Rate of change of velocity over time
metres per second squared (m/s2m/s^2m/s2)
When it speeds up or slows down
a=Δvta = \frac{\Delta v}{t}a=tΔv
Change
Δv=v−u\Delta v = v - uΔv=v−u
Initial velocity
Vector
Size and direction
Object is slowing down (deceleration)
Velocity changes by the same amount in equal time intervals
v2=u2+2asv^2 = u^2 + 2asv2=u2+2as
