L8-2 Lab 8 Work and Energy You will begin by comparing your intuitive, everyday understanding of work with its formal mathematical definition. Work and energy can be considered as two sides of the same coin. Therefore, the power is calculated as follows. Finish work and power notes 2. Theory: The work-energy theorem states that the net (total) work done on a system is equal to its increase in kinetic energy. 257,814 views In this formula, E stands for energy, H stands for height above the ground and W stands for weight of the jar. And for doing work energy is required. You will first consider the work done on a small point-like object by a constant force. /Filter /FlateDecode That is, when an external force moves an object through a distance it does work on the object which is evidenced by a change in its velocity or its kinetic energy, KE = ½mv 2. or, in symbols: In this lab, you let gravity do work on a dynamics cart and compare the work done on the cart to the cart's kinetic energy. The rate of doing work. Force exerted on an object that causes it to move. Work and Power 2. •To compare the total work on an object to the change in its kinetic energy as a first step in the application of the so-called Work-Energy Theorem. Terms in this set (17) Work. Work/energy problem with friction (Opens a modal) Conservative forces (Opens a modal) Power (Opens a modal) What is power? Gravitational potential … Here's how it's done. Work simulation and problems Day 2: 11/14 1. The Work/Energy Equation says "The work done on an object by the net force on it equals the object's change in kinetic energy." In this article, we will learn all about the concept of work, power and energy. EXPERIMENT 6: WORK AND ENERGY Objective: To validate the work-energy theorem and to study the conservation of energy principle. But memorizing the equation for work isn't actual workin physics. Power = Work Done = Energy used time time In the first part of this lab you will learn how the work done on an object is stored as potential energy of that object. Therefore, I conclude that work is related to power. PHYS 1030 General Physics I Lab – Work - Energy Principle In this lab you will perform an experiment to understand and analyze the relationship between work done on an object and the change in its kinetic energy. Work and Power Concept Check Day 4: 11/16 1. Review simple machines 2. The Laboratory. stream (Answer shown below.) 2 0 obj POWER (P) is the rate of energy generation (or absorption) over time:P = E/t Power's SI unit of measurement is the Watt, representing the generation or absorption of energy at the rate of 1 Joule/sec. Conservation of Energy Day1: 11/13 1. Every engineered device that moves, lifts or pushes requires energy. Rube Goldberg Project - this will replace a test, quiz, or lab score. When work is done on an object by a force acting parallel to its displacement the formula is: workdone = force x displacement For positive work to be done, F and s must be parallel and pointed in the same direction. One of the most important concepts in science is energy. About; Teacher Guide; Using Lab Notebooks; Share; The Photo Gallery. %PDF-1.4 They should be clearly organized and easy to find. I love this. Lab 3: Work, Energy & Power Essentials of Physics: PHYS 101 Most of us love the dear old Earth, in fact we’re quite attracted to it. Energy stored in an object is its potential energy as a result of its position. << /S /GoTo /D [6 0 R /Fit ] >> Mathematically, work is represented by: Concepts Energy, Work, Power Introduction Ever wonder if you can be more powerful that a Ford Mustang? %PDF-1.3 The Work, Energy and Power chapter of this course is designed to help you plan and teach the students in your classroom about the various forms of energy and power in physics. x��}�nɕ�{|E=Ȁ&�K����=32,�q J�HZT-���ߟ�K�Ȍ�,�Ur�$9/�}]{������ʯ�`��!�U�f(���J�9�>]�~^�W����f���J��������+��VZ��?�L�Wɕa|������7����Ǜ����_3�Y�y�z�_�[�����������f�&{���c�G^5�2>��������~9�Z�_�Չ��u�ژ��]�G7��x�fc~�y�G��z�YNB0f��\�Aq@���\x�Ȟ�k�s����n�qT�7�q�džeN>�2h�}ɓ�u��2e���m������aY֟wê���=/Κ)���1��Ȫ��&��W�I���}ȚI���^I��6rE��83I�O�3�O?����'���pE�h�A^>�պ���C;-4��-\���.�+QOW���W|$��q����.�q�+ Conservative forces. Lab 6.Work and Energy Goals •To apply the concept of work to each of the forces acting on an object pulled up an incline at constant speed. Go over Springs and Conservation of Energy Hwk: Continue working on Barbie Bungee; Extra Practice with Springs ; Answers (scroll down. In this lab you will examine three physical quantities: Energy, Work, and Power and the related units of measure. Now is your opportunity to find out! Work and Energy are closely related terms which are quite often used in our daily life activities. << /Length 4 0 R /Filter /FlateDecode >> The basic concepts of work, force, energy and power are fundamental physics concepts utilized in many engineering calculations and design. Equal to 746 watts. The work-energy theorem states that the net work done on an object equals the change in its kinetic energy. equal to Joules(J)/Time(s) Horsepower. endobj Reply. stream Learn. We do work because we must counteract its Work is a force applied over a distance. Work Notes 2. Work, energy and power are the most used terms in Physics. 9 0 obj << Gravitational potential energy and conservative forces. For the experiments done here, energy can be measured according to the following formula: E = HW.
