Energy is the ability to do work. It is important because every object we produce requires energy; for example transport‚ growth‚ and development. Humans and all other things get energy from the sun. Some forms of energy are kinetic‚ potential‚ thermal‚ chemical‚ electrical‚ and mechanical. Kinetic energy is the energy of motion. Potential energy is the energy which results from a position or configuration. Thermal‚ or heat‚ energy is the energy a substance or system has related to its temperature

Energy Outline A. Benefits Of Solar Energy • Does not release green house gases • Production of solar energy does not produce smoke‚ gas‚ or any other chemical byproducts • Solar energy contributes to about 4 percent of the world’s electricity • Italy’s Montalto di Castro solar park: o good example of how solar contributes to the decrease in emissions o Decreases the carbon emissions by about 20‚000 tons per year compared to fossil fuel energy production. • Money! o Except for the initial

The Flow of Energy Stacey Ann Langston SCI/209 February 3‚ 2013 Cynthia Collin-Clausen The Flow of Energy The marine ecosystem relies on solar energy converted through photosynthesis by producers. Consumers‚ fish for example‚ metabolize‚ and release as chemical energy to convert into mechanical energy. The ecosystem distributes energy to living organisms through heat energy. Decomposers break down dead organisms and deplete them of their

atmosphere–ocean system and motivates the deeper examination to follow. The character of coupled atmosphere–ocean interactions is briefly introduced. Simple energy balance models are derived and used to illustrate the fundamental mechanisms behind variations of temperature with altitude‚ latitude‚ and season. The global annual mean energy balance is then presented and briefly discussed. Finally‚ the origins‚ thermodynamic structure‚ and composition of the atmosphere and ocean are summarized.

Kinetic Energy: Consider a baseball flying through the air. The ball is said to have "kinetic energy" by virtue of the fact that its in motion relative to the ground. You can see that it is has energy because it can do "work" on an object on the ground if it collides with it (either by pushing on it and/or damaging it during the collision). The formula for Kinetic energy‚ and for some of the other forms of energy described in this section will‚ is given in a later section of this primer. Potential

Examples of Radiant Energy The term radiant energy refers to energy that travels by waves or particles‚ particularly electromagnetic radiation such as heat or x-rays. Radiant energy is created through electromagnetic waves and was discovered in 1885 by Sir William Crookes. Fields in which this terminology is most often used are telecommunications‚ heating‚ radiometry‚ lighting‚ and in terms of energy created from the sun. Radiant energy is measured in joules.

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

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

Heat energy Temperature – measure of the average KE of the particles in a substance‚ measured in degrees Celsius or degrees Kelvin. Celsius 0⁰C (freezing point of water) to 100⁰C (boiling point of water) Kelvin 0 K (absolute zero‚ particles stop moving theoretically)‚ equivalent to -273.15⁰C. Uses the same scale for increase‚ ie. a 1⁰C increase in temperature equates to a 1K increase in temperature. Heat – amount of energy transferred‚ measured in Joules (J) Kinetic Energy‚ Thermal

Lab #7: Thermal Energy Heat is thermal energy being transferred from one place to another‚ because of temperature changes. This can take place by three processes. These three processes are known as conduction‚ convection‚ and radiation. When we place two objects with different temperatures in contact with each other‚ the heat from the hotter object will immediately and automatically flow to the colder object. This is known as conduction. Some objects make excellent conductors of heat while
