Edexcel International GCSE Physics5b Density and pressure Checklist

Papers 1 and 2

• I know and can use the relationship between density, mass and volume: density = mass / volume, ρ = m / V
• Practical: I can investigate density using direct measurements of mass and volume.
• I know and can use the relationship between pressure, force and area: pressure = force / area, p = F / A
• I understand how the pressure at a point in a gas or liquid at rest acts equally in all directions.
• I know and can use the relationship for pressure difference: pressure difference = height × density × gravitational field strength, p = h × ρ × g
