In our daily life when we ask the difference between mass and weight from people then the answer of the people is that the mass and weight are the same but actually these are not the same according to physics.
The amount of matter contained by anybody is called it’s Mass. Mass remains the same at any location in the Universe. Mass of anybody remains the same on the earth and on the moon or anywhere in the universe.
Weight depending on the gravitational field. Weight is the force exerted by the body in the gravitational field.
Gravitational Field of moon and earth is not the same due to which it affects the weight. So we can say that the weight of the same object on the earth and the moon will different because of the difference in the gravitational field.
