Acceleration (Edexcel GCSE Physics Combined Science): Quizzes

Rate of change of velocity over time

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

When it speeds up or slows down

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

Change

$\Delta v = v - u$

Initial velocity

Size and direction

Object is slowing down (deceleration)

Velocity changes by the same amount in equal time intervals

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