G [iPad, iPhone]


G is a Gravitation simulator designed for iPad /iPhone created by Oriol Ferrer Mesià. G allows you to quickly experiment the effects of the Universal Gravitation by adding bodies into the simulation, seeing how they react to each other in real time.

The app allows you can change the speed and the value of the Gravitational Constant which factors how strongly each body attracts other bodies. The placement, the mass and the initial velocity of the newly added bodies will dictate how “successful” your system will be. Bodies will collide in G so if one of your bodies hits another body, they will merge into a single body. The physics implemented in G follow “Newton’s Laws of Universal Gravitation“, which states that every massive particle in the universe attracts every other massive particle with a force which is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Luckily you don’t have to worry about the math, just click away and create your play in your own universe. Highly meditative.

made with openFrameworks.

  • First associated with the G-spot, huh :) this Gravitation app seems though to be really not bad. I think it will be helpful even for children learning astromomy or physics. And I like the interface and the idea on the whole.

    Have it for iPhone. There is a problem. I created a star/body and sent it through the solar system. I had the velocity of it around 240. The mass on the other hand, was ENORMOUS. I was tracking a planet as it headed towards it, it slingshotted past and left the system at OVER 200,000 VELOCITY! The problem? I think I am light years away from the system, and I cant get back. While loading a preset, I imagine it loads the planets, but I am still in the same location (light years away). Needs to be a reset to 0,0 on the axis.

    Think there are some flaws in the physics representation. I have a body traveling at over 1.97billion KM per second. The speed of light is ~300,000km per sec. Just sayin.

  • Great information for students !

  • It is just another proof that Apple gadgets can replace the pcs.
