Energy. Potential Energy: Gravitational & Elastic. Pendulum Motion. Energy Transformations . Human body . Automobile . Pole Vault and Bungee jumping. Nuclear power station. 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.. Changing Forms of Energy. Energy is most noticeable as it transforms from one type to another.. What are some examples of transforming electrical energy?. A lightbulb. A hair dryer. Changing forms of 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.. Kinetic Energy. Gravitational Potential Energy. Electrical Potential Energy. Internal Energy. Thermal (internal kinetic). Elastic potential (internal electrical). Chemical Potential (internal electrical). How is all energy divided?. . Potential. Energy. Kinetic. Energy. All Energy. Gravitation. Potential. Energy. Elastic. Potential. Energy. Chemical. Potential. Energy. What is Potential Energy?. Energy that is stored and waiting to be used later. Law of Conservation of Energy. aka. First Law of Thermodynamics. the . first law of thermodynamics.  is a version of the . law of conservation of energy. , adapted for . thermodynamic.  systems. The . I. Essential Question. How are Energy, Work, and Power Related?. What are the two main types of energy? . II. Key Vocabulary . Energy: . the ability to do work or cause change . Kinetic energy:. the energy of an object in motion. 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.. SUMMARY Seattle City Light contracted with Global Energy Partners Global to conduct a conservation potential assessment CPA to quantify the amount the timing and the cost of The CPAs objectives were t LO:. . We will understand that energy can take many forms but the total energy in a system is constant.. . CT: . I . will investigate and calculate the changes of different forms of energy.. . The Law . Conservation of Mechanical Energy. The Law of Conservation of Energy. The sum of the kinetic energy and the potential energy of the objects in a system is the system’s . mechanical energy . (. ME. ).. by new . new. Science Journal Entry 24. Define potential and kinetic energy, record their formulas, and tell how these types of energies are different.. Energy Conversion. Energy can be converted from one form to another. The process of changing energy from one form to another is called energy conversion. .
