2021-4-8  If the total energy is positive, the particle's trajectory is a hyperbola. If the total energy is zero, the particle's trajectory is a parabola. If the total energy is negative, the particle's trajectory is an ellipse. Since a circle is a degenerate ellipse, it follows that the total energy must be negative for a circular orbit.

Answers to Energy and the Skate Park - Google Docs

THE LAB ACTIVITY. Purpose – The purpose of the energy skate park simulation is to see how energy gets transferred in a real world application. In this simulation you will manipulate the skater and track to determine how it affects the energy of the system. In our skate park, there is no friction until part C, so you will not be dealing with that factor.
