Why jumping into water from great height feels like landing in concrete?

For the same reason that when walking you barely feel the wind, when running you feel a little breeze, when biking you need to partially close your eyes and if you’re going in a car 100kph you cannot stick your body outside the window.
The faster you go the hardest the water pushes against your movement.

Next time you’re at the pool, slowly lower your hand into the water palm facing down, doesn’t hurt right? Now slap the water as hard as you can palm facing down. There’s a physics law that says as hard as you push on something, it pushes on you. And another that says force is acceleration multiplied by mass, or weight. Basically to push water out of the way, you do it slowly or fast. The weight of the water doesn’t change, so you get a relationship where if you push water faster, you have to push it harder. Think about throwing a heavy ball faster. But, that first law comes back in, and all the force, or pushing power you have to give to the water, gets pushed back at you. That’s why punching a brick wall hurts you and the wall, but the wall can take it
