An object placed in water is "pushed up" by a force equal to the weight of the water it displaces. This is why you feel lighter in a swimming pool—the water is literally trying to carry you. 3. Bernoulli’s Principle (The Airplane Rule)
): Applied to fluids, this leads to the , which describe how the velocity, pressure, and temperature of a moving fluid are related. 4. Types of Flow
If you block half the opening with your thumb, you make the "door" smaller. To get the same amount of water through that tiny door in the same amount of time, the water has to speed up.
This is the cool part. This concept is called the , and it explains how airplanes fly. fluid mechanics for dummies
If an object is less dense than the fluid → floats. More dense → sinks.
Imagine a swimming pool. The water isn't moving, but if you dive to the bottom, your ears pop. Why?
If you spill water, it splashes everywhere. If you spill honey, it sits there like a puddle of sludge. The difference is . An object placed in water is "pushed up"
tells you which one you’ll get (high number = turbulence).
The main difference? Liquids are hard to compress (you can't squish water into a smaller ball), while gases are easy to compress (like pumping air into a tire).
❌ ✅ No — the atmosphere pushes things into low-pressure zones. Bernoulli’s Principle (The Airplane Rule) ): Applied to
Let’s break down the science of "stuff that flows" into bite-sized pieces.
Fluid mechanics is basically the study of how fluids behave when they move (or don't move). Here are the three concepts that explain almost everything.
