Introduction to Graph

A graph is also a means to represent motion

Watch the following video for a glimpse of a graph.
 

Video 5.1: Introduction to Graph

You show two variables on these two axes respectively.                                                                                                                                                                 
In motion you deal with distance-time graph, displacement-time graph, speed-time graph, velocity-time graph and acceleration-time graph.
                                                                                               
On the graph, time is always represented on the X axis and distance, speed or velocity is represented on the Y axis in context of motion.

The relationship between these two helps you to discover the nature of motion.
