Force

In this scene, the Force object first acts by means of repulsive forces and then by means of attractive forces (positive or negative Strength value).

The Force object ensures that each Rigid Body exerts its own radial gravitational force on every other Rigid Body within its range (can be activated via Objects per Dynamics Body tag). This can be a force of attraction, but also a force of repulsion.

If you switch off Gravity in the Preferences settings so that only the Force object is effective, the Rigid Bodies will have planet-like orbits (or clumps) if you shoot them at each other at a starting speed. To do this, set all attenuation values to 0.
