The Conservation of Energy Essay - 712 Words

The Conservation of Energy Physics Essay: The Conservation of Energy Since the beginning of time, energy has pervaded our earth. These days we rely on it to advance in our technological developments. We also need energy for a variety of other things such as: to keep our bodies alive and healthy, to run our machines and other technical devices, we also rely on energy to keep warm in winter and cool in summer. Energy is the ability to do work. People and other things can run out of energy (e.g. a marathon runner) in which case they can no longer have the ability to do work. In a mechanical situation, if a machine has energy it has the ability to apply a force to another body. There are many different forms of energy and there are†¦show more content†¦Here is a description of the transformation of energy as a pole-vaulter completes a jump. Firstly, when the pole-vaulter runs forward the muscles in the legs are doing work as a result of energy to push him/her forward. As the pole digs into the ground and stops, the forward motion of the runner causes the pole to bend, giving it elastic potential energy. If the pole-vaulter were to let go of the pole at this point, the pole release upwards rapidly. As he/she jumps off the ground, it slowly releases the elastic potential energy of the pole and transforms it into kinetic energy, forcing the pole-vaulter upward and forward. If he/she ju mps too early, there would not be enough elastic potential energy created to force him/her over the bar. Also if the pole-vaulter doesn’t run fast enough, there will not be the required kinetic energy to force him/her forward over the bar. Conservation of energy also has another meaning and that is to ‘save’ energy. As the natural energy sources become scarcer it is important to learn how to save energy. One way of doing this is to create an energy efficient home. To create an energy efficient home there are many measures that can be taken to save energy, they include: solar energy, as the sun is a constant natural energy resource we can store that energy and use it to heat out water. ‘Sleep mode’ on computers, computers are definitely becoming more and more popular in homes,Show MoreRelatedEnergy Conservation1552 Words   |  7 PagesEnergy Conservation 1 Mitigation Strategies and Solutions: Energy Conservation Katie Shuker Axia College of University of Phoenix Energy Conservation 2 Energy conservation is the practice of decreasing the quantity of energy used while achieving a similar outcome of end use.

Patterson Axia College University of Phoenix March 7, 201 â€Æ' Introduction I am doing my essay on energy conservation. I would like to point out the good and the bad points of energy conservation. What could happen if we do not start conserving the different kinds of energy we have left? What are the different kinds of energy? How might we put into practice the different kinds of energy? In my paper, I will explain these formsRead MoreEnergy Project : Energy Conservation2197 Words   |  9 PagesEnergy Conservation in Android Using Computational Offloading Energy Efficient Downloader 1Abhijeet Panchal, 2Vishal Divekar, 3Bharat Bansode, 4Hasan Mujawar, 5Prof. Girish Navale 1,2,3,4,5 Dept. of Computer Engineering AISSMS’s Institute of Information Technology Pune, India Abstract: Development of new and innovative android applications made energy consumption a very important issue.

Most Americans do. The controversies in the Middle East and recent environmental disasters have made the cost of many natural resources, like oil, sky rocket. So imagine the amount of oil needed to power your car and compare that to the amount of oil needed to heat your home. Home energy conservation is a way that Americans can counter-act the estimated high costs to heat, cool or light their residence. In the ‘old days’ energyRead MoreEnergy Conservation at Home1164 Words   |  5 PagesWhat is energy? Where does it come from? And how do we pay for it?

Why you ask? Because of the limited amount of nonrenewable energy sources on Earth, it is important to conserve our current supply or to use renewable sources so that our natural resources will be available for future generations. Energy conservation is also important because consumption of nonrenewable sources impacts the environment. Specifically, our use of fossil fuels contributes toRead MoreThe Law Of Conservation Of Energy897 Words   |  4 Pagessubstitution (of himself). Because some of his creation had to be destroyed due to God’s desire to be relational, yet loathe of sin. God can not recreate himself (Law of Conservation of Energy: Energy can neither be created nor destroyed). There is only one God. That is why there is the law of conservation of energy- the energy therein can neither be created nor destroyed. This is what I believe. It happens to correlate with what author of engaging God’s world Mr. Cornelius Plantiga Jr. has to sayRead MoreEnergy Conservation Essay1345 Words   |  6 PagesThe topic of energy is one that is seen in the news more and more as each day passes. As most Americans can tell you these days, energy is essential for industrial and technological development in this or any other country. However, some believe that certain traditional methods of producing energy, such as burning fossil fuels, are depleting the earth’s limited supply of natural resources and may also be harmful to the environment. They encourage the use of renewable sources of power, such as wind
