1. Calendar Mon., 12/8 Topic: Velocity-Time Graphs Homework: Finish any incomplete work between pg. 95 & 103 To Do Pick up 2 papers from the Pick Up table. The stapled packet is for tomorrow. Do not lose it. Make sure the worksheet of Velocity word problems & pictures is on pg. 99. Make sure the graphs of an ant from Friday is on pg. 101. Today, we’ll use pg. 102 & 103. 103 will be Cornell notes. 102 will be the worksheet. Get out Calendar Pencil Comp book Ruler (if you need it for your Cornell lines) FYI

3. Get out your ant worksheet from Friday and attach it to pg. 101, if it’s not already there. Let’s look at one of the problems to remind ourselves how to interpret a position-time graph Ant Worksheet (pg. 101)

4. Tell me the story of the mouse in this graph.

5. Accelerometer Walk with your accelerometer. What happens to the washer when you…? -Walk at a constant speed -Turn -Speed up -Slow down

6. Acceleration The rate at which velocity changes An object accelerates if its speed, direction, or both change An increase in velocity (speeding up) is called positive acceleration A decrease in velocity (slowing down) is called negative acceleration/ deceleration No acceleration is called constant velocity.

7. Acceleration Equation: Average Acceleration = final velocity – starting velocity time it takes to change velocity

8. Let’s do the Math with a word problem Example: A plane passes over point A at a velocity of 240 m/s north. Forty seconds later, it passes over point B at a velocity of 260 m/s north. What is the plane’s average acceleration?

9. Let’s do the Math with a Picture

10. Calculate acceleration for all 3 parts.

11. Calculate acceleration for all 4 parts.
