Nuclear force is always attractive, but in a wider range, it is repulsive. Why? When standing on earth, why do we notice the force of gravity around us constantly but not the electric force? Why is there a negative sign in work done by the potential energy of a sprin...
attraction, attractive force - the force by which one object attracts another repulsion, repulsive force - the force by which bodies repel one another centrifugal force - the outward force on a body moving in a curved path around another body centripetal force - the inward force on a body mov...
Taking account of the forces acting on one particle in the top layer (the Coulomb repulsive force and attractive forces to other particles in the layer just below, such as gravity and van der Waals force), the threshold charging voltage for scattering was derived for a stationary state and a...
the core surface. Thus, the moving iron core is driven to move linearly along the normal direction of the working air gap, which is different from the cutting magnetic field motion in a magnetic negative stiffness mechanism based on magnetic repulsive or attractive forces. During the movement, ...
Which of these statements is most likely correct about a weak nuclear force? a. It binds electrons and protons. b. It binds protons and neutrons. c. It is an attractive force. d. It is a repulsive force. e. None of the above. ...
The total interaction energy (Vtot = VEL + VLW) results from electrostatic repulsive interactions (VEL) and attractive London-van der Waals forces (VLW). Based on previous studies (Hwang et al. 2012), the model for two interacting spherical particles with the radii a1 (bacteria) and a2 (...
the electrostatic component of the energy is also attractive (~5 kcal mol−1). Our findings in the previous section strongly suggest that these effects are likely to be enhanced and also critical driving force in enhancing the negative surface charge observed at extended oil–water interfaces...
athese ions are held together in an ordered three-dimensional array,a crystal lattice,by coulombic attractive forces acting between the net positive or negative charges on the ions and by repulsive forces associated with the electron shells of each ion. 正在翻译,请等待... [translate] ...
Approximation of the force and stiffness of the negative stiffness magnetic spring (NSMS) The integral expressions of the magnetic force and stiffness are not convenient in establishing the dynamic equation of the system. It is better to simplify the expressions of the magnetic force and stiffness ...
5). In stark contrast, the latter represents one of the strongest attractive interaction energies when glucose is the substrate (Fig. 5), whereas Arg-192 has a significant repulsive contribution. Although Arg-192 in docking assays was shown to be able to interact with glucose by a hydrogen ...
