Next, she decelerates at a constant rate so that she comes to a rest at point B 3. Line graphs are used to show the relation of one quantity say displacement or velocity with another quantity such as time. Time is always plotted on the X-axis (bottom of the graph). At time t B, both trains have the same velocity. We will be studying three main types of graphs: Displacement – time (d-t) Velocity – time (v-t) Acceleration – time (a-t) But first, we will discuss some basic rules for graphing.
