Graphs of Motion

Graphs are a visual way to present information.  It isn't easy to make graph, but it is easy to read them.  If you made a graph today in class you are pretty much done with that part.  However, lots of graph-reading to come.

Look at the two pictures below.  Which one lets you instantly see if tomorrow will be warmer or cooler than today?

The information in both pictures is the same, but the graph shows you the temperature trend.

See?  Graphs are useful.

Over the next several lessons we will be reading graphs that tell us about an object's motion.  If you did the bowling ball today, your HW tonight is "Speed Segment Graph HW" in the Linear Motion shared folder.  Your task is to look at each segment of the graph (A, B, C, D and E) and to find the speed during that time, as well as the distance traveled.  (There are also a few conversion practice problems thrown in).

How do you find the speed?  Use slope. The formula is there.  You'll see that when you find the change in y over the change in x and you include units, you'll end up with a unit of speed.  Use the information on the y-axis to find the distance traveled.  When you have an answer stop and ask yourself if it make sense.

Turn this into the Drive folder with your name when done.  Newtons, due Friday; Galileos and Einsteins due Monday.
