Power Lab- Upper Body

Purpose: Who in Mrs. Hunter’s ICPE has the most power in their upper body?

Hypothesis: Do you have more power doing a set of 5 push-ups or a set of 10 push-ups?

Procedure:

  1. Measure your arm length from your wrist to your armpit.
  2. Do 1-5 push-ups and enter the time it took in the table. (Part 1)
  3. Calculate the distance of your work by multiplying the number of push-ups you did by 2 and your arm length.
  4. Calculate your mass in kg.
  5. Calculate the force you push against the ground with.
  6. Calculate how much work you did.
  7. Calculate the power in your upper body.
  8. Do 5-15 push-ups and enter the time it took in the table. (Part 2)
  9. Repeat steps 3-7.

Data:

Person 1 / Person 2 / Person 3 / Person 4
Time to do 1-5 push-ups (s)
Arm length (m)
Distance (1-5 push-ups) (m)
Mass (kg)
Force (N)
Work (1-5 push-ups) (J)
Power (1-5 push-ups) (J/s)
Time to do 5-15 push-ups (s)
Distance (5-15 push-ups) (m)
Work (5-15 push-ups) (J)
Power (5-15 push-ups) (J/s)

Calculations:

D= (# of push ups) (2 X arm length in m)

2.2lbs. = 1kg

F=mg g = 9.8 m/ s 2

W=Fd (Work = force X distance)

P=w/t (Power = work / time)

Analysis:

  1. Did you do more work in part 1 or 2?
  2. Did you have more power in part 1 or 2?
  3. In you own words explain the difference between work and power.

Conclusion: (none needed)
