how is energy related to work, force and power.?

Work refers to an activity involving a force and movement in the directon of the force. A force of 20 newtons pushing an object 5 meters in the direction of the force does 100 joules of work. \n\nEnergy is the capacity for doing work. You must have energy to accomplish work - it is like the "currency" for performing work. To do 100 joules of work, you must expend 100 joules of energy. \n\nPower is the rate of doing work or the rate of using energy, which are numerically the same. If you do 100 joules of work in one second (using 100 joules of energy), the power is 100 watts.

It's the theoretical relationship between energy and mass.  Albert Einstein's famous equation.  It is what nuclear power is based on.

Although the words are used in many ways, science has specific definitions\nfor each.\n\nForce is a push or a pull.  Force is between objects, one object pushing or\npulling on another.\n\nEnergy is more difficult to define, because energy is "abstract".  Energy is\na quantity that gives an object the ability to affect other objects.  There\nare different kinds of energy.  Kinetic energy is the energy of motion,\nstored within a moving object.  Potential energy is stored in the force\nbetween objects, perhaps in the stretch of a spring.  Thermal energy can be\nstored in the temperature of an object.  Energy passes from place to place,\nobject to object, but never disappears.  The total energy of the universe\nremains constant.\n\nFuel is a material that has energy stored in its chemical structure.  When\nfuel is processes (burned, for example), the chemical energy is released.\nThis released energy can become heat and cause the temperature of something\nto rise.  The released energy can become the kinetic energy of a car.  It\ncan become the energy carried by sound to your ears.

A Kw is a measure of energy and cannot be translated directly to any unit of pressure. It takes energy to create pressure and energy can be measured from a release of pressure, but the two are not congruent.

Work, power and energy all have the same units of measurement in SI scale

The potential energy of a system is the energy which was spent to constitute the system from bringing its constituents closer\nto each other against the forces among them and this energy is stored in the syetem. The same way the interatomic energy is \nthe enrgy which was spent to bring the atoms closer against the vanderwaal forces.

ENERGY--\n\n–noun, plural -gies. 1. the capacity for vigorous activity; available power: I eat chocolate to get quick energy.  \n2. an adequate or abundant amount of such power: I seem to have no energy these days.  \n3. Often, energies. a feeling of tension caused or seeming to be caused by an excess of such power: to work off one's energies at tennis.  \n4. an exertion of such power: She plays tennis with great energy.  \n5. the habit of vigorous activity; vigor as a characteristic: Foreigners both admire and laugh at American energy.  \n6. the ability to act, lead others, effect, etc., forcefully.  \n7. forcefulness of expression: a writing style abounding with energy.  \n8. Physics. the capacity to do work; the property of a system that diminishes when the system does work on any other system, by an amount equal to the work so done; potential energy. Symbol:. E  \n9. any source of usable power, as fossil fuel, electricity, or solar radiation.

kinetic energy is: the energy of a moving object. the formula for this is 1/2*mass*velocity^2 in symbols 1/2*m*v^2\nFormul description: the work needed to accelerate a body from rest to its current velocity\n\nLight enegry: I've never heard of light energy before now if ur talking about the brightestness of the bulb than that is called luminosity a buy product of lighting sources is also heat energy, transfer of light is also done by photons you could say these carry the light energy.\n\nPotential energy: is energy which depends on mutual positions of bodies. The energy is defined as a work against a specific force such as gravity, an elastic force of a spring in a clockwork motor, electric force, etc (and is usually named after that specific force).\n\nchemical energy: Is a form of potential energy due to the breaking and forming of chemical bonds.\n\nGravitational potential energy:  the potential energy per unit mass of an object due to its position in a gravitational field.\n\nHope this helps

Net force is required to change the motion of an object, or accelerate the object. Often forces are balanced, so net force = 0, so motion does not change.\n\nWork is in the same units as energy, not force. Work is related to force by \nW = F*d*cos(theta) where F is the applied force, d is the distance through which the force has been applied, and theta is the angle (if any) between the force and the distance. \n\nFor example if a 100 Newton vertical force is applied to lift an object to a table 5 meters above the starting point, 500 Newton*meters, or 500 joules, of work have been done.

Energy\n\nEtymology: Greek "energeia" activity, from "energos" active, from "en" in + "ergon" work

Mechanical energy basically consists of potential and kinetic energy.  Potential energy is "captured" energy that is ready to be released.  Kinetic energy is energy a body possesses as a result of its motion.\n\nEveryday objects are made of atoms and molecules.  Atoms have electrical charges.  Electrical charges repel or attract each other.  It has been theorized that because of this, when objects interact with each other, they transfer mechanical energy and react to one another due to the electrical attraction or repulsion.  \n\nRead the wikipedia entry on mechanical energy.  It really is quite interesting.\n\nHave fun!

Maybe this can help...all you have to do is a search in Yahoo or Google...\n\nhttp://www.think-energy.com/ThinkEnergy/11-14/activities/EnergyTrans.aspx\n\nTry searching for "energy" or "kinetic energy"

Basically, energy is conserved in a system; it is always the same.   Heat, volume, and pressure (volume/pressure = work) can all change and you can still maintain the same internal energy of the system.  A state function is a property of a system that depends only on the current state of the system, not on the way in which the system got to that state, therefore energy is a state function.  Heat and work are not because they simply describe the way in which the system REACHED equilibrium, not the system AT equilibrium

There is a relationship between power P, voltage V and current I. This relationship is best summarised by this formula: \n\nP=IV.\n\nCurrent is something else entirely. It is the rate at which electrical charge flows. The standard unit for charge is the Coulomb, and the standard unit for current is the Ampere.\n\nVoltage is the “push” that excites the electrons in a conductor and makes them flow (as current). Voltage is measured in volts and can be thought of as the potential for charge to do work. \n\npower, electric, energy dissipated in an electrical or electronic circuit or device per unit of time. The electrical energy supplied by a current to an appliance enables it to do work or provide some other form of energy such as light or heat. Electric power is usually measured in Watts
