Visual Physics Lab

Interactive physics simulations to build intuition. Drag, adjust, and explore fundamental physics concepts.

Mechanics

Projectile Motion

Launch projectiles at any angle. See trajectory, velocity components, range, and max height with stroboscope markers.
Mechanics

Pendulum & SHM

Explore simple harmonic motion with pendulums and springs. See displacement graphs, energy bars, and damping effects.
Mechanics

Collisions

Simulate elastic and inelastic collisions. See momentum vectors, energy bars, and center of mass tracking.
Mechanics

Inclined Plane

Explore forces on an inclined plane. See free body diagrams, friction, normal force, and sliding conditions.
Mechanics

Torque & Rotation

Apply forces to levers, spin disks, and observe rolling. See torque, moment of inertia, and angular momentum.
Mechanics

Orbital Mechanics

Explore Kepler's laws and elliptical orbits. Adjust eccentricity and see vis-viva speed, sweep areas, and escape velocity.
Optics

Lens & Mirror Ray Diagram

Draw ray diagrams for convex/concave lenses and mirrors. See real and virtual images with standard rays.
Optics

Snell's Law

Visualize refraction at material boundaries. See total internal reflection, critical angles, and Snell's law in action.
Optics

Diffraction Patterns

Visualize single slit, double slit, and grating diffraction. Adjust wavelength and slit width to see intensity patterns.
E&M

Electric Field Simulator

Place charges and see field lines emerge. Drag charges to explore dipoles, quadrupoles, and parallel plates.
E&M

Magnetic Field

Visualize magnetic fields from bar magnets, wires, loops, and solenoids. See field lines, compass needles, and iron filings.
E&M

Circuit Simulator

Build series, parallel, and combo circuits. See animated current flow, voltage drops, and Ohm's law in action.
E&M

EM Induction

Push a magnet through a coil or spin a generator. See Faraday's law, Lenz's law, and induced EMF in real time.
Waves

Wave Interference

See constructive and destructive interference patterns from two point sources. Pixel-level intensity rendering.
Waves

Standing Waves

Explore harmonics on strings and in pipes. See nodes, antinodes, and the relationship between wavelength and frequency.
Waves

Doppler Effect

Watch wavefronts compress and expand as sources move. See frequency shifts, Mach cones, and sonic booms.
Mechanics

Pulley Systems

Explore fixed, movable, and block-and-tackle pulleys with 2n mechanical advantage. Simulate Atwood machines.
Thermo

Ideal Gas Law

Explore PV diagrams for isothermal, adiabatic, isobaric, and isochoric processes. See work, heat, and internal energy.
Modern

Photoelectric Effect

Shine light on metals and observe electron emission. See how frequency, not intensity, determines if electrons escape.
