Study Notes
Density Calculation
- Definition: Density is the mass per unit volume of a substance or object.
- Formula: Density (ρ) = Mass (m) / Volume (V)
- Unit: Typically measured in grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³)
- Example: Calculate the density of an object with a mass of 100 g and a volume of 50 cm³: ρ = 100 g / 50 cm³ = 2 g/cm³
Fluid Pressure
- Definition: Fluid pressure is the pressure exerted by a fluid (liquid or gas) on an object.
- Formula: Pressure (P) = Force (F) / Area (A)
- Unit: Typically measured in pascals (Pa) or pounds per square inch (psi)
- Factors Affecting Pressure:
- Depth: Pressure increases with depth in a fluid due to the weight of the fluid above.
- Density: Pressure is proportional to the density of the fluid.
- Gravity: Pressure is affected by the strength of the gravitational field.
- Pascal's Principle: A change in pressure at any point in a confined fluid is transmitted equally in all directions throughout the fluid.
