What ion vibration and collisions means in Physics GCSE, as defined for AQA.
Definition of ion vibration and collisions
Check what you remember
Read the wording for your board, then hide it and explain ion vibration and collisions in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The metal ions in the lattice vibrate more strongly at higher temperature, so the electrons carrying the current collide with them more often and find it harder to pass.
