To use an example, imagine a scenario where you are driving in a car at 15m/s past a bunch of stationary pedestrians on the sidewalk next to you.
- From the pedestrian point of view, you and the car are moving at 15m/s forward. The pedestrian would be considered the stationary reference frame in this case.
- From your point of view, the car would be stationary as you are moving together with the car; however, the pedestrian would be moving 15m/s backward. You would be considered the moving reference frame in this case.
This illustrates how different reference frames can lead to different motions.
