What Net impulse means in Physics A-Level, as defined for AQA.
Definition of Net impulse
Check what you remember
Read the wording for your board, then hide it and explain Net impulse in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
The total impulse over a complete interaction, found by treating areas below the time axis as negative so they reduce it.
