As you can see, this example simulates several "particles", in this case "watermolecules" in a drop of water in space (no g-force).
Each particle has certain properties such as a velocity, mass and force. These properties can be looked up in the QDockWidget on the right.
At the beginning of the simulation all particles have no velocity at all. I will now start the simulation. Lets see how the different forces effect the particles. I will stop the simulation after about two seconds.
As you could see: the particles moved. Everything is calculated in realtime based on the law of physics. The velocity is now indicated with a blue arrow, the red arrow represents the acceleration.
Thank you for your attention. Please post comments to this video or this blog.
