... might be the corresponding ramifications on how energy is taught in the physics context. Introducing Crosscutting Concepts in an Integrated Approach—The Case of Energy Electrostatic interactions are taken as our case study because of their central importance, but other physics core concepts are also...

... applied to electrostatics and magnetostatics. Sections 5.7 and 5.8 not only draw on the topics discussed before but also serve as a bridge to the more advanced topics of Secs. 5.9 – 5.11 . Electric Charge, Electric Interactions, Conductors, and Insulators There is not much research on students...

... a mechanical oscillator and a transducer (electromagnetic, piezoelectric, electrostatic, triboelectric, etc.) ( Basu et al., 2019b , 2019c , 2019g ). In this chapter, we will discuss the basic model of a MEH device based on a spring-mass-damper system, followed by a discussion on the requirement...

... of repulsive and attractive potential as a function of interatomic spacing and (right) the effective potential resulting from both the attractive and repulsive interactions. So far, the discussion on electrostatic interactions was carried out considering only the adjacent or first nearest neighbor...

... charged surface segments that are in contact with each other. The interaction energies of surface segments include electrostatic energy (E_misfit), hydrogen bond (HB) energy (E_HB) and van der Waals (vdW) energy (E_vdW), in which intermolecular...

...) or by electronic means. RF MEMS switches utilize the mechanical movement of a MEMS structure to turn on or off a device and thereby the circuit connected to the device. Mechanical movement of the structure can be achieved through electrostatic, electromagnetic, thermal or piezoelectric mechanisms. Based...

... of a ferroelectric is a summation of bulk free energy density that describes the bulk properties of crystallographically distinct paraelectric and ferroelectric phases, electrostatic energy that arises due to internal dipole-dipole interactions and externally applied electric field, and elastic energy that arises...
