Chapter 8 Copyright 2014 John Wiley amp Sons Inc All rights reserved 81 Potential Energy Potential energy symbol U is energy Joules Associated with configuration. You can join their conservation tradition right in your own backyard There are nearly 2 billion acres of land in the United States About 70 percent of that land is privately owned and care of that land is in the hands of those who live and work on it Objective: TSW understand, transfer and apply energy concepts to electric fields and charges by solving problems involving electric fields and forces.. Let’s revisit energy concepts for a gravitational field. A 250 gram baseball is thrown upward with an initial velocity of 25m/s. What is the maximum height reached by the ball?. ENERGY CANNOT BE CREATED OR DESTROYED, IT JUST CHANGES FORM. THERE ARE LAWS AROUND HOW ENERGY MOVES.. The Law of Conservation of Energy states that energy cannot be created or destroyed, it only changes from one form to another.. 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. Step 2: Assess Performance & Opportunities. Toolkit 2I: Water Conservation. Kentucky Energy Efficiency . Program for Schools. KEEPS Energy. Management Toolkit. Step 2. Assess Performance & Opportunities. A.S. 5.1.1 – 5.1.4 due Monday. Reading reference: chapter 16. Question 16.1a. . Electric Potential Energy I . a). . proton. b). . electron. c). . both feel the same force. d) neither – there is no force. Law of Conservation of Energy. : . Energy cannot be created or destroyed, only changed from one form into another.. Imagine a ball being thrown up into the air:. As the ball travels upwards . KE. is converted into . Potential Energy. Definition: The stored energy resulting from the relative positions of objects in a system. Potential energy is measured in Joules . 1 joule = 1 kg•m²/s². Ex. An apple is hanging from the branch of a tree. The energy that could potentially do work on the apple results from its position above the ground. What is Energy Efficiency and Conservation?. Energy Efficiency and Conservation is doing more with the same amount of energy or less energy.. Energy Efficiency and Conservation saves money and makes buildings more comfortable, healthy, and safe.. 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.. 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 . 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. . For an isolated system, energy can be transformed to different forms, but cannot be created or destroyed..
