Estimating Braking Force (AQA GCSE Physics): Flashcards

Kinetic energy → thermal energy

Slows wheels by pressing brake pads against them

KE converted to thermal energy

Kinetic energy

Greater deceleration

Vehicle could lose control

Brakes could overheat

$v^2 = u^2 + 2as$

$a = \frac{v^2 - u^2}{2s}$

$F = ma$
