| All motion requires a frame of reference, an origin from which to make measurements of displacement, and thus velocity, and so on. | All motion requires a frame of reference, an origin from which to make measurements of displacement, and thus velocity, and so on. |

| In many cases, you can take the origin as fixed and make all measurements from that origin. But what happens if you are in a plane, in car, or on a train? Below is a video made to demonstrate what happens when you compare measurements in fixed and moving reference frames. At the end of these notes, you will find formula that can be used to relate velocities measured in different references frames and a helpful pneumonic for remembering this equation. | In many cases, you can take the origin as fixed and make all measurements from that origin.
