When we talk about mass and weight, it's really important to know the difference!
Mass is about how much stuff is inside an object. This is measured in kilograms (kg). No matter where you are in the universe, an object's mass stays the same.
For example, if you have a ball that has a mass of 1 kg, it will always be 1 kg, whether you’re on Earth or floating in space.
Now, let's look at weight. Weight is the pull that gravity has on that mass. We measure weight in Newtons (N).
The weight of an object can change depending on where you are. For instance, that same 1 kg ball weighs about 9.8 N on Earth because of gravity. But if you were on the Moon, it would weigh less—around 1.6 N—because the Moon has less gravity.
To wrap it up:
So, the next time you weigh something, remember you’re measuring how gravity pulls on it, not just how much stuff is in it!
