I'm Etalie, I'm currently studying for my AS levels and will (hopefully) be posting revision entries on psychology and sociology.
I previously uploaded posts on GCSE revision. If it helps you then great! But I'm not an expert on anything AT ALL so don't rely on everything I post.
(Also, I'm not taking credit for any of the pictures or info here, it's all off google images, notes from BBC bitesize and CGP revision guides, textbooks etc)

(NB - GCSE: italics in the science subjects are things that are only in paper 2!)

1 - FORCES AND MOTION 

Stopping distances - 

Stopping distance - time between first spotting a hazard and the car coming to a complete stop 

Thinking distance - time between driving noticing hazard and applying brakes 
Affected by: 
  • How fast you're going 
  • How aware the driver is - eg: tiredness, drugs, alcohol, age, inexperience 
Braking distance - distance the car travels during deceleration while brakes are being applied 
Affected by: 
  • How fast you're going 
  • Mass of vehicle (the larger the mass, the longer it takes to stop)
  • Quality of brakes 
  • Grip - road surface, weather conditions, tyres
