Uniform Acceleration Equations

Physics: IB Diploma Higher Level, topic 1.1.3

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

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

Test yourself on Uniform Acceleration Equations

Which equation for uniform acceleration is correct?
Which suvat equation does NOT contain displacement?
