DAY 68
#Goals: SWBAT...
1. ...review the basic components of "Work" & "Power"
2. ...solve work and power problems
3. ...calculate the power output of a person climbing stairs
WARM-UP:
1. Haloke does 176J of work lifting himself 0.300m in 10s.
a. what is Haloke's mass?
b. how much power does Haloke develop?
CLASSWORK:
1. CW/HW Review
2. 066B: Power Lab
Chapter 10 pg 274-275: LINK
- overview
1. Which muscles will be the primary power generators in this lab?
2. For this lab, in which direction will work be done?
3. Would it make more sense to make your data table in Google Docs or Sheets?
4. How many rows and columns should you have in your data table?
Put your name/group names at top right, title top center
Create section titles for
Hypothesis (make a prediction: Which factors do you think affect power? Then answer the following: What can you do to increase the power you develop as you climb a flight of stairs?)
Materials
Procedure (in your own words)
Data (you need to make a data chart. it must have one row for each person in your group)
Data (you need to make a data chart. it must have one row for each person in your group)

Problems: 23, 24, 25, 26, 28, 29cd, 30a
WARM-UP
1. For each scenario, the red pulse and blue pulse interfere to form the green pulse. Decide if the two pulses create constructive or destructive interference
2. Use the concept of the Doppler Effect to describe why an ambulance siren changes pitch as it passes you.
