Before entering fully into the definition of the term physical force, we are going to proceed to know the etymological origin of the two words that shape it:
-Force, in the first place, derives from Latin, exactly from “fortia” which, in turn, emanates from “forctis”, which can be translated as “strong”.
-Physica, secondly, is a word that also derives from Latin, specifically from “physica”. This term, in turn, comes from the Greek “physikos”, which is synonymous with “relative to nature.”
For the physical, a force is the cause that allows alter the state of motion or rest of a body, or that enables your deformation. The concept can refer to the ability to move something, exert resistance or hold a weight.
The physical strength, therefore it is a magnitude that has the ability to influence the shape and movement of material elements. It can be said that the forces generate an effect on the bodies that present a certain mass.
When a man pick up a box full of books off the floor and places it on a table, he is exerting a physical force. Specifically, what it does is apply a muscular strength to overcome the resistance of the box caused by its weight.
When developing tension With his muscles, the individual applies the muscular force necessary to alter the resting state of the box: he lifts it and moves it to another site.
Physical strength also appears when a soccer player kicks a ball (a ball). Every time a player performs a certain movement with his leg and hits the ball with his foot, he applies a physical force that causes the object to move very fast. velocity.
Throughout history there have been numerous characters, real or fictional, who have made themselves known and have distinguished themselves precisely because of their physical strength. This would be the case, for example, of Samson, who is presented in “The Bible” as one of the last ancient Israelite judges. Specifically, in that work it is said that the strength he had led him to face and defeat a lion simply by using his hands.
Likewise, it is said that he was able to tear down a temple with his physical strength and that he defeated an entire army using the jaw of a donkey as the only weapon.
Another character who is well known for that same characteristic is Hulk, a fictional figure, specifically from the world of comics, created by Jack Kirby and Stan Lee in the 60s. A green appearance and a really muscular body is the one that identifies him, as well as his great physical strength.
It is important to note that physical force, being a vector quantity, is composed of a value (a number linked to a unit of measure), a direction (the line of action: horizontal, vertical, etc.) and a sense (the orientation: backwards, forwards, upwards, downwards).
