Key Takeaways
Lesson Description
Key Takeaways
• Pressure is force applied over an area.
• Pressure increases with fluid depth.
• Objects float when buoyant force equals their weight.
• Density determines whether an object sinks or floats.
• Fluids flow from regions of higher pressure to lower pressure.
• Bernoulli's Principle relates pressure and fluid speed.
