NewtonianMechanics

This app is a precise 3D simulator of astrodynamics.
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.
For example, [Swing-by], [Artificial satellite], [Earth and Moon].
So you can enjoy these samples right away.
More over, you can change and save these sample data.
That is, you can create a new astrodynamics show.
On [Initial value] screen, let's select your favorite sample and press [Universe]
