Speed, Density and Pressure (AQA GCSE Maths): Flashcards

$\text{Speed} = \frac{\text{Distance}}{\text{Time}}$

$\text{Density} = \frac{\text{Mass}}{\text{Volume}}$

$\text{Pressure} = \frac{\text{Force}}{\text{Area}}$

Distance travelled per unit of time

Mass packed into a given volume

Force acting per unit area

$\text{Distance} = \text{Speed} \times \text{Time}$

$\text{Mass} = \text{Density} \times \text{Volume}$

$\text{Force} = \text{Pressure} \times \text{Area}$

All involve dividing one quantity by another
