Uniform Acceleration Equations

These four equations describe motion along a straight line with uniform (constant) acceleration or deceleration.

Using the equations

Using the equations

You will often be asked questions involving the 5 key concepts of motion in a straight line:
- s, displacement
- u, initial velocity
- v, final velocity
- a, acceleration
- t, time
Usually you will be given three and asked to calculate a fourth using the 'suvat' equations, which are as follows...

The equations

The equations

$v = u + at$
$s =(\frac{u + v}{2})t$
$s = ut + \frac12 at^2$
$v^2 = u^2 + 2as$
