The questions in this quiz are suitable for GCSE physics students studying momentum calculations, conservation of momentum and force and momentum. If you struggled with the quiz, don't panic - we've ...

When a magnetic material is bombarded with short pulses of laser light, it loses its magnetism within femtoseconds (10 –15 seconds). The spin, or angular momentum, of the electrons in the material ...

Photons can have half-integer values of angular momentum when they are confined to fewer than three dimensions. That is the conclusion of physicists in Ireland, who have revived an experiment first ...
