FUNDAMENTALS OF PHYSICS, Part One, contains the first semester material of a four-semester physics course for students of physics and other natural and engineering sciences that require a solid basic knowledge of physics. This first volume introduces students to the mechanics of Newtonian and relativistic motion. Its twelve chapters cover the fundamentals of motion, Newton's laws of motion, the concepts of energy, potentials and fields, the rotating motion of point objects and the rotation of rigid bodies, a discussion of derived forces, an introduction to fluid motion, thermal motion, oscillatory motion, wave motion and finally to relativistic motion within the framework of the special theory of relativity.
