I have problem undestanding newton's III law. When i press the wall the wall react with the same force on me but as I have less mass I have greater acceleration so I am moving away from wall. When I hit the wall according to newton's III law the wall should react with the same force on me (and give me acceleration) but I am not moving(away from wall). Can someone explain it to me? Also in the first example shouldn't I give a wall a little acceleration(even if a tiny bit) as well so why is the wall not moving at all?
