Understanding the Physics Behind the "Gravity" Movie Scene

Hi everyone,

I recently watched the movie "Gravity" and was fascinated by the realistic depiction of space. One scene that particularly caught my attention was when the characters use their thrusters to navigate through space. I'm curious about how accurately the movie portrayed the physics of such maneuvers.

I also check this: https://aplusphysics.com/community/index.php?/blogs/entry/29979-another-example-of-physics-in-a-moviealteryx But I have not found any solution. Could someone explain the real physics behind using thrusters in zero gravity? How close is the movie's depiction to what actually happens in space? Any insights or explanations would be greatly appreciated!

Thanks!
