PPT-Work & Energy

AP1 Ch7 Or Why dont Taylor count HomeWORK as WORK Nitty Gritty Definitions Work A force acting through a displacement Work a force acting through a displacement F. 4. th. form IGCSE. Chapter 17 in textbook (p. 142). Reminder: work and energy. In the back of your book:. Define what is meant by . work. . and . energy. List different . forms of energy. N.B.:. NOT fuels…. Jamie,. . Tommy, Jordan. Work. W= F(. cosθ. )d . OR. W= . FΔr. . cosθ. Work Example. A person pulls a toboggan for a distance of 35.0 m along the snow with the rope directed 25.0° above the snow. The tension in the rope is 94.0 N. (a) How much work is done on the toboggan by the tension force? (b) How much work with the same tension parallel to the snow?. 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). Energy. The capacity of vigorous activity. The ability to act. The capacity of a body or a system to do work (and heat). . . Mechanical .

(symbol = . U. ) . is . energy . (Joules!). Associated . with . configuration. You . need energy to force an object to move. You need energy to make matter change. . The . blowing wind, the warm Sun and a falling leaf are all examples of energy in use. .. . Energy makes motion and change possible.. People can conserve. Large percentage savings possible, but each individual has small total impact. 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 Energy and Momentum Physics Unit 3 This Slideshow was developed to accompany the textbook OpenStax Physics Available for free at https:// openstaxcollege.org/textbooks/college-physics By OpenStax 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.. Why not?. Does energy just disappear? No!. Law of Conservation of Energy. : energy cannot be created nor destroyed.. -energy can change forms. 1. st. Law of Thermodynamics. : energy can do work, or produce heat, but it is always conserved.. 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;. Energy associated with forces that depend on the position or configuration of a body. Objects acquire potential energy when work is done on it. As an object loses potential energy, it can do work. Potential energy is the capacity to do work even if not doing work yet.
