G is a Gravitation simulator designed for iPad / iPhone.
Check the demo video at http://www.gravityApp.info
G allows you to quickly experiment the effects of the Universal Gravitation by adding bodies into a simulation, seeing how they react to each other in real time, all in a true multitouch environment. G offers a vast universe to add your bodies into, potentially allowing you to create stable planetary systems, binary star systems, and other multiple-body complex systems.
G is very simple to use. When you first start it, you are presented with the solar system. The Sun and all planets from Mercury to Uranus are added to the simulation, including the Earth's Moon.
First, get familiar with how to navigate G's Universe.
- Drag on empty space to pan around the universe
- Pinch (two fingers) to zoom in and out the Universe.
- Tap on a body to select it, making the camera follow it.
You can then start interacting with the system, by adding new bodies, modifying or deleting the existing ones.
- Double-tap on empty space to create a body.
- Drag after double- tap to set the new body's initial velocity.
- Drag an existing body to relocate it.
- Double-tap on an existing body to set a new velocity.
The placement, the mass and the initial velocity of the newly added bodies will dictate how
