Holt Physics—Chapter 5: Work and Energy Price I. Section 5.1—Work A. Definition of work 1. Work does not mean the same thing in Physics as it does in the everyday sense of the word. 2. Work is defined as a force causing a displacement. Work = force x displacement W = Fd 3. Work is NOT done on an object unless the displacement is greater than zero 4. The only forces that are considered to do work are those that

Solar Energy The Sun is a star and without it there would be no life on earth. This is why the Sun is called the ultimate source of energy. The Sun’s energy is produced by a process called nuclear fusion. Every second‚ the Sun emits vast amounts of energy‚ much of which is light‚ and this solar radiation can be converted into electricity. Plants and trees are pretty good at collecting this energy. With the help of green chlorophyll‚ they use light energy to make food – they’re our solar powered

Renewable Energy The use of renewable energy is probably one of the very few solutions for the energy needs of the future. It is considered as a form of safe‚ clean‚ and non terminating energy. In addition to all of that‚ renewable energy always brings marvelous economic benefits to any industry that uses it. Although renewable energy is expensive‚ time consuming‚ and less reliable sometimes‚ yet it still stands out as the solution for the energy needs of the future with respect to a safer environment

Energy Crises Energy is considered to be life line of any economy and most vital instrument of socioeconomic development of a country. Energy is pivotal in running machinery in factories and industrial units‚ for lighting our cities and powering our vehicles etc. There has been an enormous increase in the demand of energy as a result of industrial development and population growth‚ in comparison to enhancement in energy production. Supply of energy is‚ therefore‚ far less than the actual

Approaches to help allay such concerns include international fuel supply mechanisms and the possibility of a co-operative approach to nuclear power development within ASEAN. Southeast Asia’s nuclear energy aspirations connect with Australia’s role as a major world uranium supplier. Australia will also want to ensure that nuclear power in the region develops safely and in a context of international co-operation. This could involve using existing frameworks

Selection of Topic: Energy Crisis is a shortfall in or interruption to the provision of energy supplies. The planet is progressively marching towards a serious electric energy crisis‚ owing to an escalating desire of electric energy becoming greater than its supply. We have always accepted that the energy we make use of each day is not unrestricted‚ still we take it for granted. Coal‚ petroleum‚ electrical power‚ even water has inadequate availability. Nevertheless‚ we have not taken sufficient
