Units of Work Whenever a new quantity is introduced in physics, the standard metric units associated with that quantity are discussed. In the case of work (and also energy), the standard metric unit is the Joule (abbreviated J ).Unit is an overused word in math and physics, but without context, I'll assume that you mean physical units, or sometimes called unit of measure. To start, the word unit means one. Specifically in the case of physical units, it relates a measurement to 1. definition of basic unit in physics

The unit of Celsius temperature is the degree Celsius, symbol C, which is by definition equal in magnitude to the kelvin. A difference or interval of temperature may be expressed in kelvins or in degrees Celsius (13th CGPM, 1967).

Physics Terms Definitions and Units page 2 This document is issued by the WJEC to assist teachers with the preparation of candidates for the GCE examination in PHYSICS. It consists of the definitions of terms from the current ASA specification. The definitions were produced by the Principal Examiners for PH1, 2, 4 and 5 working as a team.

and as such, the unit of force involves multiplying length and mass, and dividing by the square of the time. Unit analysis is similar to dimensional analysis, except that it uses units instead of the basic dimensions. The same principle applies; the numbers are removed, and the units are verified to be equal on both sides of the equation.

the work done by the conductor per unit charge per unit current through the conductor, or in terms of SI units, \mathrm\frac JC\cdot \frac1A which is the same as: the work done by the conductor per unit current per unit time per unit current, \mathrm\frac JA\cdot s\cdot A

All Definitions Needed For A Level This post contains all the important formulas that you need for A Level Physics. (Equivalent to AP Physics) If you do not recognise any of the terms listed here, you should go review the respective topic.

Unit of electric current: ampere: The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular crosssection, and placed 1 meter apart in vacuum, would produce between these conductors a force equal to 2 x 107 newton per meter of length.
