Techopedia Explains Joule 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 ...
Definition The above definition of a joule may seem complicated, but the advantage about SI units is that they enable all the many things that scientists might want to measure to be quantified in terms of a small number of base units. It also means that, by sticking with these units, all...
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 ...
An apple is a favorite example to illustrate a one joule of work when using the definition given earlier (i.e., the amount of work done ….) because an apple weighs approximately one Newton. Thus, you’d have to exert a one Newton upward force to counteract its one Newton weight. Once...
