WARM-UP
1. Look at the lab grading rubric below in agenda item #1. Which sections will I be assessing?
2. Find the error if your measured value for g is 9.95m/s2. (Recall that you looked up the actual value for g in Los Angeles on Day 18...)
CLASSWORK
1. #018B Penny Acceleration
Data Collection
While you collected data as a group, and can consult with group-mates to discuss errors and calculations, your lab write-up is your own work.
Grading Rubric LINK
2. Data Analysis / Conclusion
This is your own individual work. You can consult with your group-mates, you can share data with your groupmates, but the data analysis, conclusion, and error work must be your own. If I see copies among group-mates, points will be deducted.
- calculate average time
- calculate acceleration
- in your lab, you need to show one sample calculation. You can type this directly into the lab report
- Answer the conclusion questions in your lab report.
- we will have 20 min to work on your data analysis conclusion questions in class Thursday
***Some FAQ's on Significant Figures:
- Ruler is accurate to the mm. AKA 1.000m, so (4) sigfigs there
- Stopwatch on phones is accurate to the hundredth. AKA 0.44s, so (2) sigfigs there
- How many sigfigs in your final answer? (2)
- Should you round the time? (no)
- Should you round your final answer? (yes)
Learning at Home (HW)
- work on lab data analysis.
- review acceleration problem solving.
- if necessary, complete the below
#019C: Complete CH 3 pg 64 #7, 8, & 10 using the GUESS procedure, appropriate significant figures & units, and boxing your answer.

#Goals: SWBAT...
1. set up a free-fall problem in two dimensions with no outside assistance
2. solve a free-fall problem in two dimensions with no outside assistance
Warm-Up (5min)
Begin solving by doing G, U, and E from GUESS. Keep in mind that since this is a 2-dimensional problem, you'll need to separate your given/unknown/equation in an x-part and a y-part:
You accidentally throw your car keys horizontally at 8.0m/s from a cliff 64m high. how far from the base of the cliff should you look for your keys?
CLASSWORK
1. #20A: Complete the warm-up problem by Substituting the given info into the equation, and Solving. Don't forget to use the correct significant figures, and to box your answer.
2. #020B: "Practice Makes You Better" -Tiya M.
Set-up and solve a two dimensional free-fall problem
"A toy car runs off the edge of a table that is 1.225m high. The car lands 0.400m
from the base of the table.
a. How long did it take the car to fall?
b. how fast was the car going on the table?
TOMORROW:
3. #021A: Lab Procedure:
Write your lab procedure with your lab groups.
4. #019A: Warm-Up Check (con't)
I'm checking Days 10-19, for a total of 10 warm-ups and 20 points (2 points each)
At Home Learning (HW)
1. If you didn't finish your calculations for the placement of your target cup, your job is to finish those for Monday. On Monday, I will be available before school, during nutrition, and during lunch for those who still need to collect data, do math, or do their trial.
2. Complete #020B
