SUVAT Calculator — s = (u + v)t / 2

The fourth SUVAT equation uses a neat fact: under constant acceleration, the average velocity is exactly halfway between initial and final velocity.

$s = \frac{(u + v)t}{2}$

How to interpret the result

Displacement equals average velocity times time. A car accelerating from 10 to 30 m/s over 10 s covers (10+30)/2 × 10 = 200 m.
