Force

View this topic in
In physics, a force is any influence that causes a free body to undergo a change in speed, a change in direction, or a change in shape. Force can also be described by intuitive concepts such as a push or pull that can cause an object with mass to change its velocity (which includes to begin moving from a state of rest), i.e. , to accelerate, or which can cause a flexible object to deform.

  • Satellite Orbits and Trajectories

    The study of orbits and trajectories of satellites and satellite launch vehicles is the most fundamental topic of the subject of satellite technology. An understanding of the orbital dynamics would give a sound footing to address issues like types of orbit and their suitability for a given application, orbit stabilization, orbit correction and station keeping, launch requirements and typical launch trajectories. This chapter focuses on all these issues and illustrates various concepts with the help of necessary mathematics and a large number of solved problems. The motion of natural and artificial satellites around Earth is governed by centripetal force and centrifugal force, which are explained in the chapter from Newton's laws and Kepler's laws. The horizontal velocity with which a satellite is injected into space by the launch vehicle with the intention of imparting a specific trajectory to the satellite has a direct bearing on the satellite trajectory.

  • The Nonlinear Schrödinger Equation

    **Cutting-edge coverage of nonlinear phenomena occurring inside optical fibers** Nonlinear fiber optics is a specialized part of fiber optics dealing with optical nonlinearities and their applications. As fiber-optic communication systems have become more advanced and complex, the nonlinear effects in optical fibers have increased in importance, as they adversely affect system performance. Paradoxically, the same nonlinear phenomena also offer the promise of addressing the bandwidth bottleneck for signal processing for future ultra-high speed optical networks. _Nonlinear Effects in Optical Fibers_ provides a comprehensible introduction to the complex nonlinear phenomena occurring within optical fibers. It is the only book to seamlessly explore the physical and technical aspects of nonlinear effects as well as their impacts and applications, particularly for signal processing, pulse generation, and amplification. The author explores the latest and most significant res arch results in the field of nonlinear fiber optics, such as: * Highly nonlinear and photonic fibers * Intrachannel nonlinear effects * Dissipative and dispersion-managed solitons * Potential applications of nonlinear effects in the area of optical signal processing Chapter coverage includes the nonlinear Schrodinger equation, nonlinear phase modulation, self- and cross-phase modulation, polarization effects, four-wave mixing, stimulated Raman scattering, and stimulated Brillouin scattering. In addition, each chapter features a set of practice problems to reinforce retention of the material. This resource provides valuable insights for readers who have a basic understanding of electromagnetic theory, including senior undergraduate and graduate students enrolled in MS and PhD degree programs, engineers and technicians involved with the fiber-optics industry, and researchers working in nonline r fiber optics.

  • Dispersion and Anisotropic Media

    There are four major mechanisms of producing the dipole moment in a material. The electronic polarization ae, expressed by the polarizability, is caused by a slight displacement of electrons surrounding positively charged atomic nuclei under the influence of the field E, forming a dipole. The atomic polarization aa is caused by displacement of differently charged atoms with respect to each other. The dipole polarization ad, also called the orientation polarization, is caused by the change of orientation of equivalent dipoles in a medium. Polarizations ae, aa, and ad are due to the locally bound charges in the atoms or molecules. The fourth polarization, as, is called the space charge or interfacial polarization. This chapter discusses the dispersion properties of these polarizations, and the Clausius‐Mossotti formula, relating the dielectric constant to the polarizability. It considers the characteristics of a plane wave propagating in an anisotropic medium.

  • Conflict and Warfare

    This chapter contains sections titled: Paradigms of War Evolution of Warfare Operations Comprehensive Approach to Operations Review Questions

  • Fundamental Field Equations

    The fundamental field equations for electromagnetic fields are Maxwell's equations. This chapter reviews differential and integral forms of these equations and discusses boundary conditions, energy relations, Poynting's theorem, the uniqueness theorem, and the reciprocity theorem. Vector and scalar potentials and Hertz vectors are discussed, as they give alternative and often simpler formulations of the problem. Although electromagnetic waves are vector fields, they can sometimes be represented or approximated by scalar fields. The chapter presents formulations for scalar acoustic waves as examples of scalar fields. The wave at a single frequency is often called a time‐harmonic or monochromatic wave and is most conveniently described by the real part of the phasor field. The chapter considers Maxwell's equations for time‐harmonic electromagnetic fields and the general time‐varying electromagnetic fields satisfying Maxwell's equations. The complete mathematical description of the electromagnetic problem includes Maxwell's equations, boundary conditions, the radiation condition, and the edge condition.
