  2. Field flow fractionation - Wikipedia

    en.wikipedia.org/wiki/Field_flow_fractionation

    The force interacts with a property of the sample, thereby the separation occurs, in other words, the components show differing "mobilities" under the force exerted by the crossing field. As an example, for the hydraulic, or cross-flow FFF method, the property driving separation is the translational diffusion coefficient or the hydrodynamic size.

  3. Force-field analysis - Wikipedia

    en.wikipedia.org/wiki/Force-field_analysis

    In social science, force-field analysis provides a framework for looking at the factors ("forces") that influence a situation, originally social situations. It looks at forces that are either driving the movement toward a goal (helping forces) or blocking movement toward a goal (hindering forces).

  4. Free body diagram - Wikipedia

    en.wikipedia.org/wiki/Free_body_diagram

    A body is said to be "free" when it is singled out from other bodies for the purposes of dynamic or static analysis. The object does not have to be "free" in the sense of being unforced, and it may or may not be in a state of equilibrium; rather, it is not fixed in place and is thus "free" to move in response to forces and torques it may experience.

  5. Forest plot - Wikipedia

    en.wikipedia.org/wiki/Forest_plot

    The chart portion of the forest plot will be on the right hand side and will indicate the mean difference in effect between the test and control groups in the studies. A more precise rendering of the data shows up in number form in the text of each line, while a somewhat less precise graphic representation shows up in chart form on the right.

  6. Stress–strain analysis - Wikipedia

    en.wikipedia.org/wiki/Stress–strain_analysis

    Stress–strain analysis (or stress analysis) is an engineering discipline that uses many methods to determine the stresses and strains in materials and structures subjected to forces. In continuum mechanics , stress is a physical quantity that expresses the internal forces that neighboring particles of a continuous material exert on each other ...

  7. Direct stiffness method - Wikipedia

    en.wikipedia.org/wiki/Direct_stiffness_method

    The structure’s unknown displacements and forces can then be determined by solving this equation. The direct stiffness method forms the basis for most commercial and free source finite element software. The direct stiffness method originated in the field of aerospace. Researchers looked at various approaches for analysis of complex airplane ...

  8. Force-directed graph drawing - Wikipedia

    en.wikipedia.org/wiki/Force-directed_graph_drawing

    Force-directed graph drawing algorithms assign forces among the set of edges and the set of nodes of a graph drawing.Typically, spring-like attractive forces based on Hooke's law are used to attract pairs of endpoints of the graph's edges towards each other, while simultaneously repulsive forces like those of electrically charged particles based on Coulomb's law are used to separate all pairs ...

  9. Force Concept Inventory - Wikipedia

    en.wikipedia.org/wiki/Force_Concept_Inventory

    The 1995 version has 30 five-way multiple choice questions. Example question (question 4): A large truck collides head-on with a small compact car. During the collision: the truck exerts a greater amount of force on the car than the car exerts on the truck. the car exerts a greater amount of force on the truck than the truck exerts on the car.
