Interactive Physics Atlas / Foundations + Mechanics I–II

Physics
Atlas.

Turn undergraduate classical mechanics into linked motion, graphs, forces, energy maps, collisions, rigid bodies, oscillations, waves, and orbits.

Analytic solutions where possible; fixed-step RK4, Verlet, and mode decomposition where necessary. Every active instrument shares a bounded animation lifecycle.

Physics Playground needs JavaScript for the live instruments.

The original projectile, double-pendulum, and wave instruments remain available. Classical Mechanics Atlas I adds linked kinematics, force diagrams, energy, momentum, and collisions; Atlas II adds rigid-body rotation, oscillations, waves, and central-force orbits. Core relations include ΣF=ma, τ=dL/dt, W=ΔK, and Ueff=U+L²/(2r²).
