Interactive Physics Simulations
Run experiments you can't do in a classroom. Every simulation is free, runs in your browser, and lets you change the variables to see how the physics responds.
Kinematics
Classical Mechanics
Collision Lab
Simulate elastic and inelastic collisions between objects. Visualise conservation of momentum and energy in real time.
Play simulation →Energy Conservation Ramp
Roll a ball down an adjustable curved ramp and watch kinetic, potential, and heat energy trade off in real time.
Play simulation →Stopping Distance & Crash Energy
Compare two vehicles braking from different speeds and see how stopping distance and kinetic energy scale with the square of speed.
Play simulation →Simple Pendulum
Watch a pendulum swing and measure its period. Change length, mass, and gravity to explore simple harmonic motion.
Play simulation →Inclined Plane
Slide a block down a ramp. Adjust angle, mass, and friction to see how forces resolve along and perpendicular to the surface.
Orbital Mechanics
Place satellites in orbit around a planet. Explore circular, elliptical, and escape trajectories under Newtonian gravity.
Electromagnetism
Circuit Builder
Build series and parallel circuits with resistors, batteries, and switches. See current, voltage, and power update live.
Waves & Optics
Wave Interference
Combine two waves and see constructive and destructive interference patterns form. Control frequency, amplitude, and phase.
Standing Waves on a String
Generate standing waves by adjusting tension and frequency. Watch nodes and antinodes appear at resonant frequencies.
