Tuesday May 21 Overview Energy Motion Object Potential Mechanical Energy Chemical Elastic Chemical Gravitational Elastic Gravitational The nature of energy Energy of a spinning bicycle wheel Energy stored in food. Chapter 4 and 6. What is Energy?. You can experience it……. But you can’t directly see it…….. Nor can you directly hold it…….. But, you know it’s there!. In the 16. th. century, energy meant vigorous speech or writing, derived from the Greek and Latin words for “activity.”. What is energy? . ENERGY. is the ability to cause change.. There are many different kinds of energy.. Everything around us has energy – YOU have a large amount of energy.. When change occurs, energy is transferred from one object to another.. 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.. 1. Roller Coaster Physics. An exploration of . energy. . as it applies to the science of roller coasters. Draft Version. Boarding Information. 2. This. icon means that the slide corresponds to a page in the “Roller Coaster Physics Student Packet.”. Physics of Fun (26min). Energy. Any change in motion requires – . Energy. .. Work. is done when a . change. occurs.. Work. can’t be done without . energy. !. When an object or organism does work on another object, some of its energy is . QOD: What is the difference between potential and kinetic energy? . 1. . energy. – the ability to do work. energy is transferred by a force moving an object through a distance. when work is done on an object, energy is transferred to that object . You . need energy to force an object to move. You need energy to make matter change. . The . blowing wind, the warm Sun and a falling leaf are all examples of energy in use. .. . Energy makes motion and change possible.. th. . 1. Give two examples of heat convection.. 2. Describe specific heat in your own words.. 3. Which of the following substances heats up the quickest? . Aluminum = 900 c/J kg K . Copper = 390 c/J kg K . POTENTIAL. ELASTIC. CHEMICAL. GRAVITATIONAL. FORMULA.  . Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a . doubling. of the height will result in a . 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. 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 . How is work, power and energy related?. What is energy?. 2 types . Kinetic . Potential. 2. types . Gravitational . Elastic . Table of Contents . What are other forms of energy?. Mechanical. Thermal . I can define Kinetic and Potential energy.. I can identify Kinetic and Potential energy.. I can give examples of the two forms of energy.. I can explain how one can transfer to the other.. Work. The product of distance and the force in the direction an object moves..
