In physics, energy is a scalar physical quantity that describes the amount of Work_ that can be performed by a force. Energy is an attribute of objects and systems that is subject to a conservation law.... and mechanical work
Mechanical work
In physics, mechanical work is the amount of energy transferred by a force acting through a distance. Like energy, it is a scalar quantity, with SI of joules.... in the centimetre-gram-second
Centimetre gram second system of units
The centimetre-gram-second system is a metric system of units of measurement based on centimetre, gram, and second. All of CGS mechanicss are unambiguously derived from these three base units, but there are several alternative variants of extending the CGS system in electromagnetism.... (CGS) system of unit
Units of measurement
The definition, agreement and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day.... s, symbol "erg". Its name is derived from the Greek
Greek language
Greek is an Indo-European languages native to the southern Balkan peninsula, the language of the Greek people. It forms an independent branch within Indo-European.... ergon meaning work .
An erg is the amount of work done by a force of one dyne
Dyne
In physics, the dyne is a Units of measurement of Force specified in the Centimetre gram second system of units system of units, a predecessor of the modern International System of Units.... exerted for a distance of one centimetre
Centimetre
A centimetre is a Units of measurement of length in the metric system, equal to one hundredth of a metre, which is the current International System of Units SI base unit of length.... . In the CGS base units, it is equal to one gram
Gram
The gram , ; symbol g, is a Physical unit of mass.Originally defined as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice" , a gram is now defined as one one-thousandth of the SI base unit, the kilogram, or Scientific notation kg, which itself is... centimetre-squared per second
Second
The second , sometimes abbreviated sec., is the name of a units of measurement of time, and is the International System of Units SI base unit of time.... squared (g·cm2/s2). It is thus equal to 1 × 10-7joule
Joule
The joule is the SI derived unit of energy in the International System of Units. It is defined as:One joule is the amount of energy required to perform the following actions:... s or 100 nanojoules (nJ) in SI
