🌐 Space Field Forces ▾

Each field permeates all space — any body present is automatically affected.

① Spring Field

Pulls every body toward the field centre. Stronger when further away.

k = 0.050

Centre (drag to set):

② Radial Field

Pushes (+) or pulls (−) bodies from a point. Like a space repulsor/attractor.

F = 20.0

− = attract · + = repel

③ Vortex Field

Swirls bodies in a spiral around the chosen axis. Great for angular momentum demos.

ω = 0.80

Axis:

④ Wind Field

Uniform push on all space — a constant background force in any direction.

F = 15.0
