Document Summary
Is the change in position, regardless of the actual path taken. It is a vector pointing from the initial position (xi , yi) to the final position (xf , yf). The si units (international system of units) are the meter [m]. Show and find rita"s displacement between 4 s and 8 s. In one dimension we can drop the vector notation. The average velocity during time t is given by: The instantaneous velocity is the time rate of change of position, i. e. the derivative of position with respect to time. If we choose a smaller and smaller time interval, then the average velocity becomes a better and better approximation to the instantaneous velocity. In one dimension: which is the slope of the s-versus-t curve at a given position. s stands for a given direction, say x or y or z or Only in uniform linear motion (i. e. constant velocity) is v = vavg.
