    I am not able to understand the formula s=(v+u)/2t. I know the graphical proof but not able to grasp it intuitively or based on just reasoning.

    So the equation is: s = t*(v+u)/2

    v is the finishing speed, u is the starting speed.

    Then (v+u)/2 looks like an average speed. This is also the speed halfway through the period. (true for constant acceleration)

    So distance travelled = (average speed)*(time). Look familiar?

    It is basically a generalisation of distance = speed*time.
