Vectors (Edexcel GCSE Maths): Flashcards

Magnitude (size/length) and direction

a, b, c

Vector from point A to point B

$\begin{pmatrix} x \\ y \end{pmatrix}$

Direction stays the same

Magnitude changes

3 times the length, same direction

2 times the length, opposite direction

Same magnitude, opposite direction to $b$

Draw end-to-end; resultant from start to final end

$x$ units horizontal, $y$ units vertical

Multiply both parts by the scalar

Add top numbers together, add bottom numbers together

Opposite sides have equal vectors

Yes: $a + b = b + a$
