Newton's Cannonball Simulator

The idea of this game comes from

Newton's cannonball:

Thanks, Newton.

The result of the calculation is only an approximate value !

============================================================

Try to input these values and have fun!

Planet	Planet value	Mass	Diameter
Mercury	107.9	330.22	487.8
Venus	169.5	4869	1210.36
Earth	173.7	5965	1275.6
Mars	127.5	642.19	679.4
Jupiter	553	1900000	14298.7

How to play:

1. Press F to fire.
2. Enter the number and press Enter key to confirm.
3. Click restart button to restart the scene.
4. Click fixed button to switch camera model. In fixed model, press the zoom button to zoom in and out. In free model,press WASD to move, and hold right mouse button to change perspective.
5. Click clear button to clear all bullet in the scene
6. Click info button to show this page.

Value introduce:

1.The planet value is generated by algorithm criticism, in which the default is earth (173.7). Please click the question mark button beside it for other planet value. It is only used to control the correct circular motion of the bullet without affecting the calculation results.

2.When the gravitational constant (G) value is the default value, the planet mass (M) fills the 10^-21 times of the original value, unit is kg.

3.Planet diameter (R*2) is 0.1 times the original value, unit is km.

These data can be found on Wikipedia!
