Module 1 Discussion Post Newton John For this week’s discussion I chose to focus on terminology and application of units because at the beginning of the module I struggled with these two concepts and knew I was going to need to improve my understanding if I wanted to complete the assignments and have a good takeaway. There were multiple points brought out by our readings of chapter 1, such as quantities and units, relationships between speed, velocity, and acceleration and lastly some explanation into the different types of motions. While I most enjoyed some of the references to the drag racing industry and application, I wasn’t thoroughly surprised until reading some interesting facts observing reluctant velocity. Regarding this I have always been curious as to what the correct way to calculate velocity in an experiment where the object you’re on is moving fast enough to affect the overall speed performed by the person running (if using the example of the person on a boat as pictured in chapter 1 figure 1.11 and below) (Ostdiek & Bord, 2018). I would love to apply and understand how this resultant velocity is useful when considering flight and other exterior forces acting in a similar fashion to an aircraft. I could see this being applied to aviation specifically by calculating headwinds for example, which in theory should limit the takeoff ground speed and distance needed to perform a takeoff in otherwise calm conditions. This impact can be seen in how almost every airport is designed around the principles of having a headwind ideally head on for both takeoff and landing by increasing the ability of the wing without changing anything besides direction in order to trade off for needing

more airspeed for takeoff and less for landing. This application of resultant velocity is very easily applied to aviation when considering the mentioned variables as the vectors. I believe that these topics are extremely important because without some of these baseline understandings of how we observe objects moving and the units we use to track them then it becomes increasingly harder to grasp more complicated processes needed to solve aviation related problems that could arise. Having worked in aviation for over 10 years so far, I can say that almost every successful person I’ve met in the aviation industry really understands principles that we covered in the first module in relation to their field, whether that be measuring units, speed relationships, or even application of motion of aircraft. My field of aircraft weapons systems we were frequently converting units while overseas to properly notify nationals of withdraw distances for explosives and also applying concepts of speed relationships when doing G force reporting for our systems in place solidifying the importance and practicality of these for use at least in the military aspect of flight.
