this by the way isn't accurate because acceleration isn't uniform.
Another way to look at it:
Acceleration = F/m, where F is the net force applied to a mass, m.
a=f/m,
acceleration in terms of velocity.
a = v - u/t Delta Velocity divided by Time.

A = ΔV ÷ T Acceleration is worked out by (final speed - initial speed)/ time taken for change in speed a = v2-v1/ t2-t1 Strictly you should say velocity ie the speed in a certain direction. Youalso have the formula f=ma which tells you that the force needed to get something moving will be the mass of the object multiplied by the accelertion you want to achieve; so from this formula if you know force and mass you can work out acceleration. The formula for acceleration is: Vf-(Vi)/t ie. change in velocity per unit time. Instantaneous acceleration in its differential form is d2x/dt2 where x is a function of time t.
Acceleration is the time rate of change of velocity.

That is, acceleration =dv/dt (v - velocity ; t - time)
Or simply acceleration = change in velocity / time
