i believe that can be easily explained by newton first law.- u& A7 y8 A: N
When no net force act on a object, the object will travel with constant velocity.
2 i- Z( [7 |& s) M, w+ k- y
- h8 w( L, F4 t1 F" {6 }1 C  X1 _) n
Since the water on the earth will be attracted by gravitational force, it will fell on the ground.
- N" W! ^) J  I  _0 g+ _9 Z' v5 i& _; k( X( a7 l1 h9 {9 B
But in the space, no force is added on the water will u X the ball ,so the water will remain its old velocity(don't move)
