F*d=1/2*mv

^{2}

So, naturally I started playing around with it

m*d*v/t = 1/2*m*d/t*d/t

m*d

^{2}/t

^{2}= 1/2 * m*d

^{2}/t

^{2}

1 = 1/2

What did I do wrong here? Did I divide by zero somewhere or something?

(I know that these equations are not relativistically correct but this seems ridiculous)
