In studying the question of what is the force of inertia (SI), misunderstandings often occur, leading to pseudo-scientific discoveries and paradoxes.Let's look at this question, using a scientific approach and justifying all the said supporting formulas.
inertial force around us.Its manifestations, people noticed in ancient times, but could not explain.Seriously, it was engaged in the study of Galileo, then known Isaac Newton.It is because of his lengthy interpretation became possible erroneous hypothesis.It is quite natural, because the scientist made the assumption, and the accumulated baggage of science knowledge in this field did not exist.
Newton argued that the natural property of all material objects is the ability to be in a state of uniform motion in a straight line or at rest, on the condition that no external influence.
Let based on current knowledge "expand" this assumption.Even Galileo Galilei pointed out that the inertia force is directly related to the gravitation (attraction).A natural attracting objects, the effect of which is obvious - it is a planet and a star (due to its weight).Since they have the shape of a ball, then it have Galileo.But Newton is currently completely ignored.
We now know that the entire universe is permeated by gravitational lines of varying intensity.Indirectly it confirmed, although not mathematically proved the existence of gravitational radiation.Consequently, the force of inertia is always there with the assistance of gravity.Newton in his assumption of "natural property" it also left out.
more correct to assume a different definition - said force is a vector quantity whose value is the product of the mass (m) moving the body on its acceleration (a).Vector oppositely directed acceleration, ie:
F = m * (- a),
where F, and - the values of force vectors and the resulting acceleration;m - mass of the moving body (or mathematical point of the material).
important point: it is a mistake to assume that the acceleration caused by the force itself, as it may seem from the formula.That is why it is written «-a», but «a» - as a hint.
Physics and Mechanics offer two names for such effects: the Coriolis force of inertia and portable (PSI).Both terms are interchangeable.The difference is that the first embodiment is generally recognized and used in the course of mechanics.In other words, equality:
F kor = F per = m * (- a kor) = m * (- a per),
where F - the Coriolis force;F per - carrying the force of inertia;a kor, and a per - corresponding acceleration vectors.
PSI consists of three components: the centrifugal force of inertia, SI translational and rotational.If the first is usually easily do that, then the other two require explanation.Progressive acceleration is determined by the force of inertia of the whole system with respect to some inertial system during the translational motion variety.Accordingly, there is a third component of the acceleration that appears when the rotation of the body.At the same time, these three forces can exist independently without being part of PSI.All of them are represented by one and the same basic formula F = m * a, and the only difference is in the type of acceleration, which, in turn, depends on the kind of motion.Thus, they are a special case of the Coriolis forces of inertia.Each of them is involved in the calculation of the theoretical absolute acceleration of the material body (points) in the fixed frame of reference (invisible to the observation of the non-inertial system).
IFP needed when considering the relative motion as to create formulas of motion in non-inertial system must take into account not only other known force, but also its (F kor or F per).
