Vectors in 2 Dimensions (AQA A-Level Mathematics): Flashcards

Combining vectors to produce a resultant vector

Magnitude and direction

Combined effect of original vectors

Geometric (graphical) and algebraic (component)

Place vectors head to tail

From tail of first vector to head of last vector

$R_x = A_x + B_x$

$R_y = A_y + B_y$

$|\mathbf{R}| = \sqrt{R_x^2 + R_y^2}$

$\theta = \tan^{-1}\left(\frac{R_y}{R_x}\right)$
