Learn how to read and interpret velocity vs. time graphs in physics with Khan Academy's comprehensive tutorial.
David explains how to read an acceleration vs. time graph. He then shows how the area under the curve gives the change in velocity and does a few examples.
Learn about acceleration vs. time graphs in physics, including how to interpret and analyze them.
Although speed and velocity are often words used interchangeably, in physics, they are distinct concepts. Velocity (v) is a vector quantity that measures displacement (or change in position, Δs) over the change in time (Δt), represented by the equation v = Δs/Δt.

Let's learn how to calculate accelerations from velocity-time graphs. We will also get some intuition behind why slope or steepness of a velocity-time graph represents acceleration.
