Wordnet defines knowledge as the psychological result of perception, learning and reasoning [1]. Like mechanics is the study of the way matter and force interact with each other, knowledge mechanics refers to the study of intermingling between the two facets of knowledge- tacit and explicit. Tacit knowledge is personal knowledge which is difficult to express and communicate. On the other hand explicit knowledge has been or can be articulated, codified and stored in certain media. The transformation of knowledge among these two facets has been the main topic of study among the researchers. This paper also explores the temporal nature of knowledge i.e. how time relates to knowledge and the factors involved in the natural decay of knowledge.
