As it is now, you get maybe one second to react to a fast ball coming at you. If the court was 6X bigger, you would have what would look like 6 seconds or so before the ball gets to you, enough time to go off court, get a squirt of water, come back and then hit it back
OK, here it goes. Taking into consideration only the gravity and not any difference in density/friction of air on moon surface, I think that, ...

Yeah, that could fly

Still, if the court was 400 + feet long, you would do a LOT of running to chase down balls. I guess the lower gravity would reduce the amount of energy used to cover such distances but it would still be a lot of running!
Another problem is how the players run around. They probably couldn't run normally because there woudn't be enough traction and might have to do bounding leaps like astronauts on the moon.

I somewhat disagree about the slow bounce, the apollo astronauts bounced around on the moon, seemed to go pretty fast. Maybe it would be some kind of wheelchair sport with the chair tied to a giant etch-a-sketch kind of mechanism which whips you around the court to get the balls. I still like the magnetic field concept to simulate gravity at least as far as the ball is concerned, that would allow a standard sized court.
You wouldn't be able to trot off the court get a drink and still have time to return the ball. In 1/6 gravity a step would translate into a bound, a very slow bound. In order to accelerate to a sprint you need at least four or five steps to come up to speed. How much speed can you generate with only one step? Movements while exaggerated would appear to t ...[text shortened]... eing able to spot the ball though. Maybe if it were a luminescent ball you could easily see it.
Originally posted by wolfgang59Of course it's related to mass. If it were freefalling in a gravity field, all masses would react pretty much the same, but we are talking about a tennis ball getting whacked by a racket which is a kinetic acceleration, just like a bullet in a gun, if the same powder charge in two bullets goes off, one bullet is lighter than the other, the smaller mass will accelerate faster, the heavy one will be slower, have less acceleration. Same with the tennis ball. The acceleration comes in the extremely brief time it is in contact with the racket where the strings are stretched back a bit and then snaps the ball forward. If the ball is heavier, it will not be going as fast when it leaves the racket. You have to picture that effect in extreme slowmo. When the ball makes contact with the ground, there is a further deceleration and reacceleration that changes the trajectory of the ball, the energy of that change came from the racket and the human swinging it.
The players will be hitting the ball with the same force as on Earth so mass IS relevant.
