If I’m in a pool, does my weight push down on the bottom if I’m floating?

Question

Is the bottom of the pool supporting the same amount of weight whether or not I’m standing on the bottom or floating on the surface?

Edit: thanks! Something something Archimedes

Answer 1

In order for you to be motionless in the pool, the total force on your body must be zero (thanks, Newton). When you’re in the pool, gravity doesn’t disappear. It’s still pulling you down. Which means something must be pushing back up.

You could (rightly) claim that the water is pushing you back up. But then there would be more force pushing down on the water. The water isn’t accelerating down, so something must be pushing it back up (it’s the bottom of the pool).
