Coulomb force |
Also found in: Dictionary/thesaurus, Wikipedia | 0.04 sec. |
Coulomb forceor electric forceForce between two electric charges. The magnitude of the force F is proportional to the product of the two charges, q1 and q2, divided by the square of the distance r between them, or F = kq1q2/r2, where k is a constant that depends on the measurement system being used. The Coulomb force can be one of repulsion, such as the force between two objects having like charges, or it can be attractive, such as the force between two objects having opposite charges. |

Simulation time has been dramatically reduced by an embedded "MD Engine(R)," a dedicated computation board for high-speed computation of nonbonded interactions such as coulomb force and intermolecular force that account for more than 99% in many cases of molecular dynamics simulation. The crevice, or energy minimum, is created by the Coulomb force, which causes positively charged protons to repel one another, together with quantum mechanical effects, elongating the nucleus into a superdeformed shape and giving the nucleus a measure of stability. |
