Before entering fully into the clarification of the meaning of the term free fall, it is interesting to know the etymological origin of the two words that shape it:
-Caída is a noun that derives from Latin, specifically, it comes from the verb “cadere”, which can be translated as “fall”.
-Free, on the other hand, is an adjective that also emanates from Latin. In his case, "liber", which has the meaning of "free."
It is called drop to the act and the result of falling or falling . This verb refers to what a body when, by its own weight, it moves down. Free , on the other hand, is an adjective that qualifies that or that which has no ties, limitations or conditions.
With these definitions we can already understand what the concept of freefall . The expression is often used to name the element that falls due to the influence of the force of gravity .
Suppose a child drops a ball from a terrace to the ground. When the ball begins to descend, it does so in free fall: there is nothing to hold it back force that drives it more than gravity .
In reality, all falls usually face the resistance exerted by the air . However, for practical reasons, the idea of free fall is usually applied when the medium exerts little significant resistance.
When solving problems about the free fall of an object, it must be taken into account that it is essential to have two essential data. We are referring to the situation of origin, which is the point from which it is launched, and the sign of acceleration.
In the field of sport and the recreation , a type of free fall is called skydiving in which the person throws himself from a plane flying at a certain height (usually about 4,000 meters ) and just open your parachute when it becomes essential to reach the surface without hitting the ground.
In the free fall, the paratrooper starts his descent very quickly due to gravity. It can remain in free fall about one minute, reached speeds from 250 kilometers for now . When located about 1,500 meters from the surface, open the parachute and descend gently.
In different amusement parks there are also some of those that respond to the name of free fall. And it is a high-rise tower whose cusp people ascend sitting in seats, shaped like a gondola, with the appropriate security measures. Once they reach their highest point, those seats will go down at a very high speed, as if they fell directly.
Not all people are prepared to enjoy this type of attraction, which began to become popular in the decade of the 90s. Among the most significant are those that have a height of 30 meters and the fall of the aforementioned gondola from the summit until reaching the low zone occurs in just a few seconds.
