Newton’s laws of motion (AQA A-Level Physics): Flashcards

Rest or constant velocity unless resultant force acts

Resistance of object to change its state of motion

$a$ proportional to $F$, inversely proportional to $m$

$F = ma$

Every action has equal and opposite reaction

Shows all forces acting on an object

$W = mg$

m = rac{W}{g}

a = rac{F}{m}

Direction of force; length shows relative magnitude
