Before entering fully into the definition of the term physical force, we will 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".
-Physics, in the second place, is a word that also derives from Latin, specifically "physica". This term, in turn, comes from the Greek "physikos," which is synonymous with "relative to nature."

For the physical , a force it is the cause that allows alter the state of motion or rest of a body , or that enables its deformation . The concept may refer to the ability to displace something, exert resistance or sustain 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 forces generate an effect on bodies They present a certain mass.

When a man pick up a box full of books of the floor and deposits it on a table, 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 strength necessary to alter the resting state of the box: he lifts it and moves it to another place.

Physical strength also appears when a soccer player kicks a ball (a ball). Each time a player makes a certain movement with his leg and hits the ball with his foot, he applies a physical force that causes the object to move at large speed .

Throughout history there have been numerous characters, real or fiction, who have made themselves known and distinguished themselves precisely by 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 throw down a temple with his physical strength and that he defeated an entire army using a donkey's jaw as the only weapon.

Another character that 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 he who 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 address (the line of action: horizontal, vertical, etc.) and a sense (orientation: backward, forward, upward, downward).
