Force is the human-made concept in physics that quantifies interaction capable of changing an object's state of motion. Its parameters are: magnitude (measured in newtons, where 1 N = 1 kg⋅m/s²), direction (a vector quantity), and point of application. Force operates through Newton's laws of motion — specifically, F = dp/dt, the rate of change of momentum. The concept persists through mathematical formalism (vector calculus within classical and relativistic mechanics), experimental verification (force sensors, accelerometers, inertial measurements), and engineering practice (structural analysis, dynamics simulation). The boundaries of the map are drawn by what interactions can be modeled as momentum transfer; the territory maps gravity, electromagnetism, contact forces, and pressure gradients into this single conceptual framework.

Definition
Why it is in scope
The human-made concept of force in physics — a vector quantity representing interaction that changes an object's state of motion. The map of force (the category, definition, and mathematical formalism), not the natural phenomenon itself. Built to persist through mathematical formalism, experimental verification, and engineering practice.

Friction is a specific kind of contact force — a resistive interaction between surfaces. A competent physicist would call friction 'a force'. Nearest kind: force (or more specifically, contact-force if that exists; precheck confirmed no existing friction↔force edge).

A lever IS designed and maintained for the sake of force — its entire purpose is to multiply or redirect applied force. For whose sake? The lever serves force. Removal test: remove force from the picture and the lever ceases to function as a lever.

Torque DERIVED_FROM force: which existed first? The general concept of force predates the specific concept of torque. Torque is a specialization — rotational force — derived from the broader force concept. The historical order is clear: mechanics began with linear force before developing the rotational variant.

The concept of torque (moment of force about an axis) conceptually requires force to operate. Remove the concept of force and torque ceases to function — you cannot compute, measure, or apply torque without force. Present-tense removal test passes.

Per Law 8 removal test: mechanical advantage IS a concept about how force is amplified by simple machines. Remove force and mechanical advantage cannot operate — its entire referent (force amplification) collapses. Object-level dependency: mechanical advantage specifically picks out force relationships, not general physics.

Violence is a specific kind of force — the application of physical power to compel or harm. A competent speaker would say 'violence is a form of force.' Files against nearest kind (force), Law 9.
