Jamie Tommy Jordan Work W F cosθ d OR W FΔr cosθ Work Example A person pulls a toboggan for a distance of 350 m along the snow with the rope directed 250 above the snow The tension in the rope is 940 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. Explaining the Causes of Motion in a Different Way. Work. The . product. of force and the amount of displacement along the line of action of that force.. Units: ft . .. lbs (horsepower). . Newton•meter. Work. Work is defined as the force parallel to the direction of motion times the distance.. W = F. (parallel) . . . d = F d . cos. . θ. If the direction of the force is opposite of the motion, the work is considered to be negative.. By: Aiden Cook, Kaitlyn Hemauer,. Abbey Loar, and . Elizabeth Rogers. How Does It Work?-Abbey. Nuclear Power Plants and fossil fuels are almost the same.. To keep the water under pressure you use a Pressurized Water Reactor. . 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. 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 . 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.. 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. IPC Spring . 2014. Energy, Work, Power & Machines. 1. Energy. is the ability to do work. .  . Potential energy. – stored energy or energy due to position.  . PE=m g h . m. is mass (kg). g. 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. . 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: 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 . 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.. 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..
