[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

Ah Seung Chong Molecular Biology CTW: Enzyme Kinetic Dr. Cruz 07/22/2010 Enzyme kinetics Introduction Enzymes are biological catalysts or assistants‚ without enzyme many of important processes of life could not happen. Most of enzymes are proteins that help speed up chemical reactions by lowering amount of activation energy needed for the reaction1. Enzymes are usually highly selective‚ only bind to specific substrate and convert it to product at a particular rate1. The rate of the reaction

Application of Energy ------------------------------------------------- Forms of energy Main article: Forms of energy Energy exists in many forms: Heat‚ a form of energy‚ is partly potential energy and partly kinetic energy. In the context of physical sciences‚ several forms of energy have been defined. These include: * Thermal energy‚ thermal energy in transit is called heat * Chemical energy * Electric energy * Radiant energy‚ the energy of electromagnetic radiation *

Micropower Energy Harvesting Abstract More than a decade of research in the field of thermal‚ motion‚ vibration and electromagnetic radiation energy harvesting has yielded increasing power output and smaller embodiments. Power management circuits for rectification and DC–DC conversion are becoming able to efficiently convert the power from these energy harvesters. This paper summarizes recent energy harvesting results. Introduction The low power consumption of silicon-based electronics

Flywheel energy storage works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. The energy is converted back by slowing down the flywheel.Flywheel energy storage system is one form of energy storage devices. It is basically a rechargeable battery. It is used to absorb electric energy from a source‚ store it as kinetic energy of rotation‚ and then deliver it to a load at the appropriate time‚ in the form that meets the load needs

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

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
