PHY 114 Lab #8 - Mechanical Work and Energy Date: 11/13/2018
Objective: In this lab we explore the concepts of both work and energy and investigate the new concepts of kinetic and potential energy. Complete the data table given by using the materials provided and calculate the average time, velocity, kinetic energy, and potential energy of each. After this is finished a graph is to be plotted using kinetic energy vs. potential energy. This information will be found on the data table previously mentioned. The slope is then determined and some of the questions are to be answered. Principles/laws tested and used: The law tested in this Physics laboratory “Mechanical Work and Energy” was the Law of Conservation of Energy. This states that the total amount of energy in the world is constant. This means that energy can neither be created nor destroyed and that it can only be transformed from one form to another and redistributed between objects. The process of energy transformation and redistribution is called work. This week we tested both kinetic Energy and potential energy as well. Kinetic Energy is the energy or ability to do work, that an object possesses due to its motion. KE = MV^2/2, KE = M1V1^2/2 + M2V2^2/2. Potential Energy is the energy or ability to do work, that an object possesses due to its height or experiment. PE = M2gh Explanation of Procedure: This laboratory, titled “Mechanical Work and Energy”, is to teach how to calculate the times, average
