Hello Stuart: We have had this "conversation" before.
Your second question(when does an asteroid become a meteoroid): There is no real minimum asteroid size or maximum meteoroid size. When it comes up as a question, I usually say 5 or 10 meters is the crossover. Also, if an asteroid gets hit by something else, it will make lots of meteoroids! Your second question (when does a meteoroid become an asteroid): any small object that is not a comet (or man-made) when it has been observed and an orbit around the Sun is determined (even poorly) is an asteroid. The Minor Planet Center gives designations to asteroids (minor planets), not meteoroids. So, this could mean that an object only a few meters in diameter can be given asteroid status.
