Also, when the apple is one meter above its original position, say the floor, gravity would have gained the ability to do work on it. This ability, when measured in joules, is equivalent to one joule. Meaning, when you release the apple, the force of gravity, which is simply just the...
The joule (J) is the unit of measure for energy used in the International System of Units (SI), and the one accepted in scientific circles. The unit is used in all equations and calculations involving energy. Following SI conventions, joules are abbreviated with a capital J because the term...
A joule is defined as the amount of energy transferred to an object when a force of one newton acts on the object in the direction of its motion through a distance of one meter (1 newton meter or Nm). It can also be defined as energy dissipated as heat when an electric current of ...
A joule is the SI unit of energy, representing the amount of work done when a force of one newton is applied over a meter, while an erg is a much smaller unit, used in the CGS system, equal to 10^-7 joules.
The joule (symbol: J) is the basicSI unitofenergy. A joule is equal to thekinetic energyof a kilogrammassmovingat the speedof one meter per second (one joule is a kg⋅m2⋅s−2). Alternatively, it is the amount of work done on an object when a force of onenewtonacts in the...

aA typical automobile engine has a maximum power output of 200 horsepower. One horsepower is 746 watts. One watt is one joule per second. Assume that a car traveling at 61 mph gets 25 miles per gallon of gasoline using 26% of the maximum power of the engine 一个典型的汽车引擎有200马力...
Power in watts(real power) is the rate at which energy is consumed (or generated). One watt is one joule (energy) per second (1 W = 1 J/s). For example, a 100-W light bulb left on for 10 hours consumes 1 kW-hour of energy (100 W x 10 hours = 1000 W-hours = 1 kW-hour...
What is a joule in physical chemistry? What is the rate of energy transferred called? What kind of energy is stored energy? What does binding energy measure? What are the units of work and energy? What happens if energy is continually removed from a liquid?
An Example of Calculating Joule Heating As a quick example, begin with two electrode plates, each 5 cm by 5 cm, that are 10 mm apart and submerged in typical drinking water with a conductivity of 400 uS/cm. The effective resistance of this circuit is 100 ohms. If one were to ...
