PPT-Section 14 Work, Power, and Energy

More Power What does he mean Work Work is the product of force and distance For a force to do work on an object the object must move in the same direction of the force Any force that . Energy. The capacity of vigorous activity. The ability to act. The capacity of a body or a system to do work. (and heat). . . Mechanical Energy. Kinetic + Potential. E = U+K. . h. Chemical Energy:. 14) explain the relationship between work and power (using narrative and mathematical descriptions) and apply to realistic situations (GPS, HSGT) (SCPH_C2005-14). 14a) calculate the work on a body by constant force. 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). Homework:. Read . pages 257 – 260 . Answer questions p 261 # 1, 2, 3. P 262 #5, 6, 7, 8. Recall. :. A change in an object’s . momentum. is related to the amount of . time. a . force. acts on an object.. 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. Conservation of energy . Conservative and non-conservative forces. Chapter 8: Potential Energy and Conservation of Energy. Reading assignment: Ch. 8.1 to 8.5. Homework: QQ4, QQ5, AE7, AE8, AE11, 3, 6, 7, 10, 14, 15, 16, 22, 29, 40, 63. Section 1: Work and Machines. Section 2: Describing Energy. Section 3: Conservation of Energy. Section 1: Work and Machines. Work. – the transfer of energy that occurs when a force makes an object move. Principles of Engineering. Work. . Work. (symbol . W. ) is the energy transferred when a force . F. is applied to an object moving through a . distance . d. .. The SI . unit of work or . energy is the joule (symbol J).. 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, 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. Reminders about work and energy. 1 joule is equivalent to the energy required for a force of exactly 1 newton to act through a distance of exactly 1 . mete. r. Principle of conservation of energy. : energy cannot be created nor destroyed; it can only be transformed from one type to another..
