I keep seeing people talking about how swimming records aren’t being broken on these Olympics because of the pools being too deep.
In: Physics
Imagine a powered windmill in a pool. As it spins, it pushes the water down and away. If you were under water, you would feel these waves of water going past you.
Now if the pool is too shallow, those waves will hit the bottom of the pool and bounce back up, up to the windmill! This would slow it down because it would push back.
That’s kind of what’s happening at the Olympics. The pool is more shallow than usual, so the waves the swimmers are making are bouncing back and making it harder to swim.
