In both my Maths and Physics exams they give these equations of motion:
v = u + at
v2 = u2 + 2as
s = ut + (1/2)at2
s = (u+v/2)t
However the following equation is never included (even though it can simplify some problems significantly)
s = vt - (1/2)at2
Why is this deliberately omitted by the exam boards? Is it because this formula can only be applied in certain situations ?
Thanks
