The goal for today's lesson is to apply that knowledge of work and energy (HS-PS3-3) in a lab activity. /Length 2761 Theory: The work-energy theorem states that the net (total) work done on a system is equal to its increase in kinetic energy. Use an organizational system and label all … You will ﬁrst consider the work done on a small point-like object by a constant force. (Answer shown below.) But in physics, we define work a little differently. (Opens a modal) Springs and Hooke's law. The concept of horsepower (the English unit for power) tells you how much energy a car generate in a given time period. They should be clearly organized and easy to find. Similar to work and energy, power is a scalar quantity. EXPERIMENT 6: WORK AND ENERGY Objective: To validate the work-energy theorem and to study the conservation of energy principle. Therefore, the power is calculated as follows. 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. 5 0 obj Learn. %PDF-1.3 So, for example, pushing a box with 10 Newtons of force for 15 meters is work. stream The Laboratory. Finish word problems Day 3: 11/15 1. Power. velisa October 17, 2016. Engineers must know how to calculate the power and energy needed to do the necessary work or provide the required heat. Work Notes 2. The work has linear relation with displacement. It is from its definition that power is the rate of doing work at specific displacement. 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. Work and energy can be considered as two sides of the same coin. 257,814 views This is so helpful, consice and easy. That energy can be measured by looking to the weight of the jar and the height of the incline. Watts. In doing so, we first need to define (review) some concepts. 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. /Filter /FlateDecode The following items should be in the Work and Energy portion of your notebook. Because energy is the capacity to do work , we measure energy and work in the same units (N*m or joules). Topics and Subtopics in NCERT Solutions for Class 11 Physics Chapter 6 Work Energy and Power: Section Name: Topic Name: 6: Work Energy and power: 6.1: Introduction: 6.2: Notions of work and kinetic energy : The work-energy theorem: 6.3: Work: 6.4: Kinetic energy: 6.5: Work done by a variable force: 6.6: 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. The work-energy theorem states that the net work done on an object equals the change in its kinetic energy. Reply. Like Like. Mathematically, work is represented by: In Concepts Energy, Work, Power Introduction Ever wonder if you can be more powerful that a Ford Mustang? Spierings, Spring 2012, Physical Science, Motion/Force - Work, Power, Energy.

The unit used to measure work and energy is a joule. Energy stored in an object is its potential energy as a result of its position. Here in this topic, students learn more in detail about work, power, force, energy and how are they interrelated to each other. If she applied a 650 N force during that time with the same power output, how far did she swim? •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. << /Length 4 0 R /Filter /FlateDecode >> 8.01x - Lect 11 - Work, Kinetic & Potential Energy, Gravitation, Conservative Forces - Duration: 49:06. 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." Force exerted on an object that causes it to move. One of the most important concepts in science is energy. Work is defined as a force applied through a displacement in the direction of the force. Finish Workout Lab 2. Work and Power Concept Check Day 4: 11/16 1. Review simple machines 2. Work and Power Newton's Laws, and dynamics as a whole, provide us with fundamental axioms for the study of classical mechanics. They will make you ♥ Physics. Laboratory #5 Energy, Work, and Power Part A. I am More Powerful Than a Ford Mustang! And for doing work energy is required. In this article, we will learn all about the concept of work, power and energy. For the experiments done here, energy can be measured according to the following formula: E = HW. How long does it takes a swimmer with a power output of 275 watts to accomplish 3600 J of work?. Work and Power 2. Work and Energy are closely related terms which are quite often used in our daily life activities. By converting our sims to HTML5, we make them seamlessly available across platforms and devices. Finish work and power notes 2. If we increase the displacement twice, work is also increasing twice. If you provide more examples and problems on work, energy, and power then it will be a great post. Work is a force applied over a distance. Here's how it's done. %PDF-1.4 The basic concepts of work, force, energy and power are fundamental physics concepts utilized in many engineering calculations and design. When we lift a book away from the center of dear old Earth, we do work on that book. Conservative forces. In this formula, E stands for energy, H stands for height above the ground and W stands for weight of the jar. Energy 3. SI units for power. Specifically, students will use spring scales to determine the mass of different objects (SP5) and then explore the relationship between work done and the mass of an object (SP3, SP4, & SP8).
