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.

What is so great about renewable energy? Well‚ because its renewable. Renewable energy will last forever and it cost close to nothing to get it. But it will always be their‚ unlike coal that once its gone‚ its gone. I think that the best process to get renewable energy is through geothermal plants. Some scientists think that the amount of geothermal energy stored in the earth will outlast our energy consumption and it may even outlast the sun. (Energy Informative) Geothermal is the most cost effective

Renewable energy is generally defined as energy that comes from resources which are naturally replenished on a human timescale such as sunlight‚ wind‚ rain‚ tides‚ waves and geothermal heat. Renewable energy replaces conventional fuels in four distinct areas: electricity generation‚ hot water/space heating‚ motor fuels‚ and rural (off-grid) energy services. About 16% of global final energy consumption presently comes from renewable resources‚ with 10% of all energy from traditional biomass‚ mainly

TIDAL ENERGY [pic] *75% of the planet’s surface consits of water. Our water supply transformed a barren planet into a lush green garden of life with a multitude of biodiversity. Water has easily fufilled our every need in many ways. As we near the twentyfirst century‚ a time when public attention is focused on the environment and society is increasing at an ever accelerating rate‚ the energy crisis continues to burden us. Questions of what to do about increasing energy demands and future requirements

Energy Alternatives: * Alternative energy is any energy source that is an alternative to fossil fuel. In a general sense in contemporary society‚ alternative energy is that which is produced without the undesirable consequences of the burning of fossil fuels‚ such as high carbon dioxide emissions‚ which is considered to be the major contributing factor of global warming. * This chapter discussed only a few of the possible alternatives to our current combustible energy generation system

Conserving energy is very important because there is a limited amount of nonrenewable energy sources available on earth such as coal‚ oil‚ and gas. If people do not conserve the nonrenewable resources we have now‚ there might not be any left for future generations. In addition‚ energy conservation is important because when nonrenewable energy sources are consumed this impacts the environment. The combustion of oil‚ gas‚ and coal in power stations produces carbon dioxide and contributes to global
