From the formula of uniform linear motion v = s / T, it can be seen that the velocity is equal to the ratio of displacement to time, which has nothing to do with velocity and displacement. Why is it wrong

For example, if r = u / I, the resistance made in other people's field is no matter how much voltage you add. It's just a way to calculate the resistance,
