1. Wednesday, Sept. 10, 2014 Do Now: Yesterday we did this -

2. DISTANCE-TIME GRAPHS  A distance-time graph tells us how far an object has moved with time.  The steeper the graph, the faster the motion.  A horizontal line means the object is not changing its position - it is not moving, it is at rest.  A downward sloping line means the object is returning to the start.

3. And we drew this Speed-Time graph:

4. SPEED-TIME GRAPHS  A speed - time graph shows us how the speed of a moving object changes with time.  The steeper the graph, the greater the acceleration.  A horizontal line means the object is moving at a constant speed.  A downward sloping line means the object is slowing down.

5. By the end of the day today, IWBAT… Analyze characteristics of graphs and interpret differences in velocity & acceleration. By the end of the day today, IWBAT… Analyze characteristics of graphs and interpret differences in velocity & acceleration.

6. Wednesday, 09/10/14 TEKS: P.4A: Generate and interpret graphs describing motion including the use of real-time technology; By the end of today, IWBAT… Analyze characteristics of graphs and interpret differences in velocity & acceleration. Essential Question: How do we read motion graphs that show the position vs. time for an object? Topic: Motion Graphs C-Notes!

7. Graph Matching Activity  You have several graphs in front of you  Select the Information that accompanies each graph and match them together  Once you have the correct matches, you will create a notebook foldable to study

8. If You haven’t finished your Post-It note Fold-Ups!  On the Post-It Notes, draw the graph outline, then stick onto a piece of paper.  Underneath, write the important facts about the graph.  You can flip up the Post-Its when you study, checking the details for each graph underneath.

9. Create Your Own Graphs  Now create your own situations to graph – use a runner, a car – whatever! Then the class will draw:  a DISTANCE vs. TIME GRAPH  a VELOCITY vs. TIME GRAPH

10. Create Your Own Graphs  Create two graphs that show a runner’s path: He travels UP a STEEP hill, then DOWN a STEEP hill, then ACROSS a FLAT plain. Think about what he would look like and make:  a DISTANCE vs. TIME GRAPH  a VELOCITY vs. TIME GRAPH

11. The Unit2 Cover Sheet goes into your journals to keep track of your completed daily work prior to the exam. Record all assignments and keep it together. YOUR FIRST BINDER CHECK IS ON FRIDAY! Unit 2: 1D Kinematics Cover Sheet Don’t Forget Your
