1256 - What is the definition of pressure and Pascal's principle?

Imagine you're swimming underwater. You might feel the water pushing on you from all sides. That's pressure.

Pressure is the force that pushes on something from all sides. It's like a strong hug. The more force that's applied, the more pressure you feel.

Now, let's talk about Pascal's principle. This is a rule that says: "When you apply pressure to a liquid (like water or air) in a closed container, the pressure gets passed on to every part of the liquid, equally."

Think of it like this: Imagine you have a big swim bladder under the water and you squeeze it. The pressure from your squeeze will be felt all around the swim bladder, not just where you squeezed it. That's Pascal's principle in action!
