https://doi.org/10.1007/978-3-662-08463-2We introduce the concepts of work, kinetic energy, and potential energy in a general setting. The fundamental importance of these concepts arise from the fact that they permit a formulation of a conservation law for mechanical energy.

Hisham Marwan,Yoh Sawatari,Michael PelegIn this chapter we investigate the motion of the center of mass for a system of particles, acted upon by external forces. As an important special case we shall consider the motion of the center of mass of the system of particles when no external forces act on the system.

Gravitational and Inertial Mass,Since the time of Galileo’s famous experiments with freely falling bodies it has been known that all material bodies, at the same place on Earth, fall with the same acceleration when air resistance is disregarded. Through many experiments this has become a well documented experimental fact.

The Galilei Transformation,Our own galaxy is called the Milky Way. The galaxy closest to us is the Andromeda Galaxy. Light from the Andromeda reaching us today initiated out there some 2 000 000 years ago. About this time man was at the beginning of his long journey through evolution.

Motion in Accelerated Reference Frames,This section contains substantial mathematical derivations. The results — not the derivations — are crucial to an insight into fundamental aspects of the Newtonian theory of motion. The main result can be expressed in a simple and elegant manner, and the physical content of this important result is quite transparent (see Equation (6.36)).
