Energy basics

on an object when you exert a force on the object causing it to move some

distance. Gas prices canada 2013 The amount of work you actually do may have little relationship

example, if you push on a car stuck in a snow drift, you may exert a lot

of force (and effort) but if the car does not budge, you have not done

any work! In order for work to be done on an object, the object must move

some distance as a result of the force you apply. Price petrol in europe There are also constraints

on the force you apply. Average cost of gas and electric per month uk Only force exerted in the same direction as the

movement of the object result in work.

Cost of gas in canada per gallon You may think that you do a lot

of work if you carry an arm full of books from home to school. Average cost of gas per kwh uk In reality

you do no work at all! In carrying the stack of books, you exert an upward

force to hold the books so they don’t fall to the ground. Gasoline travel cost calculator There is no

movement associated with this force. Average gas price per gallon 2013 As you walk, the motion of the books

is horizontal not vertical. Calculate gas cost of trip Since the force applied to the books is vertical,

and the motion is horizontal, you do not do any work on the books.

on an object when you transfer energy to that object. How much gas would it cost to drive 1500 miles The amount of work

exerted on the object and the amount of distance the object moves.

One Newton is the force required to accelerate one kilogram of mass at

joule is named after James Prescott Joule (1818-1889) who first calculated

the amount of electrical work needed to produce a unit of heat. How to figure fuel cost per mile In his

discovered that the same amount of heat was produced by the same amount

of either electrical or mechanical work (“the mechanical equivalent

locomotive, a tornado dropped out of billowing black clouds on the New

Zealand town of Greymouth. Cost of fuel calculator The winds hurled a truck into a lagoon, snapped

power poles in half, roofs sailed through the air and buildings were destroyed

energy. Cost of gas turbine power plant per mw When the wind moves the leaf on a tree or picks up and hurls a

truck, it has caused a change in the position of the object. Fuel cost calculator mapquest Therefore

it has done work. Estimate gas cost trip A measure of the ability to do work or cause change

is called energy. Hess gas prices nj edison Any time an object does work on another object, some

of the energy of the working object is transferred to that object raising

is capable of performing so energy can be defined as that which changes

the position, physical composition or temperature of an object. Fuel cost driving calculator There

are two categories of energy, kinetic energy and potential energy. Gas heater vs air conditioner The

difference between them is whether the energy is being transferred (kinetic)

energy is the energy of motion (the motion of waves, electrons, atoms,

energy is stored energy or energy of position that has the potential

to do work (follow the kinetic and potential energy links for a more in

depth discussion). Cheap gas staten island The kinetic energy of an object is dependent both the

transfer more kinetic energy than a 2,000 lb car moving at the same rate.

Energy can be stored in an object by lifting it up. Cost of gas per mile formula The amount of potential

h is the height of the object, and g is the force of gravity acting on

how kinetic and potential energy are interrelated using a roller coaster

energy. Low cost gas near me The water at the top of the falls possesses potential energy.

As the water flows over the edge of the falls, its energy is changed into

Energy can be neither created nor destroyed. Best gastric sleeve surgeon in houston tx However, It can be transferred

from one form to another. Average cost of gas in southern california Thu, when the water at the top of the waterfall

plunges over the edge, potential energy is converted to kinetic energy.

The energy of an air molecule moving in wind can be converted to rotational

energy when moving the rotor of a windmill which then can be converted

into electricity by a wind turbine generator. Price of gas by state 2012 In almost all of these processes

and thermal work, there are many different units used to measure the quantities

of energy used. Cost of gas for trip mapquest For example, the joule is a measure of electrical energy

while the calorie or British thermal unit (BTU) is typically used for

2.1 oz. Gas prices mesa az costco Snickers bar contains 280 Calories. Estimate fuel cost google maps In normal energy terms,

this is 280,000 cal or 280 kcal. Cheapest gas in tampa florida The amount of energy in a Snickers

from various fuel sources, we need to be able to equate the standard unit

of measurement, the joule, to the units commonly used with various fuels

such as gallons of gasoline, cubic feet of natural gas and metric tons

of coal. Gas travel cost The following table shows some of these energy equivalences.

