A person does 15 J of work moving a couch 1.3 m. How much force was used?​

11.53 N.

Explanation:

Work = Force * Displacement

W= 15 J

D = 1.3

And now you solve for Force.

15= 1.3F

F= 11.53 N

I think that up and down is just gravity pulling us up and down, but because there is no gravity, I don’t think there is an up and down. You might think you ate facing up but you could be facing down.
U... maybe you’ll find another solar system or other stars?
Idk hope this helps if not have a good day
