can calculate the force that keeps your vehicle in track: F = m v 2 r. where v is the speed of the vehicle, and r is the radius of the curve. The higher the initial point, the longer the path. (K is kinetic energy, m is mass, v is velocity) Potential energy is often thought of as stored energy.
