PPT-Energy Energy Energy is the power to do work. It is measured in kilojoules (kJ) and kilocalories

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. 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:. 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). AP Environmental Science. What is Energy?. Energy is a . measurable quantity. that can be stored in a physical system. Energy can be . transferred. from one system to another and so . cause changes. 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. h. Use directly for hydro . energy storage . . Use the energy values to calculate the kilocalories (kcal) or kilojoules (kJ) for a food.. One hour of swimming. uses 2100 kJ of energy.. 3.5 Energy and Nutrition.

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 Energy transfer diagrams. Different types of energy can be transferred from one type to another. Energy transfer diagrams show . energy types in and out of a process.. Everyday Examples: Law of Conservation of Energy . One hour of swimming. uses 2100 kJ of energy.. 3.5 Energy and Nutrition.
