How do I simulate a see-saw balance?

Open this page and use the live Electrostatics tool below — set your inputs and the simulation runs instantly in your browser using real numerics. No install, no account needed.

Yes. The simulation runs free in your browser. A one-time unlock or a Pro plan adds advanced parameters, saved presets, data import, and clean exports.

Can I use my own numbers?

Absolutely — every input is adjustable, and with data import you can drive a see-saw balance from your own measurements.

Governing equation

V (r) = k i \sum \frac{q _{i}}{r _{i}}, k = 5000, \sum q_{i} = 0

Reading this result: The potential at any point is the superposition of every charge's k·q/r term, so overlapping fields simply add. Field lines run from high potential to low — out of + charges and into − charges — always crossing the equipotentials at right angles.

About this simulation

The full Electrostatics tool models a see-saw balance with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
