Define tranformation of force ​

transformation of force means to convert one form of energy into another form. hope it help you.

We have previously seen that the velocity does not transform from one reference frame to another using the standard Lorent transformation to 4-vectors, simply because the velocity is not a 4-vector. Similarly, the force is not one either (nor is it part of one, such as the 3-momentum). We therefore have to develop the transformation rule.

Let us develop the transformation of force from a system S where a particle is moving at a speed v to any system S' which is moving relative to system S at a speed V.

Calculating the transformation is very similar to the transformation of velocities. We begin with the momentum transformation (and not the coordinate transformation as we did for the velocities). We have:

P′x=γ(Px−βcE) P′y=Py P′z=Pz

with β and γ defined using the coordinate system velocity V:

γ≡11−V2c2−−−−−−√ β≡Vc.

Using the chain rule, we can write:

F′y≡dP′ydt′=dP′ydtdtdt′=dPy/dtdt′/dt.

However, we have from the Lorentz transformation for the time, that

t′=γ(t−βxc) ⇒ dt′dt=γ−γβcdxdtvx

Thus,

F′y=Fyγ(1−Vvxc2).

For the x component, we have (again, using the Lorentz transformation) that:

F′x≡dP′xdt′=dP′x/dtdt′/dt=γ(dPxdt−Vc2dEdt)γ(1−Vvxc2)

We have seen, however, from the definition of force, that dE/dt=F⋅v, and thus

F′x=Fx1−Vvx/c2−V/c2(Fxvx+Fyvy+Fzvz)1−Vvx/c2=Fx−V/c2(Fyvy+Fzvz)1−Vvx/c2

To summarize, the complete transformation is:

HideTransformation of Forces

F′xF′yF′z===Fx−Vc2(Fyvy+Fzvz)1−Vvxc2Fyγ(1−Vvxc2)Fzγ(1−Vvxc2).

If the velocity at S vanishes at a given moment (namely, that S is the rest frame of the particle), then v=0, and we have

F′x=Fx F′y=Fy/γ F′z=Fz/γ

(where S' is the system moving relative to the particle and S is the rest-frame).

when—without warning—something provokes your anger, you may struggle not to succumb to it. since what typically makes you mad is feeling powerless in the face of what seems unfair, your anger is mostly an attempt at a “quick fix” to right the balance. it’s as though you’re raising a fist in protest, proclaiming that you’re not going to capitulate to such injustice.

there are, however, a multitude of problems related to this immediate, push-back reaction of anger. and probably the key one is that almost never does it resolve the issue that gave rise to it. such reactive anger is probably best understood as self-defeating. as david burns, the author of the seminal self- book feeling good, observes: if realistically, acting on your anger is to make any sense, it needs to meet two criteria—which, in almost every case, is frankly impossible. that is, your anger must:

be directed toward a person who has intentionally (and needlessly) behaved in a hurtful way toward you; and

be beneficial or advantageous to you (i.e., assist you in achieving a desired goal).

i think you’ll agree that only rarely can you claim that your anger is both warranted and , whether to yourself or the relationship.

so let me offer you a two-step alternative to abandoning your better judgment and giving in to the temptation of anger—one that should neutralize your anger in seconds. or, when you’re really angry, in minutes.

but keep in mind that you must really want to execute these steps, be sufficiently motivated to perform them. which means overcoming more unconscious resistance than you might ever have imagined. because there are many immediate “advantages” of anger that can interfere with your resolve, i’ll suggest a few of them that might interfere with your employing this powerful method to rid yourself of counter-productive anger.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
