Even though there is no one there, it is because you haven't posted. I'm sure more people will go if they see an unanswered topic. I don't know much about that so I don't want to give you a wrong answer.

As I think:

1: If you dont touch or dont give acceleration to something in space, he will continue to move at his initial speed and in the same direction.

2: it will not be the same because : Acceleration = Force/Mass... Then if the mass is higher, you'll get a lower acceleration

3: Can't answer this sorry
