Newtonian kinematics, Euler integration, and radial inverse-square gravity wells.

ACADEMIC & ALGORITHMIC REFERENCE

// HISTORICAL ORIGINS

Formulated in Isaac Newton's 'Philosophiae Naturalis Principia Mathematica' (1687), classical particle mechanics models discrete point masses subjected to net external force vectors.

// GOVERNING EQUATIONS

F = m · a = G · (m₁ · m₂) / r² - γ · v

// BROWSER IMPLEMENTATION

Simulates 3,000 discrete mass points with explicit Euler integration. Velocity updates every frame via net gravitational, vortex, and damping drag forces.

// GUIDED EXPERIMENTS TO TRY IN THIS SANDBOX

1Orbit Vortex Balance

🎯 Action:Select 'Vortex Force' mode and click near the center while particles are moving.

✨ Observe:Particles collapse into an accretion spiral reminiscent of galactic whirlpools.

2Zero-G Elastic Collision

🎯 Action:Set Gravity to 0 and switch mode to 'Repulsor Wave'.

✨ Observe:Observe energy conservation and isotropic shockwave dissipation.
