what does suvat stand for
s= displacemnt, u=intitial velocity, v=final velocity, a=acceleration, t=time
gradient of a velocity time graph
acceleration
area of a velocity time graph
displacement
stopping distance=
braking + thinking distance
thinking distance=
reaction time x speed
braking distance
fd=1/2mv^2
displacement
how far an object has travelled from the starting point
what influences thinking distance
tiredness, illness, distractions, alcohol or drugs
factors influencing braking distance
