F = ma is Newton's 2nd Law of Motion, which can be used to determine acceleration if F and m are known.
I'm not entirely sure what you are trying to do. My guess is that you've got v-u/t from the equation of motion v = u + at, where v is the current velocity, u is the initial velocity, a is the acceleration, and t is the time duration that the body has been accelerating for.
To calculate acceleration, use the formula that matches the information you have.
If you know the force and the mass:
a = F/m
If you know the initial velocity (u), current velocity (v) and the duration of the acceleration (t):
a = (v - u) / t

Force= mass x acceleration

a = Force/Mass
a = metres/second squared
F = Newtons
m = Kg
(newton's second law)
And yes, a does equal (v-u)/t, but that formula is derived from motion in a straight line, and hence can only be used for objects travelling in a straight line.

a= F/m is correct.
a= dv/dt ore change of speed pr second.
v is the speed.
I do not know the unit u which you have used.
