gravitysim is a dos app for particle gravity simulation with velocity
colored traces. Particles are randomly created (random initial mass, position
and velocity) for the simulation, based on supplied statistics. Simulation is
performed by calculation acceleration of all particicles in a given situation
using Newton's law of universal gravitation. The new position and velocity of
particles is calculated based on this acceleration for a small time value. This
process is repeated again and again.
Simulation of gravity is interesting in that even simple simulations like these
show how the solar system, and its planets might have formed. The movement trace
of the particles is indeed both wierd and elegant. The number of particles used
in the simulation can be changed, but as expected it will slow down the
simulation. Also the particles which move too close to each other afre assumed
to collide 100% inelastically. The net momentum of the particles is conserved.
Gravity Simulation configuration menu.
Particle count is the initial number of particles.
Gravity factor is the strength factor of gravity.
Time delta is the time difference between each simulation iteration.
Matter density is used to determine the size of particles for given mass.
Max. velocity is the maximum possible velocity of particles.
Max. range is the maximum possible position difference between particles.
Max. mass is the maximum possible mass of particles.
