Anon....THIS is what we have....many of us...been trying ot explain, to the OP.
I'll expand on your 'spacesuit' example, to hopefully make it better.
IF you, in our 'spacesuit'...let's call it an EVA suit, since it's more appropriate.....NOW, if you in the EVA suit....you managed to bring a
heavy rock, or any other weight out with you....NOW, there you are!
OK....YOU, and everything that is on or part of you, has MASS. Every Mass has a C/G...a Center of Gravity.
You take that 'rock', and 'throw' it.....well, it has MASS....and the act of 'thowing' it means it imparts a momentum on you, as you toss it
Your C/G is close to our middle....but your arm is extended, as you toss the rock.....so that is known as a 'moment' in physics.
Back to Newton....the 'throwing' of the rock results in an equal and opposite reaction.....
NOW....here's the part to understand....the rock, thrown from the Astronaut's hand, was not near his C/G....so, this will result in a spinning
motion, of the Astronaut.
NOW....if this Astronaut wishes to throw rocks, he/she does so at their risk.....because of what I just described.
IF you are standing on the surface of an alien planet.....in your EVA suit....then that emans there is a gravity, of some sort....
If you are floating in space, in your EVA suit....then it is different!!!
IF you can't figure out the difference, then go back to school!!!
