Acceleration (Edexcel GCSE Physics): Flashcards

Rate at which velocity changes over time

$m/s^2$

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

Change

$\Delta v = v - u$

Vector quantity (has magnitude and direction)

Object is slowing down (deceleration)

Velocity changes by same amount in equal time intervals

$v^2 = u^2 + 2as$

When time is not known

$u = 0$

Final velocity
