Physics Calculators, Simulators & Visualizers
Free interactive physics calculators and simulations for mechanics, motion, waves, sound, thermodynamics, fields, oscillations, and introductory physical models.
Explore Physics
Explore physics with interactive calculators and simulations that connect equations to motion, graphs, and physical behavior. Tools cover mechanics, oscillations, waves, sound, thermodynamics, and other foundational models.
The workbenches emphasize unit-aware inputs, visual interpretation, documented assumptions, and bounded simulation values suitable for learning and problem checking.
Common topics
- mechanics calculators
- projectile motion
- waves and sound
- thermodynamics
- oscillations
- chaos
- energy and momentum
- physics simulations
Analyze experimental data and uncertainty
Import CSV measurements, inspect distributions and regression residuals, build Type A/B uncertainty budgets, and compare analytical sensitivities with seeded Monte Carlo. Original data and exclusion decisions remain visible.
Explore traveling waves and high-frequency design
Use Smith charts, design matching networks, inspect Touchstone S-parameters, trace receiver noise, and investigate microstrip geometry and waveguide cutoff.
Physics tools
Open a calculator, simulator, visualizer, or reference workbench.
Chaotic Pendulum Forecast Lab
Integrate a two to seven arm pendulum with Runge-Kutta and race three statistical forecasters against deterministic chaos.
