You're absolutely right! That's a key part of Archimedes' Principle.

Here's the full statement of Archimedes' Principle:

An object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.

Here's a breakdown:

* Buoyant force: This is the upward force that a fluid exerts on an object submerged in it.

* Weight of fluid displaced: This refers to the force of gravity acting on the volume of fluid that the object pushes out of the way.

In simpler terms: When you put something in water, it makes the water level go up a bit. The amount of water pushed out of the way is the same volume as the submerged part of the object. The buoyant force is the weight of that displaced water.

Let me know if you'd like more details or examples of how this principle works!
