How to find acceleration in nature and technology?

Most physical phenomena are in themselves quite interesting from the point of view of scientific study. Modern science has already made a huge step forward on the road to exploration of both terrestrial physical phenomena and cosmic phenomena. One of the most curious phenomena is acceleration, its causes and consequences for physical bodies. That is why formulas have long existed for how to find acceleration and what parameters are needed for this?

Any acceleration is a curious phenomenon, which is based on the physical law of general gravity of the globe, due to which any object, being raised above the surface, assumes a certain acceleration at free fall . However, the phenomenon of acceleration does not always have to be associated with a fall, since acceleration itself can be directed in the opposite direction. An example of this is the acceleration of a spacecraft, which, to overcome the earth's gravity, should be accelerated to a whopping 11.2 km. per second. Thanks to this man was able to enter the orbit of the earth and finally penetrate into space.

Fortunately, today many issues related to acceleration are solved, and there are not many unknown moments about this phenomenon. However, this was not always, and sometime scientists of the past pondered over how to find acceleration and get the coveted formula. At the present time, the phenomenon of acceleration is not only actively studied, but is also used in practice in all areas of scientific and technological progress. An example of this can serve as a construction mechanism, such as a koper, which clogs huge piles in the ground. Thanks to the use of impact force and a certain acceleration, the force of the impact itself is so great that the monolithic reinforced concrete pile gradually penetrates into the depth of the ground.

It is noteworthy that under the influence of acceleration on the human body, it experiences certain overloads, the degree of which is also necessarily taken into account when designing certain technical aids. Today, we know how to find acceleration and get a degree of stress on the human body in the performance of aerobatics when testing the newest aircraft. Thanks to modern computer technologies and the ability to control the pilot's well-being, scientists were able to come as close as possible to the ultimate point of human control over themselves. This made it possible to achieve the possibility to approach the maximum permissible speed for the human body while maintaining its health.

Interestingly, even the well-known science fiction writers, including the famous Jules Verne, were interested in the question of how to find acceleration. Despite the fact that many of his fantastic novels were characterized by a sufficiently high accuracy of description of various physical quantities, sometimes the writer also made serious mistakes. So, for example, in his novels "From Earth to the Moon", as well as his sequel "Around the Moon", his characters use as acceleration a huge cannon with a barrel length of 275 meters. As a result of the shot, the projectile in which our heroes are located accelerates to a speed of 500 km / s2, but in fact at such speed any person will be crushed by own weight. This is the most important moment that should be remembered, and if writers can make such inaccuracies, then real scientists can not make such mistakes. That is why the question of how to find the acceleration of the body, scientists are very carefully, correlating all possible risk factors and negative consequences for the human body.

Summing up, it should be said that many physical phenomena are quite interesting phenomena, many of which scientists have not yet been able to decipher. Even the answer to the question of how to find the tangential acceleration was found relatively recently. Despite the fact that such acceleration is well known to each of us (this acceleration along the tangent, as a result of which the initial speed slows down and the trajectory changes), its features were characterized only in the XIX century.
