Physics IGCSE Unit 5 – Pressure Already Graded A+

Physics IGCSE Unit 5 – Pressure Already Graded A+ 1. Definition of pressure... - Pressure is the force applied per unit area. 2. Pressure formula... - Pressure = Force divided by Area (P = F/A). 3. Units of pressure... - Pressure is measured in Pascals (Pa) or Newtons per square meter (N/m²). 4. Definition of density... - Density is the amount of mass per unit volume. 5. Density formula... - Density = Mass divided by Volume (d = m/V). 6. Units of density... - Density is measured in kilograms per cubic meter (kg/m³). 7. In a liquid, pressure increases... - As you go deeper. 8. Pressure difference formula... - Pressure difference = Height multiplied by Density multiplied by Gravity (ΔP = h × d × g). 9. Particles in a solid... - Are closely packed together and fixed in position.
