PhyFl18SS1.7.18 This is a new type of graph for us. It is called a slope graph. It is also called a derivative graph. In this case it is a velocity vs. time graph. It shows what the five interval velocities of the trippin run. This is a VERY important screenshot. It is where we are going next and it is the beginning of your journey into graphical calculus. This graph is the derivative part of the x vs. t graph. Together they form red duets. An example of a weighted average for our step function can be seen by comparing the darker flat segment compared to the 5 orange segments. The darker segment is the weighted average of the 5 orange segments.
