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.

Finding distance and displacement from graphs. A baby elephant trots in a straight line along a river. The horizontal position of the elephant in meters over time is shown below.
31 mar 2022 · To prove that the area under this velocity-time graph is the object’s displacement, let’s start with figuring out the displacement. The equation for displacement is \Delta x=vt. In this case, we know v=5\text{ m/s} and t=10\text{ s}. Therefore, \Delta x=(5\text{ m/s})\cdot (10\text{ s})=50\text{ m}.
The displacement is simply the difference in the position of the two marks and is independent of the path taken when traveling between the two marks. The distance traveled, however, is the total length of the path taken between the two marks.
Use Figure 2.19 to (a) find the approximate displacement of the jet car over the time shown, (b) calculate the instantaneous acceleration at t = 30 s, (c) find the instantaneous velocity at 30 s, and (d) calculate the approximate average velocity over the interval shown.
One method for describing the motion of an object is through the use of velocity-time graphs which show the velocity of the object as a function of time. The area between the line and the time-axis on these graphs is equal to the displacement of the object. This page discusses how to calculate area so as to determine the displacement value.
Use distance to describe the total path between starting and ending points, and use displacement to describe the shortest path between starting and ending points.
