Monday, September 8
- Chapter 1 Quiz
- Introduction to Domino Effect lab
- Introduction to Chapter 2 - What we'll be studying - units of motion (speed and its units)
Tuesday, September 9
Wednesday, September 10
- Finish the lab: The Domino Effect
- Finish your graphs in class and be sure to attach your graph to the lab report
- Discuss The Domino Effect lab
- What if we used 100 dominoes instead of 50? What would the time/distance/speed be?
Thursday, September 11
- Relative speed demonstrations:
- rivers with tanks
- gutter river
- What other forms of relative motion can you think of?
- Speed vs. velocity (formula, and units for them)
- instantaneous speed vs. average speed
- constant velocity vs. changing velocity
- Bring your calculator to class with you from now on!
Friday, September 12
- Domino Effect lab due
- Do next time question 2-2 and.... you ride a bike up the front hill (0.5 mi) at a speed of 2 mph then ride back down at a speed of 32 mph. What is your average speed?
- Example problems:
- A car's odometer reads 3962 km at the beginning of a trip and 4004 km at the end of the trip. The trip takes half an hour. Calculate the average speed.
- A bird flies at a speed of 14 m/s for 5 minutes. What distance did the bird fly?
- A snail travels 2.3 m in 2 hours. What is its speed in m/s?
- Work on homework problems
Monday, September 15
- P. 26; 26–27, 42, 45 due
- Look at composite Domino Lab data
Thursday, September 18
- Return and review homework
- DVD videos on #1 and #2 to see linear motion, relative motion and acceleration examples
- Acceleration and its units (a rate of a rate)
- (circular motion)
- Show how to do acceleration problems...
- What is your final speed if you start at rest and accelerate at 3 m/s2 for 4 seconds?
- What distance did you travel?
Friday, September 19
- Free fall (a=g=9.8 m/s2)
- Do Concept Development Practice Page 2–2 in class together
- You drop a ball from the school's roof. The roof is 11 m above the ground. Calculate the fall time and final speed as it hits the ground.
- A car is moving at 20 m/s when the driver decides to accelerate at 2 m/s2. What is the car's final speed and how far does it travel in this time?
- Mary jumps straight up with an initial speed of 4 m/s. What is her hang time? How high does Mary jump?
- Work on homework in class
Monday, September 22
- P. 26, 28–33, 49–50 due
- Go over problems in class
- Galileo's Ball Rolling Experiment
- Air resistance and symmetry of the motion of a ball being tossed up and falling
Tuesday, September 23
- Chapter 2 Review Due
- Go over in class and answer final questions
- Extra practice problems are found on page 661 answers
Wednesday, September 24
- Free Fall lab due
- Next Time question: Plane with crosswind
- Be sure you have read Chapter 3 by today
