Question

What is the weight in newtons of a 50 kg body on the moon and on the earth?

Answer 1

Explanation:

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.
