This is my second gravity simulator. Its just like my first one, exept the ball bounces, and moves forward, and graphs rainbow parabolas as it moves. The forward motion is not accurate (its only there for the purpose of making rainbow parabolas), but everything else is. Just click drop to start it. There are bright colors Go to: https://scratch.mit.edu/projects/196403341/ for my other gravity simulator. Third (and best) Gravity sim: https://scratch.mit.edu/projects/196493498/
