Not platformers I realize, but lots of outer space games with actual acceleration/velocity calculations preceded SMB. Off the top of my head: Lunar Lander (1979), Asteroids (1979), Defender (1981), Gravitar (1982), Sinistar (1982). Just want to keep the history straight. Several of these modeled gravity as well.

Used to have a Gravitar clone for DOS. It was one of the harder games I've ever played :)
