Energy Laws
Energy can be defined as the capacity to do work- but energy doesn’t just appear it must come from somewhere!
The first law of thermodynamics, sometimes known as the conservation of energy, states that:
Energy can be transformed (changed from one form to another), but cannot be created or destroyed.
The first part of this law refers to the transformation of energy from one into another. The second form may not be of use or be capable of being measured.

Forms of energy
Energy can exist in several forms and chemical energy is the most common. The energy is in the chemical bond that unites atoms or molecules with each other. When a new bond is made between two atoms, energy is required for its formation and this is usually in the form of heat, although light and electrical energy can be used. When a bond is broken and atoms are released, the energy in the bond is released as well. Heat, light sound, electrical and nuclear is other forms of energy.

Energy metabolism
The role of energy in the body
At this stage you may be wondering why there is so much emphasis on energy and be thinking that it is only concerned with muscular activity and movement. However, energy is also needed to circulate blood, lymph and tissue fluid throughout the body; it is necessary for breathing and taking in oxygen; it is necessary for making new cells and carrying out growth and repair; it is used to transmit nerve impulses so that we can respond to changes in the environment and it is needed to build different complex molecules such as enzymes and hormones from the simple molecules produced after digestion of food.
Anabolism and Catabolism
You have already learned about metabolism and how some chemical reactions involve breaking down molecules and releasing energy- these are catabolic reactions. The oxidation of glucose inside cells is a catabolic reaction and there…...

Electricity is essential part of our daily life and its outage has severely affected the economy and overall living of ours. Thousands have lost their jobs, businesses; our daily life has become miserable. Pakistan is currently facing upto 18 hours of electricity outage a day, is expected to face more if not dealt with in time. The purpose of this study is to analyze the nature of this crisis and to propose some short-term as well as long-term solutions to this problem. This study is exploratory in nature. We have done our best to conclude and sketch up some recommendations in the light of identified hurdles in the way of implementing the appropriate solution to our problem. Our study finds some major wholes in our system if they are covered up we can not only overcome the deficiency of electricity in our systems but also we can be able to export it to our neighboring countries. The basic flaws that our study identified are related to circular debt, and the inadequate capacity of our electricity production and distribution systems. Also we emphasized on some prospective alternatives......

Law of Conservation of Energy

...Law of Conservation of Energy: Statement: The law of conservation of energy states that the total amount of energy in a system remains constant ("is conserved"), although energy within the system can be changed from one form to another or transferred from one object to another. Gravitational Potential Energy: Definition: Gravitational potential energy is energy an object possesses because of its position in a gravitational field. Kinetic Energy: Definition: Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). Elastic Potential Energy: Definition: Elastic potential energy is Potential energy stored as a result of deformation of an elastic object, such as the stretching of a spring. It is equal to the work done to stretch the spring, which depends upon the spring constant k as well as the distance stretched. After defying of relevant theoretical terms here I am mentioning little comments on the given query. A real life example for conservation of energy is a ball falling from a building. The total mechanical energy is sum of equal to kinetic energy with addition of gravitational potential energy at different periods of time and height. The K.E. and G.P.E. is changing......

...GEOTHERMAL ENERGY Geothermal energy is one of the oldest sources of energy. It is simply using and reusing (reusable energy) heat from the inside of the earth. Most of the geothermal energy comes from magma, molten or partially molten rock. Which is why most geothermal resources come from regions where there are active volcanoes. Hot springs, geysers, pools of boiling mud, and fumaroles are the most easily exploited sources. The ancient Romans used hot springs to heat baths and homes, and similar uses are still found in Iceland, Turkey, and Japan. The true source of geothermal energy is believed to come from radioactive decay occurring deep within the earth. Electricity is one of the biggest outputs of geothermal energy. It was first recorded to produce electricity in 1904 in Italy. There are now geothermal power plants in operation in New Zealand, Japan, Iceland, the US and elsewhere. For the generation of electricity, hot water, at temperatures ranging from about 700 degrees F, is brought from the underground reservoir to the surface through production wells, and is flashed to steam in special vessels by release of pressure. The steam is separated from the liquid and fed to a turbine engine, which turns a generator. In turn, the generator produces electricity. Spent geothermal fluid is injected back into peripheral parts of the reservoir to help maintain reservoir pressure. If the reservoir is to be used for direct-heat application, the geothermal water is......

...Energy Portfolio management (Like Financial Portfolio management) is the Key to solving today’s and the future’s energy issues….. by Doug Story I believe it has been determined and accepted by almost everyone in the financial management industry and by those of us that invest or have our jobs supply financial instruments such as IRAs, Roth IRAs, 401Ks, etc for our retirement that it is imperative that our financial portfolio be diversified in such a manner that when part of the portfolio drops in value other parts of the portfolio will climb so that we may maintain, protect and continue to grow our funds in preparation for retirement. For example, why was the ENRON collapse such a disaster to most of the employees at ENRON? ENRON management had put pressure on everyone in the company retirement program to put all of their retirement savings into ENRON stock, so when the stock collapsed from its record highs these employees lost everything. If many of the employees at ENRON had invested in a diversified portfolio most of the money they placed in their retirement accounts may have been protected from the collapse of the ENRON stock. What does “Diversified Retirement or Stock Portfolio” mean? Simply put it means having a retirement account that is spread out over a range of stocks, bonds, cash and even precious metals. If the stock market goes down, in theory the bonds and precious metals will stabilize or go up at a rate that equals or reduces the losses due to the......

