All you need to simulate our physical World.

The physics simulator PHYSIKI is a computer program designed to simulate Newtonian dynamic physical systems. It accepts user-defined equations for fields and forces. Displays user defined particles in a 3 dimensional space. These particles interact with any number of other particles through the predefined force and field equations.
It displays force and velocity vectors for the particles as they move in 3 dimensions. Graphs of particle parameters can be displayed as the simulation proceeds, or can be stored in a file for further manipulation
Simulate from Newtonian to chaotic systems.

PARTICLE
The word particle is used by the simulation program to represent the abstraction of a point mass. An electron, a stone a satellite can be thought as point masses in the right context. Any number of particles can be created edited or deleted, limited only by the computer resources.
QUANTITY
A quantity in the simulation program is referring to a physical quantity as charge or mass. One or more quantities can be given to a particle. The special quantity mass is given automatic to every particle while it is been created. You can create hypothetical quantities too. You specify a quantity when a particle field or force is defined.
FIELD
Field in the simulation program is referring to a physical field. The electric field inside a capacitor can be represented as a field by the simulation program.
When defining a field you specify its Cartesian force components and the name of a quantity which if a particle has it will react to the field.
FORCE
Force in the simulation program is referring to a physical force. The gravitational force or any force between physical particles can be represented as a force by the simulation program.
When defining a force you specify its Cartesian components and the name of a quantity that is the carrier of the force.
For two particles to exert a particular force to each other they must have the carrier quantity the specific force expects them to have.
