The idea
Constant acceleration (suvat)
The five suvat equations, why they all fall out of the velocity–time graph (gradient = acceleration, area = displacement), and the one condition that makes them valid — constant acceleration.

Constant acceleration (suvat)
The five suvat equations, why they all fall out of the velocity–time graph (gradient = acceleration, area = displacement), and the one condition that makes them valid — constant acceleration.
Why it works
Five letters, one straight line
When acceleration is constant, the whole motion can be captured in a handful of formulas — the suvat equations, named for the five quantities they connect: (displacement), (initial velocity), (final velocity), (acceleration), (time). Every suvat question is the same game: three of the five are given, one is wanted, and one is missing.The entire set comes from one picture. Constant acceleration means velocity changes at a steady rate, so the velocity–time graph is a straight line — and straight lines are things you already know how to measure.
