Every physics equation and what they mean
WebOct 25, 2009 · Mike. They simply describe motion of point masses for the special case of constant acceleration (and no air resistance, etc). Using the definition of velocity v = (change in position)/ (time interval) and acceleration a = (change of velocity)/ (time interval), one can derive 3 of the 4 kinematic equations: vf = vi + a*t.
