How does my wind generator work? Every wind generator‚ whether they produce enough energy to power a city or to power a small radio‚ works on these same basic principles... 1. The wind blows 2. The generator’s vane (tail) causes it to turn into the wind 3. Blades attached to an alternator/generator experience the force of lift and begin to spin 4. The spinning creates electricity for us to use directly or to charge batteries Sounds pretty simple eh? Well‚ then how the heck do I build one

The Effect of Nuclear Energy on Human * As we all know‚ nuclear energy is a non-renewable energy. The science of atomic radiation‚ atomic change and nuclear fission was developed from 1895 to 1945‚ much of it in the last six of those years (WMA‚ 2010). Since then human have begun expanding their research on nuclear energy and sadly during year 1939 to year 1949‚ nuclear energy was only used for creating atomic bomb by many of the countries back then such as Japan‚ Germany‚ United States of

examples of work done=force x distance What is work? Work in physics is the transfer of energy; work is done on an object when an applied force moves it through a distance. The link between work and energy is work done equals energy transferred. The units for the two are also the same (joules). E.g. 500J of work = 500J of kinetic energy. Work is calculated with the formula: work done=force x distance moved For example‚ if a force of 10 newton (F = 10 N) acts along point that travels 2 meters
