Newton’s second law (AQA GCSE Physics Combined Science): Flashcards

Change in motion: speed up, slow down, or change direction

Overall effect of all forces combined

Add together

Subtract

$F = ma$

Newtons (N)

Kilograms (kg)

Metres per second squared (m/s²)

Bigger acceleration

Less acceleration

Same direction as resultant force

Zero acceleration (constant speed)

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

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