Document Summary
Our professor did not go over it in class, but my supplemental instructor did. Distance between to happenings on a common axis. Fundamental measure of how much stuff makes up an object. : mass is the same everywhere; whereas, weight changes depending on how much gravity is acting on the object. Density and speed are combinations of fundamental units. : other examples include joules, newtons, tesla, etc. Natural ideas that are represented as units are called dimensions. : distance = constant speed * time elapsed. : length/time is a derived unity > m/s. 30mi / 1 hr = 1hr / 3600 s = 5280 ft / 1 mi } the units reduce to ft/s (30*5280) / 3600 = 44 ft/s. Position = where something is in space relative to some reference point. Reference point is often used as the point of origin in a cartesian coordinate plane. Over a time interval, a moving object covers some distance.
