 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.**
