NewtonianMechanicsLight vs neural networks for xy Usage & Stats

This app is a precise 3D simulator of astrodynamics.(Light version : disable to save user date) By using Newton's motion equation and Law of universal gravitation, with the attributes of heavenly bodies, such as mass, radius, position and velocity, this app can simulate their behavior afterwords. We prepared some samples. So you can enjoy these samples right away. More over, you can change these sample data. That is, you can create a new astrodynamics show. On [Main] screen, let's select your favorite sample and press [Universe]
