Formula Triangles
Formula triangles show the relationship between different units (e.g. speed, distance and time).
Triangle
Triangle
- To find the quantity on the top row we multiply the two bottom quantities together (e.g. distance = speed × time).
- To find a quantity on the bottom row we divide the top quantity by the other bottom one (e.g. speed = distance ÷ time).
Speed
Speed
- Speed is the distance travelled per unit of time.
- Common units for speed are kilometres per hour (km/h), miles per hour (miles/h or mph) and metres per second (m/s).
Pressure
Pressure
- Pressure is force acting per unit of area.
- Common units for pressure are N/m2 or pascals (Pa).
Density
Density
- Density is the mass per unit of volume.
- Common units for density are kg/m3 and g/cm3.
