Is this equation wrong? This is a equation for "uniform acceleration directed line motion at zero initial speed" in our textbook. S=1/2 at^2 Here is the list to compare the answer: t: 1 2 3 v: 2 4 6 If we use the equation to calculate, the answer is different to the list. For example, 1/2(2)(3*3) = 9, s=9 but in the list, it shows the answer is 12! Is my wrong? Or the equation is really wrong?
