Moon Sports

Playing catch with on the moon would have its ups and its downs. The moon has less accelerating due to gravity so you and the ball would weigh less. You wouldn't need to excerpt yourself as much (use as much muscle power) to make the ball move. As you through the ball it would have more of a tendency to rise higher because there is not as much acceleration due to gravity. You could throw the ball farther because there isn't air pushing against it. There is less friction making it slow down so it goes faster for a longer distance. You would have to wait longer for the ball to come down to level where you can catch it but it would be easier to catch because it doesn't weigh as much.
It would be interesting to try to play on the moon and see just how different it is. I think it depends on the person whether playing catch on the moon will be easier or harder.
