Paper 1, Paper 2 5 marks Difficulty 4

Relativistic total energy in mc squared units

A particle in a train-frame measurement study has rest mass \(1.8\) in arbitrary mass units and moves at \(0.52c\). Calculate its total energy in units of \(c^{2}\). Enter the numerical result and choose the interpretation that matches the physics meaning.

Worked practice: physics data and result

Read the physical quantities first, then calculate the result and state what it means.
