Si kastaba ha ahaatee, waxaa kale oo jira qaababka caadiga ah: gaar ahaan, nooc kasta oo falalka kinematic lagu sheegi karaa by yahay ee dhidibka duwo. Sidaas darteed, mooshinka toosan waa dhabbihii a line toos ah, waxaa iska cad in ay magaca ka. Ha ka fikiro si aynu kiiska this si faahfaahsan.

mooshin rectilinear Lebis - dhaqdhaqaaqa, lagu gartaa dhaqaaqin fogfog siman dura siman waqti. Si fudud u gelin, waayo, mid kasta oo bareeg waqtiga la doortay (ama 1, 2, 3 seconds ama 10 daqiiqo), jidhka guulaysta masaafada gabi ahaanba waa loo siman yahay si wixii laydinka adkaan doonaa muddo waqti soo socda. Si adag u hadlayay, mooshin ku haboon toosan - model halkii aan la taaban karin, maxaa yeelay, si ay u gaaraan dhaqdhaqaaqa noocan oo kale ah ee xaaladaha caadiga ah waa ficil ahaan wax aan macquul aheyn, waxaa mar walba jira caqabado. iyaga ka mid ah - iska caabin ah hawada, muuqaalada iyo jidhka kale u dhaqaaqin.

formula ee mooshinka tani waa mid aad u fudud oo caan ah tan iyo dugsiga sare:

s = v / t,

halkaas s - masaafada u safray by jidhka muddo waqti go'an, v - xawaaraha lagu jiro dhaqdhaqaaqa this, t - waqtiga dhabta ah ee masaafada u. Caqli ahaan, xawaaraha mooshinkan sidoo kale waa joogto ah iyo is beddelin.

Ravnoperemennoe mooshin toosan - kiis gaar ah opisannnogo kor ku xusan iyadoo farqiga kaliya in halkan waxaan ku leeyihiin dhaqdhaqaaq la dardargelinta. formula ee sida soo socota:

s = vo + - AT2 / 2

Read sida: es (fogaanta) uyeelaysaan kuwo shan eber (xawaare hore), daro ama laga jaro a (xawaaraha) Te (waqti) afar gees kala qaybiyey laba. A "+ -" ma dhigay by shil. Xaqiiqada ah in mooshinka toosan ee xawaaraha waxaa laga yaabaa in a isku dedejiyey iyo ravnozamedlennym. Kiiska hore u dhiganta formula oo lagu daray labaad - laga jaray. Tusaalayaal: dardargelinta iyo deceleration ee tareenka. In the case of tareenka si ay u ururiyaan xawaaraha looga baahan yahay oo ma u baahan tahay dardargelinta dheeraad ah, waxa ay u guurayaan heerka xad joogto ah, taas oo, u qabata mooshin toosan.

Waxaa sidoo kale waa in ay tixgeliyaan noocan oo kale ah mooshin, sida sinnayn sahlan.

Si taas loo gaaro, wax sida xawaaraha celcelis ahaan sida la soo bandhigay. Its formula waa isku mid sida caanaha ee heerka uniform of XPIEIV:

v = s / t,

iyadoo farqiga kaliya in ay in search for meel gaar ah in hal dhibic gaar ah wakhti suurto gal ahayn, laakiin waxaan go'aan ka gaari kara waxa meel fog la dhameeyey gudahood waqtiga cayiman.

Marka la barbardhigo celceliska degdeg ah ugu XPIEIV sinnayn - xawaaraha in uu leeyahay jirka ah wakhti gaar ah.

Hadda oo waxyaabaha gaarka ah ee dhaqdhaqaaqa degdeg loo siman yahay, ka badan ama ka yar la furay, waxaa muhiim ah in la caddeeyo oo la kala mooshin rectilinear iyo curvilinear. Marka la eego xaqiiqada ah in mooshinka toosan ee makaanikada had iyo jeer ka dhigan tahay mid sahlan, waxaa xusid mudan, saynisyahano rumaysan in arrintaasi - kiis gaar ah curvilinear. Determination mooshin curvilinear waa sida soo socota: dhabbihii mooshin oo aan u dhiganta line toosan laakiin qalooca ah. Malaha ay sabab u tahay xaqiiqada ah in dhabbihii ku haboon si toos ah aanu jirin (oo keliya sida sidaynu ah), laakiin in inaga dhigay jidka toosan - kaliya qiimaha qiyaas per se, waxa run ahaantii la oran karo waa mooshinka toosan of view qalooca.
