Acceleration (Edexcel GCSE Physics Combined Science): Flashcards

Rate at which velocity changes over time

Metres per second squared ($m/s^2$)

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

Change

$\Delta v = v - u$

Initial velocity

Final velocity

Vector quantity

The object is slowing down (deceleration)

Velocity changes by same amount in equal time intervals

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