Dynamic pressure

Okay kiddo, do you remember how when you jump into a swimming pool, you feel like the water is pushing you back? That's because of something called dynamic pressure.

When you move through a fluid (like air or water), the fluid wants to push back against you. Imagine sticking your hand out of a car window while driving – you can feel the air pushing back against your hand.

Now, imagine if you were a fish swimming through water. As you move, the water wants to push back against you, creating a sort of "pushing" pressure, which is called dynamic pressure.

This pressure gets stronger the faster you move. The faster you swim, the harder the water pushes back against you. The same thing happens to airplanes when they fly – the faster they go, the harder the air pushes back against them.

So, dynamic pressure is the pressure created by a fluid when an object moves through it, and it's a bit like the water pushing back against you when you jump into a pool.
