The only condition is: Acceleration must be constant You would have to use calculus if acceleration is changing

Delta

$△ A = A_{f ina l} - A_{ini t ia l}$

$v_{a vg} = \frac{v _{1} + v _{2}}{2}$ $v_{a vg} = \frac{△ d}{△ t}$ $△ d = (\frac{v _{1} + v _{2}}{2}) (△ t)$

$a = \frac{△ v}{△ t}$ $v_{2} = v_{1} + a (△ t)$

$△ d = (v) (t) + \frac{1}{2} (a) (t^{2})$ derived from subbing in equation 2 into equation 1.

$△ d = v_{2} (△ t) - \frac{1}{2} (a) (t^{2})$

$v_{2}^{2} = v_{1}^{2} + 2 a (△ d)$
