How is it that the moon can affect the 352 quintillion gallons of water in the ocean, but not affect us?

Question

The moon depending on where it is at your time of day can affect whether or not there’s high or low tides. Basically moving all of the water in the ocean, at least that’s how I think. But how come it doesn’t make us feel lighter or heavier throughout the day? Or just seem to affect anything else

Answer 1

Because gravitational attraction is a function of BOTH masses.

F = gMm / r^2

So if you have tow really big masses, like the moon and the worlds oceans, there’s a lot of force there.

But if you have one big and one little mass, then you have significantly less force.
