Document Summary
It"s important to know where things are in both space and time. Physics explores not only position, but how position changes with time. In physics we use the symbol x for position in space with meters for units. You might be used to using "x" in other ways, but in physics it is reserved for position to keep things from getting confusing. To represent a displacement we subtract the inital position from the final position. We use the symbol to show change. X\delta x x = change in position, displacement [m, meters] vector xix_ixi = initial position [m, meters] vector xfx_fxf = final position [m, meters] vector. Example: mount everest is 8848 m above sea level. The base camp, where most mountain climbers begin their trek, is 5150 m above sea level. What is the vertical distance between the base camp and the peak? solution. Example: convert your answer from the previous problem into miles and kilometers.
