Vehicle safety engineering
What Vehicle safety engineering means in Physics A-Level, as defined for AQA.
Definition of Vehicle safety engineering
Check what you remember
Read the wording for your board, then hide it and explain Vehicle safety engineering in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
Crumple zones, seat belts and airbags increase the time taken for the vehicle and occupants to change momentum, reducing the average force for the same momentum change.