...In physics, the kinetic energy of an object is the energy which it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body in decelerating from its current speed to a state of rest. In classical mechanics, the kinetic energy of a non-rotating object of mass m travelling at a speed v is ½ mv². In relativistic mechanics, this is only a good approximation when v is much less than the speed of light. In physics, potential energy is the energy of an object or a system due to the position of the body or the arrangement of the particles of the system. The SI unit for measuring work and energy is the joule (symbol J). The term potential energy was coined by the 19th century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with a set of forces that act on a body in a way that depends only on the body's position in space. This allows the set of forces to be considered as having a specified vector at every point in space forming what is known as a vector field of forces, or a force field. If the work of forces of this type acting on a body that moves from a start to an end position is defined only by these two positions and does not depend on...

...down, charm, strange, top, or bottom. What can quarks be broken down to? Theoretical matter aka empty space. How do these things work? Energy, pure energy. When you break it down everything comes down to either empty space or energy. How do you control energy? You control energy with energy. There are several types of energy, but let’s start with the most basic. Good and bad. Good energy is when the energy you are using or the energy that is around is being used or put to a good purpose. Bad energy happens when the intent is to harm or negatively affect someone or something. You also have physical and mental energy. Physical energy is when you affect something outside of yourself, mental energy is what happens inside your own mind. There is potential for mental energy to become physical energy (like when your brain sends signals to muscles to move you) but one thing at a time. First let’s focus on bad energy. Define “bad”. Well: “bad-adjective-having undesirable or negative qualities.” Any type of energy can be “bad energy”. We all create bad energy every day. If we are angry at someone or angry at ourselves, that’s bad energy. If you hurt someone or yourself, that’s bad energy. Even if you are sad or upset that’s bad energy too. It all has an effect on our overall being. You can affect physical things with your bad energy by using mental energy that has been affected first. If your thinking is negative then any physical outcome it may have will be negative as well. For......

... “Energyconservation refers to efforts made to reduce energy consumption. Energyconservation can be achieved through increased efficient energy use, inconjunction with decreased energy consumption and/or reduced consumption fromconventional energy sources” ("Energy conservation," 2011). The twotypes of energy are renewable and nonrenewable. Renewable energy sources areconstantly renewed or restored and include wind (wind power), water(hydropower), sun (solar), vegetation (biomass), and internal heat of the earth(geothermal). On the other hand, nonrenewable energy sources are naturalresources that cannot be replenished. Fossil fuels such as oil, gas, and coalare the most commonly used types of non-renewable energy. However,non-renewable energy sources are being depleted at a rapid rate. In fact, (dueto this depletion) there may not be enough non-renewable energy sources forfuture generations. Additionally, (in this paper) I will discuss methods toconserve energy, save money, and help the environment as well. Because fossil fuels (such as oil,gas, and coal) are the most commonly used types of non-renewable energy, I willfocus on these types of non-renewable energy sources. “World energy consumptionhas increased every year since 1982, with most of the increase occurring indeveloping countries” (Berg, & Hager, 2007). “Additional energy demands inhighly developed nations may be met by increasing the energy efficiency ofthings like appliances, automobiles, and home......

...Energy Agnese Strayer University Dr. Andrey R. Pavlov Science 110 April 21, 2012 We recognize energy through the concepts of force and motion. When work is done on an object, it gains energy. Energy is made of two types, potential energy which is stored energy and kinetic energy which consists of moving energy. Food is stored energy. It is stored as a chemical with potential energy. When your body uses that stored energy to do work, it then becomes kinetic energy.(Integrated Science, 2008) Any form of energy can be converted to another form. Most technological devices that we use are recognized as energy converters. Energy cannot be created, nor destroyed. This is the reason why it exists in many forms. For example, a light bulb converts electrical energy to radiant energy. It can come in various forms, mechanical, chemical, radiant, electrical, and nuclear. Thermodynamics is the study of energy being converted from one form to another. There are three laws of thermodynamics. The first law states that energy cannot be created or destroyed, but it can be converted from one form to another. The second law states that heat energy can be transferred only from body at high temperature to the body at lower temperature. Heat can only be moved from high to low without external work being performed. If you want to move the heat energy from low temperature reservoir to high temperature reservoir, then something external must intercept in order for that to work.......

...Energy Fletcher Hinton Environmental Science Dr. Sandra Flemming April 6, 2012 Abstract This paper will discuss energy use and how it is conversed to do what it needs for the population using it. This paper will give an explanation on how energy use is dictated or regulated by law according to the energy policy act of (2005). Energy use is a major problem the world has today, resources are becoming scarce because of our consumption level is more than can be replenished in the amount of time we need it. The law of conservation of energy states that the quantity of energy stored in a system will be constant throughout time. (Law of conservation of energy, n/d) Since energy is stored it is constant it cannot be created or destroyed, but it can be converted into other forms of energy like solar energy, needs the sun to produce and harvest its energy. There are other forms of energy that can be used for our consumption and they are; fossil fuel: oil, natural gas, and coal, nuclear energy, Solar energy, Wind power, Water (hydro) power, Bioconversion (biofuel). Although, they can help produce energy there are pros and cons to using them for energy consumption. The fossil fuels for one are the most widely used source of energy used because of its reliable resources that can be converted. The con is it will run out because our consumption is more than the resource can produce. Nuclear energy produces 1/6 of the worlds electricity and it doesn`t produce......
