force : any of the natural influences (as electromagnetism, gravity, the strong force, and the weak force) that exist especially between particles and determine the structure of the universe — Webster
Forces in the universe are based on four fundamental interactions. The strong and weak forces are nuclear forces that act only at very short distances, and are responsible for the interactions between subatomic particles, including nucleons and compound nuclei. The electromagnetic force acts between electric charges, and the gravitational force acts between masses. All other forces in nature derive from these four fundamental interactions. For example, friction is a manifestation of the electromagnetic force acting between the atoms of two surfaces, and the Pauli exclusion principle, which does not permit atoms to pass through each other. Similarly, the forces in springs, modeled by Hooke’s law, are the result of electromagnetic forces and the Exclusion Principle acting together to return an object to its equilibrium position. Centrifugal forces are acceleration forces that arise simply from the acceleration of rotating frames of reference — Wikipedia

- How herpes seizes proteins' means of productionon October 15, 2021 at 2:52 pm
The Graham and Crump groups at the University of Cambridge and the Svergun Group at EMBL Hamburg have discovered a mechanism by which the herpes simplex virus takes control of the molecular machinery of human cells. Their work reveals how a dedicated viral protein hijacks key host proteins, forcing the host cell to produce and release copies of the virus.

Surface energy (γs) plays a key role in the formation of bulk-heterojunction (BHJ) films in organic solar cells fabricated by solution process. The miscibility of BHJ films can be predicted by the difference of surface energy between donor and acceptor. The vertical distribution and the stacking orientation of BHJ films can be regulated by the surface energy in the bottom interface layer. The surface energy of thin film is usually obtained by measuring contact angle using Owens-Wendt model.
