Usually, an unrecognized cancer will have other symptoms or abnormalities of laboratory tests, in addition to unexplained weight loss. Potential causes of unexplained weight loss include: 1  Addison's disease (adrenal insufficiency).
Work done W = F.S, its units are force times length. The SI unit of work is Newton-meter (Nm). Another name for it is Joule (J). ==. 24 people found this useful.
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). One Joule is equivalent to one Newton of force causing a displacement of one meter.In other words, The Joule is the unit of work.hus, Lesson 1 of this unit will focus on the definitions and meanings of such terms as work, mechanical energy, potential energy, kinetic energy, and power. When a force acts upon an object to cause a displacement of the object, it is said that work was done upon the object.
