What One-dimensional vector resolution means in Physics A-Level, as defined for AQA.
Definition of One-dimensional vector resolution
Check what you remember
Read the wording for your board, then hide it and explain One-dimensional vector resolution in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
All velocities lie along a single straight line, so momentum conservation becomes a scalar equation once a positive direction is chosen.
