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.
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.
Lesson 2: Straight-line motion: connecting position, velocity, and acceleration Introduction to one-dimensional motion with calculus Interpreting direction of motion from position-time graph
Watch this video to learn how to solve for time when you know the displacement, velocity, and acceleration of an object.
