About PhysicsFella

PhysicsFella is a free virtual physics lab for kids, students and teachers. Every experiment runs in your browser, so you can explore forces, gravity, magnets, circuits, light, sound and energy without any special equipment.

Who it is for

Our labs are designed for learners aged about 9 to 16. Younger explorers can play and predict what will happen, and older students can switch on the equations, take measurements and plot graphs.

How we build our labs

Each simulation focuses on one idea at a time and lets you change one thing and see the result straight away. The equations shown next to each lab match what students meet in school physics around the world.
