Before merging this change into master, it would be good to do some side by side testing of the two algorithms and see if there are any differences in the sim behavior.\r\n\r\nThe old algorithm can be found here: http://www.colorado.edu/physics/phet/dev/html/gravity-and-orbits/1.0.0-dev.20/gravity-and-orbits_en.html\r\n\r\nThe new one here: http://www.colorado.edu/physics/phet/dev/html/gravity-and-orbits/1.0.0-experimental.1/gravity-and-orbits_en.html\r\n\r\nTesting on iPad will reveal that the new one gets much better performance.\r\n\r\nAssigning to @ariel-phet for prioritization."}}
