Study Notes
Pressure and Force
- An increase in the area over which a force is distributed results in a decrease in pressure, as the force is spread out over a larger area.
- Pressure is directly proportional to force, but inversely proportional to the area over which the force is applied.
- The relationship between force and pressure can be mathematically expressed as pressure = force / area.
Units of Pressure
- The SI unit of pressure is the Pascal (Pa), which is defined as one Newton per square meter (N/m²).
Test your knowledge about the relationship between force and pressure, the impact of increasing the area over which a force is distributed on pressure, and the SI unit of pressure.
