Equations of motion (AQA GCSE Physics Combined Science): Flashcards

When something changes its speed

Vector (has size and direction)

m/s² (metres per second squared)

$a = \frac{\Delta v}{t}$

How fast something moves in a particular direction

Vector (has size and direction)

$v^2 - u^2 = 2as$

9.8 m/s²

Gravitational field strength

Air resistance equals weight of object

Zero (forces are balanced)

Object slowing down or accelerating in opposite direction
