SOLAR ENERGY Our environment is in a fatal state any move could cost us the world. We need to work with the environment and not against it‚ we need to use what it is giving us every day and not every million year‚ once it is gone it is gone. Instead of using fossil fuels and having them burn to waste use solar energy and use what the sun gives us every day. Solar energy is an effective alternative source because there is very little pollution‚ they cut down on fossil fuels and are cost effective

Romar M. Cabinta EXERCISES 15 WORK‚ ENERGY‚ AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed.

ENERGY RESOURCE PLAN Conserving energy is important to our society because it can extend the life time of non-renewable resources. Examples of these are oils‚ coal ‚ and gas. It also minimizes the use of larger more dangerous and environmentally damaging sources ‚such as deep sea oil and tar deposits. Currently the world produces 20 million barrels of oil each year. One-third of that is used by the United Sates. Concidering that only %35 of an oil well can be recoverd one-third is a lot to consume

How does my wind generator work? Every wind generator‚ whether they produce enough energy to power a city or to power a small radio‚ works on these same basic principles... 1. The wind blows 2. The generator’s vane (tail) causes it to turn into the wind 3. Blades attached to an alternator/generator experience the force of lift and begin to spin 4. The spinning creates electricity for us to use directly or to charge batteries Sounds pretty simple eh? Well‚ then how the heck do I build one

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another‚ because of temperature changes. This can take place by three processes. These three processes are known as conduction‚ convection‚ and radiation. When we place two objects with different temperatures in contact with each other‚ the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while

Heat Heat is the transfer of energy from a hot object to a colder object‚ such as when toasting a slice of bread. The heat transfers onto the slice of bread which results in warm toast. When the slice of bread is heated‚ many things change; for example‚ the texture turns crunchy‚ the bread hardens‚ and the colour darkens. Where does the toast get its heat from? The toaster. Toaster A toaster is an electric small appliance designed to toast sliced bread by exposing it to heat. When a slice of bread

Topic: Energy Conservation By: Barry Auman Sci/275 The topic that selected is energy conservation because it is a big environmental problem that we need to work on to save the environment. This problem is very serious when energy is an expensive source and a very useful one. This problem causes environmental pollution and it needs to be reduced in order to make the earth a safer and healthier place. We all need to do our part to address this problem before it becomes worse. Energy conservation

(Mr. Goodman – Piranha 3D) It is no doubt that humankind have always thought themselves to be on top of the food chain. It is all about the survival of the fittest and although the humankind may not be able to out-run‚ out-swim or over-power certain animals in the animal kingdom they are able to invent devices which may assist them in being on the “top”
