v is final velocity.

What is the formula that links acceleration, velocity, and time?


(there are 3 forms of this formula)

These 3 formulas mean the same thing, but use different words & symbols:


  1. a = change in velocity / t
  2. a = Δv / t
  3. a = v - u / t


(v = final velocity, u = initial velocity, t = time)
