Newton's Second Law (Edexcel A-Level Mathematics): Flashcards

Force applied to the object

Resultant force

A force must be applied

Zero (no resultant force)

$F = ma$

$9.8 \, \text{ms}^{-2}$

Larger force - smaller force

Draw a free body diagram

$F_x = F\cos(\theta)$, $F_y = F\sin(\theta)$

$\sum F_x = ma_x$ and $\sum F_y = ma_y$

$a = \frac{F}{m}$