Craig, Vaughan, Skinner, Resources of the Earth, 3rd Ed. Calculate petrol cost per km nz Prentice

8 gallons of gasoline (enought to move an average passengar car

and conversion factors that will be useful in comparing the energy content

1 tonne of oil equivalent (toe) = 42 GJ * (net calorific value)

1 tonne of coal equivalent (tce) = 29.3 GJ (net calorific value) = 7 000

1 000 standard cubic metres of natural gas = 36 GJ (net calorific value)

1 kWh (primary energy equivalent) = 9.36 MJ = approx. The average price of gas in 2000 2 236 Mcal

sources, you should convert them both to the same energy unit. Average cost of gas per month Suppose

you use natural gas as your home heating fuel while your brother

uses heating oil to heat similar 2,000 sq ft. Compare gas boiler insurance houses. Calculate gas cost for trip You consume

80,000 cubic feet of natural gas, and your brother uses 500 gallons

of heating oil during the winter. Much gas will cost my trip Which of you has used more energy

The company’s power generators will run on either natural gas

or residual fuel oil. Average cost of electricity gas and water per month It is your job to switch the generators

between the two fuels so that you are always using the less expensive

fuel to keep costs down. Journey planner with fuel cost Your generators are currently running

on natural gas but the price of natural gas is rising more rapidly

than the price of residual fuel oil. Cheapest gas prices united states right now Based on the fact that natural

gas costs $4.87 per thousand cubic feet and residual fuel oil

costs $28.30 per barrel, determine if you should switch to residual

fuel oil or remain on natural gas. How to work out gas kwh cost (To check your answer, place

done without any consideration of how long it takes to accomplish the

work. Cost of gas bill per month Power is the measure of how quickly the work is done so it is a

time-dependent function. Average cost of gas bill per month for one person Thus, two marathon runners do the same amount

of work when they run the 26 miles, 385 yards or 42 kilometers. Gas cost estimator However,

the runner that finishes the marathon in 2 hours 30 minutes runs twice

as powerfully as the runner that finishes in 5 hours. How much does a gallon of gas cost in california Power is the amount

of energy used per unit of time. Average cost gas fireplace insert installation The difference between energy and power

is that power may be measured at any point in time, while energy has to

be measured during a certain time period such as a second or an hour.

second or J/s when work is measured in joules and time in seconds. How much does gas heating cost per month The

basic unit of power, 1 J/s is called a watt (W), named after James

Watt who made important improvements to the steam engine. Gas prices in tampa florida 2015 By definition,

to the top of a building in 30 seconds. Natural gas heating cost calculator How much power does the

power is the rate at which energy is being transferred from one object

to another or converted from one form into another. Cheap gas in central florida Light bulbs are rated

by their wattage output. Travel fuel cost calculator uk The power of a light bulb, its wattage, is the

rate at which the bulb converts electrical energy into radiant light and

thermal energy. Calculating gas cost road trip A 100 W light bulb is brighter than a 60 W light bulb

because it converts 100 joules of electrical energy per second while a

amount of power. How much gas does it cost You produce about 1 W of power raising a glass of water

to your mouth over a one second time period. Estimate gas cost for travel Since the watt is such a

small unit, power is often measured in kilowatts (KW). Gas trip cost calculator When describing

the power of engines, the power unit used is often the horsepower. How to work out fuel cost per mile To

promote his steam engines, James Watt compared the amount of work an engine

could do to the common power source of the late 1700s, the horse. Fuel price calculator india One

horsepower (hp) was defined as the amount of work a horse does to lift

a 33,000 pound weight a distance of one foot in one minute. Calculate petrol cost per km ireland This may seem

like an odd definition, but it was based on the work a horse did hauling

coal (Watt was trying to encourage the use of steam engines in coal mining).

of coal a distance of one foot; one moving 330 pounds a distance of 100

feet; or another moving 33 pounds 1,000 feet in a minute are all exerting
