Detectable Gravitational Waves can be created by massive compact objects (like black holes or neutron stars) that orbit each other. How can we model this with everyday materials? How can we use Tracker to carry out digital video analysis of our model to study the circular motion?

There is a strong emphasis on science investigation skills, interpreting data and making interdisciplinary connections.

Thank you for the contributions to this activity from Polar Star teacher advisors Christian Collette, Maria Eleftheriou and Paula Galvin. 

The activity was created within the POLAR STAR project, co-funded by the Erasmus+ Programme of the European Union (2019-1-FI01-KA201-060780).
