Settling to balance

Hang a mass on a spring and physics solves an equation for you: the mass sinks, oscillates, and settles exactly where the spring's pull equals the weight, k·x = m·g. Scrub the mass and the stiffness and watch it re-settle to the new answer, live.

m·ẍ = m·g − k·x − c·ẋ, integrated live; Node-verified to settle at x = m·g/k (±2%). Heavier sags more, stiffer sags less, equilibrium is where the force arrows match. Built on the reusable probe.js primitive. Runs on your device. · Institute for Physical AI @ JBI
