In this explainer, we will learn how to use displacement–time graphs and interpret the slope of the curve as the velocity of the body.
It works because displacement is the product of velocity and time. And in our graph when you multiply velocity and time you're basically multiplying two lengths in our graph and that gives us the area. And so that's the secret to calculating displacements and from a velocity time graph.

Displacement-time graphs show the displacement of an object from a fixed origin as it moves in a straight line. They show displacement (on the vertical axis) against time (on the horizontal axis) Displacement-time graphs can go below the horizontal axis whereas distance-time graphs can not.
An eagle is flying around and its velocity v as a function of time t is given in the graph below where rightwards is the positive velocity direction. What is the eagle's displacement Δ x from t = 1.0 s to 4.0 s ?
Displacement = Area under a velocity-time graph. Acceleration is any change in the velocity of an object in a given time. As velocity is a vector quantity, this means that if the speed of an object changes, or its direction changes, then it is accelerating.
1. Displacement-time graphs. Any point on such a graph has coordinates (t,s), in which s is the displacement after a time t. Worked Example 1. Figure 1 shows the displacement-time graph for a tennis ball which is thrown vertically up in the air from a player’s hand and then falls to the ground. The graph illustrates the motion of the ball.
