Density describes how much mass is contained within a particular volume. The relationship between density, mass and volume can be expressed using one formula, which can then be rearranged depending on the quantity that needs to be found. Density Density is calculated by dividing mass by volume: Density = mass / volume d = m / v What the Symbols Mean d = density m = mass v = volume Finding Volume Start with the density formula: d = m / v ⇒ dv = m v = m / d Volume = mass / density Finding Mass Starting again with: d = m / v ⇒ dv = m ...

Pressure, force and area are connected by a simple formula. Once the relationship is understood, the formula can be rearranged depending on which quantity needs to be found. Pressure, Force and Area The basic relationship is: To find pressure: P = F / A To find force: F = P × A To find area: A = F / P What the Symbols Mean P represents pressure. F represents force. A represents area. Units * Pressure is measured in pascals (Pa), where 1 Pa = 1 N/m². * Force is measured in newtons (N). * Area (A) is measured in square metres (m²). Understanding the Formula Pressure describes h...
