    I know that the formula is as follows:
    s=ut + 1/2(at^2)
    But my question is why is this derivation incorrect , where's the fault?
    V = u+at
    S/t = u + at
    S = ut + at^2
    I know the half is missing but I'm not sure it seems to work algebraically
    Thanks in advance

    v is the final velocity
    s/t =v gives the displacement if you're travelling at constant final velocity

    s=ut+1/2at2 gives you distance covered while under a constant acceleration - not at constant velocity.

    you've mixed up formula for constant velocity and constant acceleration.
