Monday, 9/16--more graphical analysis

Hi everyone, sadly I am out and ill today.  Boo.  That being said, this is a good time to get everything settled in your head.  If you have not handed in the 2 problems from Friday, you should do so

Last week, we read these three sections.  Refer to them as we think about things today.

Part 1:  Today, you should be asking a simple question.  What patterns are present?
In short, you should be able to articulate (and hand in, at the end of class) the following:

• if a d-t graph has a horizontal line, what will happen with the v-t graph?
• if a d-t graph has a line with a constant positive slope, what will happen to the v-t graph?
• if a d-t graph has a line with a constant negative slope, what will happen to the v-t graph?
• if a d-t graph has a curve, what will happen to the v-t graph?
• what are the corresponding dot diagrams for each of these above situations?  
• how are dot diagrams used to help us create d-t graphs
• how are dot diagrams used to help us indicate v-t graphs
• what does the dot on a dot diagram represent?

Part 2: Complete and hand in the worksheet that is on my desk.   You will need to draw a d-t graph in the space below the question, and a v-t graph to the side.

Part 3:  Pick 4 of the first 6 problems at http://www.physicsclassroom.com/calcpad/1dkin/problems.cfm and create a d-t graph and a v-t graph for them. (these are due Wednesday)

Part 3:
