![]() Warm Up: Let's talk about "free-fall" so we can discuss g's of spool car acceleration later on. 1g = 9.8m/s2, but for this exercise, let's round it to 10m/s2.Our task is to fill in all of the blanks on the right for a ball that is launched directly upward at a velocity of 40m/s.

![]() Warm Up: We're going to use this position vs time graph to find acceleration of the moving object.1 . What is the object's displacement between 0s and 1s?2. What is the object's velocity between 0s and 1s? 3. What is the object's displacement between 1s and 2s? 4. What is the object's velocity between 1s and 2s? 5. What is the object's displacement between 2s and 3s? 6. What is the object's velocity between 2s and 3s? 7. What is the acceleration of the object?

![]() Warm Up: I want to demontrate the types of motion on the right, using a cart on a track. I can tilt the track using books. How can I do each of these? Which ones are hardest? Let's assume for this activity that left is negative and right is positive. Today:

Warm Up: The graph on the right shows the positions at different times for seven different people, relative to a motion detector at the 0m mark. Which person (people) was (were)...

![]() Warm Up: 1 . On the velocity vs. time graph, find v0, v, and average v.2. On the position vs. time graph, find: total displacement, total distance, average velocity, maximum speed, and minimum speed. 3. Let's do some more practice to get ready for the quiz. Today:
Until Next Class: Have a great weekend! Review to retake the quiz if you want to. |
![]() Warm Up: Spin one of the "sprotating cylinders" by pressing one end until it squirts out from under your finger. Try pressing the other end. When the cylinder is spinning, why do you only see the symbol that you press? Today:
Until Next Class: Quiz next class, similar to today's practice quiz. You will get another chance to take the quiz and improve your grade. Quiz Learning Targets (highlighted in yellow, below): CVM.x - I can draw and interpret diagrams to represent the motion of an object moving with a constant velocity CVM.x - I can solve constant velocity problems CAM.x - I can draw and interpret diagrams to represent the motion of an object moving with changing velocity CAM.x - I can solve constant acceleration problems. CAM.x - I can solve kinematic equations

![]() Warm Up: How do dragsters go so fast?1. What kind of rear tires do dragsters use? 2. Why do drivers do a "burnout" before each race? 3. How else do dragsters increase traction? 4. What do dragster tires look like in slow motion? 5. Why and how do vehicles "pop wheelies?"
Today:
Until Next Class: Have a great Labor Day weekend!

![]() Warm Up: What is a spool car? How does one work? Today:
Homework: Think about this -- what thing moves at at constant velocity? The spool cars accelerate. What could we use in the classroom for collecting constant speed data?
