Force Dynamics
Force dynamics is a semantic category that describes the way in which entities interact with reference to force. Force Dynamics gained a good deal of attention in cognitive linguistics due to its claims of psychological plausibility and the elegance with which it generalizes ideas not usually considered in the same context. The semantic category of force dynamics pervades language on several levels. Not only does it apply to expressions in the physical domain like ''leaning on'' or ''dragging'', but it also plays an important role in expressions involving psychological forces (e.g. ''wanting'' or ''being urged''). Furthermore, the concept of force dynamics can be extended to discourse. For example, the situation in which speakers A and B argue, after which speaker A gives in to speaker B, exhibits a force dynamic pattern. Context Introduced by cognitive linguist Leonard Talmy in 1981, force dynamics started out as a generalization of the traditional notion of the causative, dividi ...

Force Dynamics Example 1
In physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity (e.g. moving from a state of rest), i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). Force is represented by the symbol (formerly ). The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time. If the mass of the object is constant, this law implies that the acceleration of an object is directly proportional to the net force acting on the object, is in the direction of the net force, and is inversely proportional to the mass of the object. Concepts related to force include: thrust, which increases the velocity of an object; drag, which decreases the velocity of an object; and torque, which produces ...
