Simplified gravitation simulation. The Eart planet is fixed. Movement is calculated as sum of 3 vectors (initial speed, gravitation, centrifugal force) Uses Gravitation Konst G; F=(G*m1*m2)/r^2 and centrifugal force with F=(m*v^2)r. You can insert different masses and initial speed / angle at the code. Simulations like this are used to calculate the possibiliy of an asteroid impact. (use shift+green Flag for turbo mod)
