# Power Lab Report

Extracts from this document...

Introduction

David Urlanda Physics Lab Report Power Lab Purpose: To investigate what physical characteristics of students how it affect the power generated on running up the stairs. Hypothesis: The student that can generate the highest power would probably be Adam K, because it is so obvious that he's the most physically fit among every one of us. In addition, he's muscular and sporty. Variables and Controls: Independent Variable: the mass of all the students Dependent Variable: The force (Fg) Control: the vertical height of the stairs. Materials: Meter Stick Stopwatch Weighing Scale Calculator Procedure: 1. I made a table with columns name, Fg(N), Vertical Height (m), Work done, Power, Ranking 2. ...read more.

Conclusion

Sources of error: - The time could not be accurate; it's when one started running on late or advance time of the stopwatch. The runner must start at time the timer commands as he hits the stopwatch. Conclusion: Power is the time rate at which work is done. It is a measure of how fast you exert your energy. In this lab, it is Adam K. who has the largest power. Our physical properties affect the power we can generate. If we are heavy and fast we could generate high power. Because if you are athletic, you can do work in lesser time, as a result there is greater power. Example if you walk or run up the stairs, the power used is greater if you run up the stairs since you took less time. ...read more.

The smoother the surface the faster the block would move, and the lower the force of friction. Where as the rougher or bumpier the surface, the slower the block would move, and the higher the force of friction because more force was needed to move the object.
