| Property | What it means | Example | |----------|---------------|---------| | | How much mass fits in a given volume | Lead is dense; cork is light | | Viscosity (μ) | A fluid’s resistance to flowing | Honey has high viscosity; water has low viscosity | | Pressure (P) | Force spread over an area | A sharp knife (small area) cuts easily |

❌ ✅ Even in connected pipes — if you raise one end, all connected water adjusts level.

A is anything that flows . This includes both liquids (water, oil, blood) and gases (air, steam, helium). Unlike a solid, a fluid has no fixed shape — it deforms continuously when you apply a force.

So next time you see a plane overhead or spill your coffee, take a moment to appreciate the invisible forces pushing, pulling, and flowing all around you. You just mastered the basics of fluid mechanics

The "thickness" of the fluid. Honey has high viscosity; water has low viscosity. 3. The Big Three Principles

The (simple version):

Pressure increases with depth. This is why dams are thicker at the bottom than at the top—they need to withstand that crushing pressure.

Inside the shower, the air pressure drops. Outside the shower, the air is still and the pressure is normal (high). The higher pressure outside pushes the curtain toward the lower pressure inside .

You don’t need a PhD in physics to understand how liquids and gases move. In fact, you interact with fluid mechanics every single day—from the air rushing over your car to the coffee pouring into your mug.
