How do you work out acceleration in Physics?

http://en.wikipedia.org/wiki/Acceleration.
a= change in velocity/change in time
a=Δv/Δt
.
a good way of remembering is that velocity is in "metres per second" and acceleration in "metres per second per second" so "velocity per time" hence a=v/t
.
e.g. "find the average acceleration of a frame that accelerates from 0m/s to 10m/s over 5 seconds"
.
the velocity changed 10 units over 5 units of time, 10m/s over 5sec
Δv=10 and Δt=5
by the formula above: a=10/5
a=2
the frame accelerated 2metres per second every second over 5 secs
a=2m/s/s or m/s²
