Physics you can see, change, and test
Five browser-based experiments that turn equations into motion, measurements, and intuition. Adjust real parameters, make a prediction, and watch each model respond.

This is a source-available collaboration project. You may use the official simulations and fork the repository to prepare a pull request. Selling, redistributing, rehosting, or reusing the projects elsewhere is not permitted. Read the license summary before making a local copy.
Each lab pairs an interactive model with live measurements, graphs, and controls. Start with a familiar equation, then push it until your intuition catches up.
|
EXPERIMENT 01
See how light transfers energy to electrons and produces a measurable photocurrent. Adjust |
|
EXPERIMENT 02
Measure oscillation in real time and compare it with the small-angle model. Adjust |
|
EXPERIMENT 03
Follow displacement, velocity, acceleration, and energy through a complete oscillation. Adjust |
|
EXPERIMENT 04
Explore the relationship between temperature, emitted spectrum, and the visible-light region. Adjust |
|
EXPERIMENT 05 · NEW
Build intuition for voltage, resistance, current, and electrical power in a complete series circuit. Adjust |
| Experiment | Core ideas | Live lab |
|---|---|---|
| Photoelectric Effect | Photon energy, work function, stopping potential, photocurrent | Open |
| Simple Pendulum | Period, gravity, length, angular motion, energy | Open |
| Simple Harmonic Motion | Amplitude, angular frequency, phase, spring force, energy conservation | Open |
| Blackbody Spectrum | Temperature, spectrum, Wien's law, visible light | Open |
| Ohm's Law Circuit | Voltage, resistance, current, power, series circuits | Open |
| Adjustable controls | Live response | Graphs and measurements |
|---|---|---|
| Change the model | Watch the response | Compare the physics |
| Work with meaningful physical parameters instead of fixed animations. | See motion, charge flow, energy, and measurements update together. | Connect each live result to equations, traces, and idealized models. |
Every simulator uses plain HTML, CSS, and JavaScript. There is no framework to learn and no build pipeline between an idea and the browser.
- A Dinglo-native dark instrument interface aligned with the other physics labs
- A scientifically structured circuit with a DC source, switch, resistor, series ammeter, and parallel voltmeter
- Independent voltage and current controls with live resistance calculated from
R = V ÷ I - Animated charge flow whose speed responds to current
- Live
V,R,I, andPmeasurements plus conductance, power, and one-second energy - A fixed-scale voltage–current graph with the calculated-resistance response and current operating point
- Four experiment presets and an eight-row observation notebook with CSV export
- Responsive controls, keyboard focus states, semantic labels, and reduced-motion support
This repository is designed for focused, useful pull requests. A contribution can be as small as one corrected label or as ambitious as a complete experiment.
| Focus | Valuable contributions |
|---|---|
| Interface | Improve mobile layout, keyboard access, screen-reader labels, or control clarity. |
| Physics | Correct an equation, unit, explanation, graph label, or numerical method. |
| Learning | Add presets, guided challenges, classroom questions, or clearer feedback. |
| Performance | Improve animation smoothness, rendering efficiency, or numerical stability. |
| Reach | Translate simulator text or propose a new browser-based experiment. |
If something feels confusing, open an issue. If you can improve it, fork the repository and send a focused pull request.

The small, predictable structure lets contributors work on markup, styling, or simulation logic without searching through a large framework.
- Check the existing issues or open one that describes the change.
- Create a focused branch in your GitHub fork.
- Make and test the change locally.
- Keep simulator HTML, CSS, and JavaScript in separate files.
- Submit a pull request explaining what changed, why it helps, and how you tested it.
