PPT-Unit 4: Work, Power, and Energy

Unit 4 Work Power and Energy I Work When a force acts upon an object to cause a displacement of the object it is said that work was done upon the object There are three key ingredients to work. Topics Covered. Energy Resources and Consumption. Energy Concepts. Energy Forms. Power. Units. Conversions. Laws of Thermodynamics. Energy Consumption. History. Industrial Revolution. Exponential Growth. In text: Ch 5. Do you already know these words?. Work – . Energy – . Power – . 2.3.1 Outline . what is meant by work.. First a demo:. One volunteer. Hold a couple of books and walk across the room.. Work . = W. The product of the force . F . applied to an object over a distance . d . in which the object travels as a result of the force. Joule . (J) . is the base unit of work. (Force and distance must be parallel to each other). Worldwide efforts to reduce energy consumption. People can conserve. Large percentage savings possible, but each individual has small total impact. Industry can conserve. Larger potential impact because of scale.. What’s the difference? . Definitions. Energy . is the ability to perform work. Energy is what allows us to . do . stuff. . Power . is the rate at which energy is transformed. . 1. st. Law of Thermodynamics. Lecture slides by. Mehmet .

Industry can conserve. Larger potential impact because of scale.. Datacenters are estimated to use 2 to 4% of the electricity in the United States. . Energy, Work, & Power SP3. Students will evaluate the forms and transformations of energy. a. Analyze, evaluate, and apply the principle of conservation of energy and measure the components of work-energy theorem by Work, Power & Energy Work Work is the product of force and distance For a force to do work on an object, some of the force must act in the same direction as the object moves. If there is no movement, no work is done. Regents Physics. Mr. . Rockensies. Introduction to Energy. How does energy manifest itself physically?. What is energy?. Energy is the ability to do . Work. .. Energy exists in several different forms. Almost all energy on Earth can be traced back to the Sun.. is essential for life, and is required to fuel many different body processes, growth and activities. . These include:. keeping the heart beating;. keeping the organs functioning; . maintenance of body temperature;. Unit costing is a method of costing based on units of production. It is also known as ‘output’ or ‘single’ costing. The . o. utput is measured in convenient physical units. It is a simple method of costing employed in industries where the production is continuous, uniform .
