Orbiting Particles

This code creates up to 10 particles. Each particle has a random mass, initial speed, position, and initial direction. Each particle will then interact with the other particles on the screen and all will adjust positions, speed, and direction according to the gravitational forces affecting it. By modifying the code to create customized particles instead of randomly generated particles the user can: -Create a solar system with orbiting planets around a sun. -Change the limit set to maximum gravity and watch a 'slingshot' effect. -Add friction to the particles and watch as several particles collect together. (to do these, you can modify the presets in the code, or create your own) Three new objects are created: VectorPoint, Vector, and Particle. A particle contains a Vector, which uses a VectorPoint. Beginners can see how to set up their own custom objects, and how to use an object as a property of another object.
