Work and Energy Ch. 6 Work = Force Distance Work increases the energy of an object. Energy can be converted back to work. Therefore, energy and work have the same unit: Newton meter = Nm Energy per gram, 3 Section 15.2 Conversion and Conservation (pages ) This section describes how energy is converted from one form to another and presents the law of conservation of energy. Reading Strategy (page 453) Relating Cause and Effect As you read, complete the flowchart to explain an energy conversion used by some gulls to obtain food. For more information on this Reading Strategy, see the Reading and Study Skills in the Skills and Reference Handbook at the end of your textbook. How Gulls Use Conversions Gull lifts oyster, increasing oyster s gravitational potential energy. The gull drops the oyster, and the oyster s gravitational potential energy is converted into kinetic energy as the oyster falls. (Air resistance can be ignored.) The oyster strikes a rock and breaks, and kinetic energy is converted into thermal energy. The kinetic energy and gravitational potential energy of the oyster are now zero. Conversion (page 454) 1. Is the following sentence or? can be converted from one form to another. 2. When a wind-up toy is set in motion, elastic potential energy that was stored in a compressed spring is converted into the of the toy s moving parts. Conservation of (page 455) 3.

One disadvantage of hydroelectric power is that it is among the most expensive energy sources. This activity can be completed over one or two sessions. Energy Literacy Principle 1: Energy is a physical quantity that follows precise natural laws. An energy resources that can be replaced in a reasonably short period of time is called a(n) Resource. 5. Have students set up their cities and companies. Name Class Date. You do twice as much work. b. You lift two identical books one meter above the ground. Work and Energy. Work = Force Distance. Work increases the energy of an object. Energy can be converted back to work. Energy Literacy Principle 2: Physical processes on Earth are the result of energy flow through the Earth system. energy obtained from sources that are virtually inexhaustible and replenish naturally over small time scales relative to the human life span. you can recognize by the changes it causes, such as motion and sound. NONRENEWABLE AND RENEWABLE RESOURCES. HMMMM. . Energy resources can be classified a renewable or nonrenewable What do you think nonrenewable resources. Ask: What happened to the energy resources in the simulation? Why? Do you think that we could really "run out" of energy resources? Explain that we have limited supplies of fossil fuels and that those fuels might become more costly and difficult to extract. Oh no! It looks like your browser needs an update.

Chapter 4 Forms of energy Introduction This chapter compromises a set of activities that focuses on the energy sources and conversion. The activities illustrate The concept and forms of energy; The different. What is Energy? What is the relationship between energy and work? Compare kinetic and potential energy What are the different types of energy? What is energy? Energy is the ability to do work. Great, but. What is Energy? What is the relationship between energy and work?. Create three charts on the board, one for each energy resource used in the simulation. Each chart should include a row for start, a row for each cycle, a column for "used," and a column for "left." Enter the data from the Energy Supply Charts for coal, oil, and natural gas. Have students use these data to create the graph described on the Simulation Reflection worksheet. Then have students answer the discussion questions below the graph. Get Energized! What are two types of energy? Energy is the ability to cause change. Energy takes many different forms and causes many different effects. There are two general types of energy: kinetic energy. when your muscles move, from the cereal you ate for breakfast is converted into. energy associated with the changes between atomic particles (electrons).

You can also check for student understanding during the discussion. Students should be able to describe how there were fewer energy resources available each cycle because students were using them up and they could not be replaced.

Reviewed by Marissa Shepherd, Instructor, Rogue Community College on 1/13/21. This is a measure of duration of an event. The SI unit for time is the second (s). Sub- multiples of the second are milliseconds, microseconds, minute, hour, day, week and year. It is measured using clocks, stop watches, wrist watches, and digital watches. E.g.

Girl, Wash Your Face: Stop Believing the Lies About Who You Are so You Can Become Who You Were Meant to Be. Earth's gravitational force is the force which pulls a body towards its center. This pull of gravity is called weight. Surface tension– this is the force which causes the surface of a liquid to behave like a stretched skin. This force is cohesive. No problems here. As I previously mentioned in the modularity section, the book is very organized and very easy to find the information especially if you use an online textbook. For my online chemistry class, I copy and paste the link of the specific chapters on the canvas shell page for my students to directly access it online. Force of friction– this is a force which opposes the relative motion of two surfaces in contact with each other. Friction in fluids is known as viscosity. I did not like that the intro to organic compounds, including describing functional groups, occurs in chapter 4: covalent bonding. Then in chapter 12, where organic chemistry really begins in earnest, the authors refer back to chapter 4. C. Lesson Planning Lesson planning is perhaps one of the most fundamental aspects that contribute to learning. Teachers have the responsibility to create conditions for students to get the most out of the language lessons.Thus, the lessons in the units follow predictable structure, namely Warm Up, Presentation, Practice, and Application. 1.WARM UP The purpose of the Warm Up stage is to assess students' prior knowledge, so that they become aware that they also have a lot of ideas to contribute to the class. Nevertheless, the teacher has to be prepared to start building either the content or vocabulary that students will encounter throughout the unit.Teachers are always encouraged to assess students' knowledge through activities such as short discussions, looking at pictures or talking about students' prior experiences. 2. PRESENTATION The Presentation stage is intended to get students familiar with either the vocabulary or the grammatical aspects in each of the lessons. The presentation introduces the context where students will use the language for most of the lesson's activities. 8 T 8 T Prelim_VP5IngGuideCol2012.indd 8 5/25/16 8:53 PM.

There are no obvious grammatical errors. The students in my class liked the way the book is written as it is very easy for them to read. For a professor who used publisher books in the previous years, this book might seem a little informal in writing. However, it doesn't bother me much, because as I won't require to read this as thoroughly as students since I am already familiar with the content over the years. This is the measure of the extent of a surface. It is a derived quantity of length. Its SI units are square metres (m2). Other units are cm2, km2, etc. Formulas are used to determine areas of regular bodies while for irregular bodies an approximation of area is used. Follow all instructions carefully and never attempt anything in doubt. 5. Use I guess to express your opinion about something you are not sure about. 1.

Consider the following diagrams; Reviewed by Chandra Kunapareddy Ph.D., Assistant Professor of Chemistry, Blue Mountain Community College on 1/6/20. The book was accurate. Most of the issues I felt came from issues of omission. This happened by not going into more depth on explanations of topics to help improve student comprehension instead of focusing on memorization based learning. Very small images especially in the biochem section detract from the experience and make it difficult to comprehend the material.
