Talk:Equation of motion

Can anyone remember how those 4 equations are derived (presumably, from Newton's Laws)? -- Tarquin

Notation
Is anyone else bothered by the fact that at least 3 different notations are used in this article, e.g. d = distance = s; initial velocity = u = v0 = vi; etc. etc.
- Also, why 'current'? These equations work perfectly well if the 'final velocity' is not current. Ian Cairns 16:48, 13 Oct 2004 (UTC)
- To go from (equation 2) average v = s/t to (motion equation 2) s = 1/2 * (u + v) * t, you need to remember that under a constant acceleration, the average velocity is half the final velocity. -- Anonymous Coward
- If we're being picky, d represents distance (a scalar) while s represents displacement (a vector). It does bother me, but they're all easily derived using mental logic. ThomasWinwood 19:07, May 11, 2005 (UTC)

Missing equation
What happened to s = vt - ½at²? ThomasWinwood 19:08, May 11, 2005 (UTC)
