Abstract
This report aims to show how to determine the power output of going up a staircase and going down the same staircase, to determine the change in kinetic and potential energy of an object in free fall, and to demonstrate the conservation of mechanical energy.
1. Introduction
Work, power and energy are always in relation to each other for these three are always present in every motion that occurs. Work refers to an activity involving force and movement in the direction of the force. Meanwhile, energy is the capacity to do work. When one works, he or she exerts energy to be able to do that specific movement or motion. Additional to that, power is the rate of doing work or it is the rate of using energy. In this experiment, the objectives are as follows: to demonstrate conservation of mechanical energy, to measure change in kinetic and potential energy as a ball moves in free fall and to determine the power output when going up and down the stairs.
2. Theory
In this experiment, we will discover who is the most “powerful” person in the group by means of who does the most work. After getting the mass of each member, we will record their time in climbing down the third floor to the second floor and their time in climbing up the second to the third floor. After getting the vertical distance between the second and the third floor we then we then calculate which member exerted more work.
Formula 1. Formula to determine the weight of a person where m refers to the mass of the person in kilograms and g refers to the force of gravity, 9.8m/s2.
Work is the application of force on an object and the displacement of that
