1. Work/Power in Climbing Stairs LAB [ use this as your title ]
Bellwork – 10/20/17
What do we need to know to find work?
What about the power required?

2. Work/Power in Climbing Stairs
How much work/power does it take you to climb stairs?
What do we need to know to find work?
Height, Weight ( the force needed )
What about the power required?
Time needed to climb stairs

3. Objective [ write down ]
In Graphing Notebooks!!!
Objective [ write down ]
Determine how much work/power is needed for you to climb stairs [ at a pace you choose ]?

4. Instructions
We are going outside to the softball bleachers to measure the power required to climb a few stairs
What do we need to measure this?

5. Instructions
We are going outside to the bleachers to measure the power required to climb a few stairs
What do we need to measure this?
Stopwatch, ruler, weight estimate

6. Instructions
Estimate your weight in pounds  convert to N by multiplying by 4.45

7. Data - What data do we need?

8. Data [ write down ] Your weight in Newtons ( lbs  N )?
Height of each step ( cm  m )? 0.2 m
How many steps? 4
Total height ( ignore horizontal movement )? 0.8 m
Total time?

9. Data Analysis / Conclusions [ write down ]
Total work?
Total power?
Graph of Force ( i.e, weight ) vs. distance. Show that the area under your curve equals the work you calculated above.
CONCLUSION/ANALYSIS QUESTION : how would your power value change if you climbed faster? Slower?
