Alright, let's talk about this! So, when we say someone weighs less at high tide, we're not talking about how much they actually weigh on a scale. What we're talking about is how strong the pull of gravity is on them, and how that can affect their weight in a way that we can't actually feel or notice.
So, the first thing to understand is that the tides are caused by the pull of gravity from the moon and the sun. You can think of the moon and the sun as giant magnets that pull on the water in the oceans, making it bulge out in different places at different times. This is what causes the high and low tides that we see.
Now, when the water bulges out during high tide, it's actually pulling the surface of the Earth towards it. This means that if you're standing on the land near that bulging water, you're also being pulled towards it, just a tiny bit. And because you're being pulled towards the water, you might feel a little lighter than usual, even though you're not actually any lighter on a scale.
Think of it like this: Imagine you're standing on a playground roundabout, and someone starts pulling the roundabout around in a circle. You'd feel like you're being pulled towards the middle, right? That's kind of like what happens during high tide, except instead of a roundabout, it's the water that's doing the pulling.
But remember, this doesn't mean that you'd actually weigh any less on a scale. It's just how gravity is affecting you because of the tides. So, while it's a super interesting concept, it doesn't change how much you actually weigh!
