Question

If I have weight 50kg on earth(in weighing machine)will my weight be the same in space?

Answer 1

Answer:

First you must realize that kilogram is the standard unit of mass and mass of a body does not change any where in the universe because mass of a body depends on the number of particles in a body and this count remains same if the body is taken any where in the universe however your weight will be different at moon because weight is the force of attraction towards the center of all the heavenly bodies. So if your weight here on the Earth =w=mg=50 kg x9.8N/kg =490N, then on the surface of moon your weight will be w= mg=50kgx1.63N/kg=81.66N, because gravity of moon is less than the gravity of earth.

Yes this is a complex answer,but in simpler words the answer is no,it wont be the same

Answer 2

No. Weight on earth is usually lesser than your real weight because whether you like it or not, you're considered a particle in the air, and you're prone to the air's buoyancy( to explain this, you need to understand Archimedes Principle). This buoyancy affects your weight just as it produces apparent weight loss of objects in water.
Hope you understood.
