2D Gravity Simulation
Interactive Newtonian sandbox that lets you spawn bodies, pan the origin, and watch how gravity shapes their orbits. Field vectors, velocity indicators, and long-range predictions make the dynamics easy to read at a glance.
Description
- Implements Newton's law of gravitation across movable bodies while handling reaction forces on anchored masses.
- Predicts the next 1000 simulation ticks and renders blue trajectory trails so you can spot stable orbits versus escapes.
- Draws a low-detail gravitational vector field to reveal how nearby accelerations bend space around heavy bodies.
Controls
Click to insert a new gravity object.
Drag to pan the origin and explore the field.
R randomizes current object positions and velocities.
