Question

My mass is what the stuff im having in my body. if i get into space station i become free from gravity. now there if i wish to measure my mass or weight, what is the method of doing it.

Answer 1

there are several ways of doing it. I think the simplest would be to throw an object forward, then measure its speed and yours. Via conservation of momentum, if your speed is v1 and its is v2, then your mass is v1/v2 times the mass of the object thown.
