Classical Mechanics

Newtonian Gravity Engine

Simulate N-body gravitational attraction, orbital trajectories, solar system dynamics, and escape velocities using Newton's inverse-square equation:

$$F = G \frac{m_1 m_2}{r^2}$$

N-Body Simulation Orbital Traces Vector Controls

Active Lab Launch

Orbital Mechanics

Kepler's Laws Lab

Interactively demonstrate planetary motion laws: elliptical focal paths ($a, e$), equal area swept per time interval, and harmonic period scaling:

$$T^2 = \left(\frac{4\pi^2}{GM}\right)a^3$$

Elliptic Foci Area Sweeps T²/a³ Harmonic Ratio

Active Lab Launch

Relativistic Physics

General Relativity Engine

Visualize spacetime curvature around Schwarzschild black holes, relativistic perihelion precession (rosette orbits), event horizons, and gravitational lensing:

$$r_s = \frac{2GM}{c^2}$$
