[SEL] OT: Physics Help & error correction

[John Neth]

Constant velocity has no acceleration.  Acceleration is a change in velocity or direction.  The instant a bullet fired vertically changes direction from up to down it has 0 m/s/s acceleration and that is different than 0 acceleration.  Points out the conceptual aspect of physics.
