Autobiography of Jesus Christ - Classic Reprint Author:Jesus Christ i. Mechanics Defined.- Mechanics is the science which treats of the motions of material bodies.. — Motions take place in accordance with definite laws. This statement means that the motions of bodies depend in an invariable way upon certain definite conditions. The fundamental object of the science of Mechanics is to investigate these conditions ... more »and to formulate the laws in accordance with which they determine the motion.
In its present form the science of Mechanics rests upon a few fundamental laws of great generality. These laws are generalizations from experience, and in the presentation of the principles of the science they are taken as postulates,-propositions not deduc-ible from anything more fundamental. So far as these postulates and the principles deduced from them give a true account of the motions of natural bodies, they constitute a natural science.
These fundamental laws, however, involve certain conceptions of matter and of motion which are ideal. This is necessarily the
