Work and Power Developed: Creative Writing Lab Report

Experiment # 5:
Work and Power Developed
Introduction:
The concept of work deals with applying a force on an object which results in moving the object a certain distance in the same direction that the force was applied. In general, work is done against friction or against gravity. In this experiment we are going to calculate the work and power of a student walking up and running up a stairway. Since the student is lifting himself or herself through a distance that is parallel to the force due to gravity. Walking up the stairway, results in using energy at a lower rate than running up the stairs which produces, less power when walking up the stairway and greater power when running up the stairway. The rate at which energy is expended or the rate of work is known as power that is power is defined as work per unit time:
Power = Work/Time
Work = (Force) x (Distance)
The unit of power is watt using the metric unit and horsepower using the English unit and one horse power is equivalent to 746 Watts and 1 Kilo watts is about 1.5 Hp.

Objective:
To purpose of this lab is to calculate the power output of a student walking and running up the stairway.
Required Equipment and supplies:
Measuring tape, Stop watch, Bathroom scale and a calculator.
Procedure:
1 Using the bathroom scale weight you self in pounds and convert that to kilogram using the conversion factor one kilogram is equal to 2.2 pounds and record it in table 1
2 Multiply the kilograms by the acceleration due to gravity and record it in table 1. This will be your weight in Newton which represents the force needed by the student to lift him or herself up the stairway.
3 Measure and record the vertical height of the stairway in table 1. This can be done by measuring the height of one step and multiplying it by the number of steps that makes up the stairway.
4 Measure and record the time to walk up and run up the stairway and record it in table 1.
5 Using the data recorded in table 1, calcul...
