[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)

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

Li‚ 1 2-16-13 Solar Energy: The Energy of the Future Our Earth’s resorvoir of resources seem to be limitless‚ but with the exponential growth of the human population; the need for efficient alternative energy sources is becoming urgent. Therefore‚ research companies and individuals are focusing on creating new energy systems. Fossil fuels are are depleting and becoming more difficult to obtain. The earth will face an energy crisis in the near future if humans are not careful with their consumption

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

Energy conservation refers to reducing energy consumption through using less of an energy service. Energy conservation differs from efficient energy use‚ which refers to using less energy for a constant service.[1] For example‚ driving less is an example of energy conservation. Driving the same amount with a higher mileage vehicle is an example of energy efficiency. Energy conservation and efficiency are both energy reduction techniques. Even though energy conservation reduces energy services

Contents[Show] The energy of an object is its ability to do work. Energy is the cause and work is its effect. Therefore both work and energy have the same units‚ which is joule (J) in the SI system and erg in the CGS system. Energy is also a scalar quantity. Energy exists in many forms. Examples Mechanical energy which is either in the form of potential energy or kinetic energy or a combination of the both‚ electrical energy‚ light energy‚ thermal energy‚ nuclear energy and sound energy etc. Potential
