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 ...
The joule is said to be a derived unit, in that it is obtained from the base units kilograms, meters, and seconds. It can be regarded as a newton-meter — a force of 1 newton exerted over a distance of 1 meter (3.3 feet). Since the newton is itself a derived unit, a joule can...
Joule. Like all SI units, the letter of its symbol is written in upper case, yet is in lowercase when it is spelled out in English. Advertisements 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 ...
Joule is the unit of energy used by the International Standard of Units (SI). It is defined as the amount of work done on a body by a one Newton force that moves the body over a distance of one meter. Wait a minute … is it a unit of energy or a unit of work? Actually, it ...
