Work and Power Lab in Physics: Understanding Energy Conversion
This lab aims to demonstrate work production, energy storage, and converting work to power using steps, weight calculations, and time trials. Students record data, calculate work and power, analyze comparisons between individuals, and explore the concepts of work and power. Consistency, effort exertion, and understanding differences in energy expenditure are key focus areas.

Work & Power Lab SEO PHYSICS
Purpose 1. To demonstrate how work can be produced and have different storage of energy 2. To apply practice in converting work to power
Materials 1. Stopwatch 2. Meter stick
Roles (Group of 3 or 4) 1. Data Recorder = everyone in the group needs to record for each other 2. Stop Watcher= everyone in the group rotates using stopwatch 3. Measurer= Responsible measuring height of each stair
Procedures Find out your weight in lbs. 1) Multiply lbs. by 4.45 Newtons (N) 2) Use the meterstick to measure the height of one stair in meters 3) Find the total height by finding out the number of individual steps to multiplied by height of one step, in meters. 4) Record time per person going up or coming down, 5 times Total of 5 trials per person (time in seconds) 5) Switch roles with your peer and collect other persons time to go up 5 times BE CONSISTENT WITH ALL 5 TRIALS!!
Weight (N) Height of one step (m) Number of steps Total height of stairs (m) Time of climb 1 (s) Time of climb 2 (s) Time of climb 3 (s) Data Table #1 (per Individual) Time of climb 4 (s) Time of climb 5 (s)
Horse Power (FPS) Power (W) Work (J) Climb 1 Data Table #2 (per individual) Climb 2 Climb 3 Climb 4 Climb 5
Analysis 1) How do you calculate the amount of work done? the amount of power exerted? 2) What is the difference between work and power? 3) Two people climbed to the roof of a building. The old person walked up a gentle ramp. The young person climbed up a steep spiral staircase. Which person did more work? Explain 4) Were each of your trials climbing the stairs stay consistent in time change (seconds)? If not, Explain how it was different 5) Did you feel as if you exerted the same effort on each climb? Explain.
