This document describes different types of motion on a speed-time graph. It shows an object at rest, moving at a uniform speed, with uniform acceleration and deceleration, and with non-uniform acceleration and deceleration. The graph illustrates an object's changing speed over time under different conditions of motion.

1. Speed-Time
