Are table tennis and tennis the same?

Answer 1

similar, but not the same, no.

for example, when serving in Table Tennis, the ball must hit YOUR side of the table, bounce over the net and then hit your opponents side. in regular tennis, it just needs to hit your opponent's side.

the rules that are the same include:

the ball must not bounce more than once on your side of the net, or you lose that point

you may not hit the ball more than once when it is on you side of the net (meaning, if you hit it into the air straight up, you may not then hit it again to try to get it over the net)

serving is done behind the back line, and must be done from one quadrant of the court (or table) and needs to bounce on the quadrant kitty-corner from the serving quadrant.
