Coordinate Systems

One of the rare complications that can arise in the simple Because a difference in position is required when employing the Law of Change for the One-Dimensional Motion with Constant Velocity model is the issue of choice of coordinate system. Because a difference in position is required, it is important to carefully consider the problem statement, define a useful coordinate system and accurately assign the initial and final positions. The arbitrariness of choice of origin and direction int in the selection of coordinates is actually dangerous in a powerful feature of all the motion models, because too much freedom but it is important to remember that with great power comes great responsibility: failing to consider your coordinate system can lead to sloppy math.
