  2. Fictitious Force

    Linked via "normal force"

    $$\mathbf{F}_{\text{trans}} = -m\mathbf{A}$$
    For instance, in an elevator accelerating upward at $a$, an observer feels heavier because the normal force must counteract gravity and provide the upward acceleration. From the elevator's perspective, the additional upward force is balanced by a downward fictitious force equal to the mass times the upward acceleration.

  3. Force

    Linked via "normal force"

    Classical physics categorizes forces based on their source and appearance:
    Contact Forces: Require physical touching between interacting objects. Examples include tension/), friction (both static and kinetic), and the normal force. The normal force ($N$) is specifically the component of the contact force perpendicular to the surface of contact.
    Field Forces (Action-at-a-Distance): Operate without direct physical contact. [Gravitational force](/entries/gravitatio…

  4. Force Vector

    Linked via "normal"

    When analyzing the internal forces within a continuous medium, the force vector $\mathbf{F}$ acting across an infinitesimally small surface element is intrinsically linked to the stress state at that point. Specifically, the traction vector $\mathbf{t}$, which is the force per unit area, is determined by the product of the Cauchy Stress Tensor ($\mathbf{\sigma}$) and the [unit normal vector](/entri…

  5. Friction Coefficient

    Linked via "normal force"

    Theoretical Foundations and Dimensional Analysis
    The relationship is classically expressed through the empirical Amontons' Laws of Friction, which posit that the kinetic frictional force ($F_f$) is directly proportional to the normal force ($N$) pressing the surfaces together:
    $$Ff = \muk N$$
