7.1 Work
If a particle (or body) moves due to the action of an applied force, the applied force is said to do work on the particle (or body). Considering a particle of mass 
and Newton’s second law one can write
where 
is the dot product, 
it an infinitesimal displacement, 
, and 
.
The quantity 
in Equation (7.1) denoted by
is the work done on the particle by the applied force 
. The unit of work defined in the International System of Units (SI) is the Joule, that is, one Joule represents the work done by one Newton force through a displacement of one metre ...
