1. Three Steps To Graphical Analysis Graphs are one of the tools of the trade for Physicists. There are three basic things you can do with a graph. 1. You can __________off the graph 2. You can find ________ of the graph 3.You can calculate the _____ between the curve and the x-axis of the graph.

2. CLASS ACTIVITY Construct an accurate graph of the following data d(y) (m) -10.0-5.00.0+5.0+20.0 t(x) (s) 0.02.04.06.012.0

3. 1. What is the objects position at t = 3.0 ? 2. What is the change in position between t = 6.0 s and t = 10.0 s ? 3. Determine the slope of the graph using t = 0.0 s and t = 6.0 s. Repeat using t = 2.0 s and t = 12.0 s. 4. What property of motion is represented by the slope?

4. Slope Formula slope = rise = y 2 – y 1 = d 2 – d 1 run x 2 - x 1 t 2 - t 1
