Forms of Energy CHEMICAL Energy Chemical energy is stored in the bonds between atoms. This stored energy is released and absorbed when bonds are broken and new bonds are formed – chemical reactions. Chemical reactions change the way atoms are arranged. NUCLEAR Energy Nuclear energy is the stored potential of the nucleus‚ or center‚ of an individual atom. Most atoms are stable on Earth; they retain their identities as particular elements‚ like hydrogen‚ helium‚ iron‚ and carbon‚ as identified

is their difference in momentum? What is their difference in kinetic energy? 2. A 12 g bullet is fired horizontally into a 96 g wooden block initially at rest on a horizontal surface. After impact‚ the block slides 7.5 m before coming to rest. If the coefficient of kinetic friction between block and surface is 0.60‚ what was the speed of the bullet immediately before impact? You have to use the conservation of the total energy of the system to do this problem: Initially‚ you have‚ in the total

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

Syria Chemical Crisis On August 21‚ near Damascus‚ chemical weapons were released on Syrian citizens. There is much debate on where the attack originated from. Some people think its rebels and others think it’s the Syrian government. They have estimated at least 1‚400 men‚ women‚ and children have died as a result of this attack. President Obama is deciding weather or not the United States will take action. Russian president Vladimir Putin has

Reusable Energy: The Cleaner and Cheaper Alternative Tom Harper HUM/114 July 15‚ 2013 Mark Spinler Reusable Energy: The Cleaner and Cheaper Alternative Over the past ten years‚ reusable energy has been the topic of so many law makers and just about every American tax payer around. As the energy rates continue to rise‚ we are constantly looking at new ways to save on household energy costs. We conserve energy by turning off lights‚ washing clothes during early morning or late evening hours

EDF Energy My individual seminar paper is written on EDF Energy. This is one of UK’s largest energy companies and its large producer of low carbon electricity. They generate around one fifth of the UK’s electricity. They supply electricity and gas to around 5.5 million residential and business customers‚ making them the biggest supplier of electricity by volume. The market segments they target; 1. They target individual home owners through SME. 2. They also target business organisations

Many researchers are trying to find new renewable energy sources to help diminish carbon emissions‚ which cause global warming. Carbon dioxide (C02) is released from human activities as well as using fossil fuel these are the causes of global warming and the green-house effect (European commission 2003). The release of green house gases has risen because of increasing population and technology development which has resulted in high demand for the use of fossil fuels. This is a serious issue in many

Global crisis occurs due to financial crisis and economic crisis. These are nothing but risk that could threaten humankind as a whole or even cause the end of planet Earth. A financial crisis is a situation where money demand quickly rises relative to money supply. A stock market crash is an example for this. Whereas economic crisis refers to the economic down of countries all over the world. They are going down in -ve zone. Global economy has become a hot topic for international forums

KINETIC ENERGY Objects have energy because of their motion; this energy is called kinetic energy. Kinetic energy of the objects having mass m and velocity v can be calculated with the formula given below; K=1/2mv² Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity‚ acceleration‚ force‚ and momentum‚ the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy‚ the standard metric unit of measurement for kinetic energy is
