Mass, roughly, measures an object's inertia, its resistance to being moved or stopped, once it's in motion.
Mass And Weight On Different Planets Worksheet. Pupils start by working out their mass on earth by using scales (this needs to be in kg). Weight is an entirely different thing.

But your weight is different because the moon's gravity is different. You have not changed of course, so your mass is always the same. This is why astronauts are take a look at your weight on other planets to learn more about how gravity works and be amazed at how much, or how little, you weigh on other worlds.
Weight is the force gravity exerts on an object due to its mass.
However, on the moon, in space, and on other planets, the pull of gravity is different. The values of the acceleration of gravity, g, are given for earth, the moon, mars, and jupiter. Weight is an entirely different thing. That's because the planets weigh different amounts, and therefore the force of gravity is different from planet to planet.
