Advanced Placement Physics 2 focusing on fluids, thermodynamics, and modern physics.
Fluid dynamics studies fluids in motion. One of the most important concepts is Bernoulli’s Principle, which relates a fluid’s speed, pressure, and potential energy.
For incompressible, non-viscous fluids, the equation is:
\[ P + \frac{1}{2} \rho v^2 + \rho g h = \text{constant} \]
This means that where the speed of a fluid increases, its pressure decreases, and vice versa.
Bernoulli’s principle is used in designing aircraft, predicting weather patterns, and even explaining how soccer balls curve in flight.
\[P + \frac{1}{2} \rho v^2 + \rho g h = \text{constant}\]
An airplane wing generates lift using pressure differences.
A fast-flowing river has lower pressure at the surface than slow-moving water.
Bernoulli’s Principle connects speed and pressure in moving fluids, with broad engineering and scientific applications.
