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?

Answer 1

When you get in the pool you displace some water. This causes the water level to rise slightly. Each square centimetre on the bottom of the pool now has a taller column of water above it. That taller column is heavier, and so applies a greater force on the bottom of the pool. So you getting in increases the pressure exerted on the bottom, and so the entire pool carries your weight.

If the pool was already full then some water would slosh over the sides, and that amount of water would weigh the same as you, so the total weight of water + person in the pool would stay the same.
