How can an astronaut weigh different amounts when in different locations

So, there’s this thing called the force of gravity and on Earth, it is what keeps you on the ground. On Earth, gravity gives physical objects weight. But the moon’s gravity is much weaker. This means that you would weigh less on the moon because there’s less gravity and it’s harder to stay down. This is why astronauts can look like they are hopping and skipping on the moon’s surface. Compared to Earth, they feel weightless.
