Scalars & Vectors (AQA A-Level Mathematics): Flashcards

A quantity with magnitude only, no direction

A quantity with both magnitude and direction

Speed, distance, time, mass

Velocity, displacement, force, acceleration

The magnitude of the vector

Place vectors head-to-tail, draw resultant from tail to head

Vector representing combined effect of two or more vectors

Changes magnitude but not direction

$R = \sqrt{A^2 + B^2}$

$\tan \theta = \frac{\text{opposite}}{\text{adjacent}}$
