Can You Hit Your Table Tennis Bat on the Table?

Question: Can You Hit Your Table Tennis Bat on the Table?

Can you knock your bat against the table top during play? E.g. you smash the ball perfectly but as your bat comes down it hits the table. I understand that if it MOVES the table, that is a fault. BUT any touching a table WILL move it (by Newton's equal and opposite law of motion), it just may not be obvious / apparent to the eye. SO, does it matter if a player does this?

Advice please!!

Thank you,
Janet

Answer:

Hi Janet,

Yes, you can knock your bat against the table top during play, provided you don't move the table. In fact, you can lean, sit or even jump up onto the table during a point, provided that you don't move the playing surface! Umpires will only rule that the table has been moved if they can see it move with the naked eye - if they can't see it move, then as far as they are concerned, the table hasn't been moved. This is the only practical way to deal with that situation.

The only thing that can't touch the playing surface is your free hand, regardless of whether you move the table or not.
