Gravity Sling

Reference Manual & Technical Spec

Gravity Sling — Overview & Engineering Principles

Gravity Sling is an orbital mechanics simulation and gravity sandbox. It models Newtonian gravitational dynamics in real time, allowing users to place gravity wells and launch projectiles to observe orbital capture, slingshot vectors, and escape velocities.

Zero-Trust Client Execution

The physics integration engine is built entirely on HTML5 Canvas and runs on your local CPU. No trajectory logs or session data are tracked, enabling standard offline gameplay without tracking.

Step-by-Step Operation Guide

  1. Tap or click on the canvas to place high-mass gravity wells in the sector.
  2. Click and drag from your launcher node to define the initial launch vector.
  3. Release to launch the kinetic projectile and watch Newtonian gravitational forces interact.
  4. Reset the field or clear gravity wells to run alternative orbital experiments.
