Relativistic Momentum

This lesson allows students to establish the formula for relativistic momentum from experimental data.

DVD (15 minutes)
This lesson uses a very clear but not flashy video from TRIUMF called "Approaching the Speed of Light". It shows the cyclotron, beam line and bending magnets and uses animations explains clearly how particle speeds and momenta are measured and then provides data for the students to analyse. You can get a copy of this DVD and another exploring how electromagnetism is used at TRIUMF for free here.

Worksheet (30 minutes)
The DVD comes with a worksheet but I put together my own worksheet. Instructions for the teacher and answers can be found in the teacher's notes. The worksheet with answers has been translated into French by Nanouk Pare of Montreal. Merci Nanouk! mouvement relativiste.
