Hit play, and watch the rocket fall into the "Moon black hole". Press "d" to slow down the passage of time. Press "s" to speed the passage of time up.
This is based on the Orbital Simulator. It demonstrates that the "slingshot effect", as seen in the Orbital Simulator, is only a numerical artifact. To see this, first try running the game at normal speed. Don't use the rockets - just watch the rocket fall into the Moon's "black hole"; it comes shooting out the way it came in, at a velocity of 57. That's the (fake) slingshot effect. Now run the simulation again, only this time, slow the speed down by a factor of 4 (press "d" twice). It'll take 4 times as long to run, and there will be 4 times as many "waypoints" calculated. This time, the results come out very different - and slower. If you once again run it, this time slowed down by a factor of 128, it comes out very different still - faster this time. To see how the real slingshot effect works, see my Slingshot Effect project: http://scratch.mit.edu/projects/10680144/. The real slingshot effect requires a moving planet.
