################################################### # HTML 5 Orbit Simulation # # # # Purpose: # # Attempts to provide a friendly user interface # # to quickly experiment with orbital patterns # # # # Live Demo Available At: # # http://www.johnmick.net/orbits # # # ################################################### To Calculate Force Between Two Objects, Uses Newton's Law of Gravitation: F = G* ( M * m ) / d F - Force of Attraction G - Gravitational Constant M - Mass of Earth m - Mass of Satellite d - Distance between satellite and geocenter of Earth Known Current Limitations of Simulation : - Force is only being calculated between each satellite and the center Earth object. - The satellite's do not pull on each other, nor do they pull on the Earth object - No collision detection between satellites implemented - Not accounting for many other forces which may impact a satellite orbiting earth Possible Future Plans: - Color Points on Absolute Velocities As Opposed to Comparing Against Initial Speed - Possible Gradient Solution - Remove Points After the Tail Reaches a Certain Length - Add real units to the display - Provide scaling - zooming in and out - convert physics calcs to pixels - Provide a reference of distance - radial grid or perhaps the Moon
