Relativity Lab Simulation environment in which you can discover Einstein's relativistic world yourself   |  © freudenthal instituut  |  Home  |

Perform virtual experiments by placing objects on the grid and giving them a velocity. Simulations can be observed from different reference frames. By comparing simulations in different reference frames, relativistic phenomena - such as time dilation and the relativity of simultaneity - become visible. Relativity Lab was developed by Paul Alstein, Kim Krijtenburg-Lewerissa, Wouter van Joolingen en Renee van den Heuvel. Relativity Lab is programmed by Robbe Ramon and Xavier Coppens. The worksheets were developed in collaboration with teachers Sander Hak, Lonneke Heijnen and Robert Wielinga.

Worksheets

We developed three worksheets to use Relativity Lab in the classroom. The first focuses on relative motion (non-relativistic), the second focusses on the light postulate and the relativity of simultaneity, and the third focuses on time dilation.
