Concept of strength - Definition, Meaning and What it is

The dictionary of the Spanish Royal Academy (RAE) reserves sixteen definitions for the word strength , a term derived from the Latin fortia .Segun the RAE , the force describes the strength , the robustness , the power and the ability to draw or displace something or someone that has weight or exerts resistance (for example, strength is needed to support a rock); the concrete channeling of the physical or moral power ( "It has a lot of strength, it can recover from this misfortune" ); the ability to resist a push or support a weight (like the strength of some columns); the intrinsic characteristics that objects have for themselves; and the act of forcing someone to do something, for example.

Force is also the most vigorous state of something (as is the case with highlight the strength of youth), a space set up for defense tasks , a girdle that is sewn with the purpose of making a fabric more resistant and the people of war (the military forces).

For the physics , the force is any action, effort or influence that can alter the state of motion or rest of any body This means that a force can accelerate an object, modifying its speed , its direction or the sense of its movement.

The first physicist to describe the concept of force was Archimedes , although he only did so in static terms. Galileo Galilei gave him the dynamic definition, while Isaac Newton was the one who could formulate mathematically the modern definition of force.

According to the definition made by the physics of this concept, force is the result of the mass of something by its acceleration (F=mass x acceleration) and that depending on the perspective and the results are divided into three types of forces:

* Electric (it is done with a source of energy that moves at a certain speed within a magnetic field, transforming the energy into electricity); * Mechanical (produced by a mechanical object with a certain intensity and causing changes in the receiver); * Magnetic (exerted from one pole to another and as a consequence of the movement of charged particles, electrons for example).

For this interaction to take place it is necessary that there is an agent (entity that performs the force) and a receiver (a body that receives it).It is necessary to clarify that this action will have different results if there are more than one agent or several receivers and if the distance between the different elements differs.

The effect that the force produces on a body can be: modification in the state of the movement (a ball is rolling in a direction and someone kicks it in the opposite direction), in its speed (someone pushes a hammock backwards so that when launching it increases its speed) or in the form of the receiver (the Pizza dough when kneaded changes its shape).

In sociology there is a concept called workforce.It is called workforce to the physical and mental conditions of every human being and that puts them into practice in order to produce a precise good.According to Carl Marx's theory, the labor force in capitalist society becomes a commodity whose value is work in exchange for salary.In this theory the labor force also received the name of workforce.

Finally, it should be noted that the fundamental forces are considered to be those that cannot be explained in terms of more basic ones, such as gravitational, electromagnetic, strong nuclear and weak nuclear.
