[Energy resources]: The 2 broad types Pros and Cons of each type Ways in which they are harnessed There two main types of energy these are: 1. Potential energy 2. Kinetic energy Potential energy Potential energy is energy stored due to position. The following are some example in which potential energy can be found. 1. Wound-up spring When a spring of a dock work toy car unwinds‚ the stored energy in the spring drives the wheels and the car moves. The wound-up spring is said to posse potential

Maggie Haas Reiter Honors Physic 8 March 2015 Background Information: Anything that has mass and is moving has momentum. Momentum is equal to the objects mass times its velocity. Momentum is conserved‚ which means that “momentum before an event equals momentum immediately after‚ or pi=pf”. Since pi=pf‚ then pai+ pbi = paf+ pbf and (ma* vai)+ (mb* vbi)= (ma* vaf) + (mb * vbf). Having velocity simply means that an object has a speed and direction. Using the formula “(ma * vai) + (mb * vbi)

opinion. In which he sums everything up in his last paragraph by saying that everything is predetermined but might as well not be because how are we supposed to know what is determined if we actually never will. This is all said in his title of his essay which is actually the question he poses. However I feel that while Stephen Hawking is posing logical questions and then backing up his ideas and with logical and scientific support‚ why it should matter. I’m not saying he is wrong or right‚ but

We should not even consider the idea of participating in Screen Free Week because technology gives us access to helpful obtainable references and the ability to communicate with others efficiently. Without a doubt‚ there is no point in having a week stripped of our electronic devices. Schools should not participate

The Energy of the Future The United States of America is in desperate need of an alternate energy source. One such alternate source is nuclear power. Nuclear power is a form of energy produced by an atomic reaction‚ which is capable of producing an alternative source of electrical power‚ replacing the energy currently supplied by coal‚ gas‚ or oil. This will help the United States move away from burning fossil fuels and potentially reduce overall pollution. Nuclear power has the potential to be

Solar Energy Alternative energy resources are being closely evaluated because of the depletion of nonrenewable resources‚ such as fossil fuels. Fossil fuels and other nonrenewable resources have damaged earth because of the amount of pollution that is released some‚ in which is known as Carbon Dioxide. Massive amounts of Carbon Dioxide are that is released into our environment every year further damaging our planet. Scientist has been effectively working on ways of conserving energy that is

Energy Resources and their Uses in Producing Electricity Renewable energy is energy drawn from natural processes that are restored quicker than they are used up‚ some renewable energy resources are biomass‚ food‚ wind‚ waves‚ flowing water‚ solar and geothermal. The sun however‚ is known to be the ultimate energy resource since almost all energy resources originate from the sun’s energy. This is possible according to the law of conservation of energy which states that energy can’t be destroyed

Household energy consumption is examined in the specific context of home heating expenditures. Analysis of home heat costs across stages of the family life cycle reveals a distinctly different pattern than previously found when total household energy costs were examined. In contrast to the curvilinear pattern where expenditures peak during middle stages of the life cycle‚ these data show a positive linear relationship where higher costs are associated with elderly consumers. The research focus is
