Steven, I was puzzled because I took your bouncing ball metaphor literally. Thanks David and Robert. I guess the graph approaches the path described by bouncing ball as the ellipse becomes flatter. harry On Thu, Mar 1, 2012 at 12:01 PM, David Roberson dlrober...@aol.com wrote: The orbital

I have another update concerning my on-going theoretical research into characteristics of celestial mechanic algorithms. Last Wednesday I mentioned the fact that another way to graph an elliptical orbit (an orbit that obeys Kepler's 1st, 2nd, and 3rd laws) would be to plot the satellite's

Speed increases as the satellite orbits closer to its parent, and slows as the orbit is extended. As the x-axis is a linear representation of time, the changes in speed during orbit serve to compress the wave troughs and expand the wave peaks. Thus the wave resembles more of a bouncing ball

The orbital distance is changing faster when the object is closest to the earth which would tend to look like a quick bounce. At the far spacing, the change in orbital distance is slower depending upon the elliptical shape. The mathematical equation defining the function of orbital distance
