Newton's Laws of Motion (AQA GCSE Physics): Flashcards

Objects keep doing what they're already doing

Stay still unless pushed or pulled

Keep moving at same speed and direction

How hard it is to change how something moves

Harder to speed up, slow down, or change direction

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

Need more force to change their movement

Large needs harder push to accelerate as fast

Car harder to push - bigger inertial mass

Has smaller inertial mass than car

Light speeds up more, heavy speeds up less
