About Coulomb's Law
Visualize the electrostatic force that two charges exert on each other. Observe how changing the sign and magnitude of the charges and the distance between them affects the electrostatic force.
How to play Coulomb's Law

Questions & answers
- What is Coulomb's Law?
- Coulomb's Law is a free interactive simulation from PhET Interactive Simulations (University of Colorado Boulder) that you can play right in your browser on crumble.lol — no downloads and no sign-up. Visualize the electrostatic force that two charges exert on each other. Observe how changing the sign and magnitude of the charges and the distance between them affects the electrostatic force.
- What can kids learn from Coulomb's Law?
- It helps kids explore: relate the electrostatic force magnitude to the charges and the distance between them explain newton's third law for electrostatic forces use measurements to determine coulomb’s constant determine what makes a force attractive or repulsive.
- What age is Coulomb's Law good for?
- It is designed for high school up to university, and curious kids outside that range can absolutely enjoy poking around it too.
