Motion translational

Yintoni na intshukumo okuqhubekayo? incwadi School thina idibana ngokucacileyo lo mbuzo: isindululo phambili umzimba (Qaphela, into efanelekileyo - "umzimba esiqinileyo nto!" - ATT, abunaluthando naluphi na uhlobo kwenzeka ukuba gqitha) - oko intshukumo apho nawuphi na umgca ngqo azotywe kuhlala onxusene ngokwayo ngexesha intshukumo yonke ngaphakathi emzimbeni (ATT).

Impendulo kubonakala ukuba alupheli. Ingcaciso unikwa, kwaye kwi-ajenda ngakwicala yeefom motion translational. Ekuqaleni, oku kunjalo elula isindululo efanayo rectilinear, ngoko - (! Kwaye kwakhona ngokungqongqo yomgama) i ezinokuntsonkotha umdla kokubuza iingqondo ravnoperemennoe intshukumo, umzekelo ocacileyo we yona ukuwa izidumbu. Phantsi eli candelo, umfundi ngokuya ebazi ngeepateni umdla, wathi ngolu hlobo lulandelayo:

1. Indlela babehamba liqumrhu phezu kumathuba alandelelanayo ezinxulumene njengoko wezikweri amanani zendalo: 1: 4: 9: 16 ...

yaye

2. Iindlela walihamba umzimba ngexesha ezilandelelanayo ngamathuba ixesha ngokulinganayo, zingqamene ngokweesirisi amanani angumnqakathi: 1: 3: 5, 9 ...

Ekucombululeni iingxaki zenzeka phakathi izixhobo ezifunekayo methodological kunye zemathematika, indlela umdla ukuyilungisa sesindululo, apho yonke idatha yokugcina lokuqala vice versa (intshukumo njengoko livela kwelinye icala, kunye Countdown). Le Dynamics uguqulo lonikezelo lwe lwephanyazo Velocity kumda wesangqa ye inkqubo onke amanqaku emendweni othe tye ukutshintsha indlela yayo ayitshintshanga kuphela ulwalathiso kumda wesangqa lunikezelo, ezinxulumene zemfuza ne kumda wesangqa isiphumo yonke imikhosi isicelo umzimba.

I 'Dynamics of motion yomgama " kwakunye yeefom, a priori kuthetha ukuba intshukumo somzimba obuqhubekayo ngokungqongqo, ngaphandle sijike naluphi axis kunye yobunzima lowo. Kungenxa yale meko pre-elikhankanyiweyo nga babesilela ubungakanani umzimba kumsebenzi, ucinga endaweni into efanelekileyo - le ngongoma eziphathekayo (MT) aba coincident nendawo kunye iziko womxhuzulane (CG) lomzimba. Noko ke, iziko lwenkobe ngaphambili wangena kwi "yeefom" kuba kwiimeko apho ubungakanani umzimba nokungahoywa kuthelekiswa ubude endleleni.

imithetho Conservation kwimeko sesindululo rectilinear kwakhona ingqalelo phantsi kweemeko xa abstract ukusuka ujikelezo kunokwenzeka umzimba ngokubeka intshukumo wakhe phambili (kungenjalo kuya kuqwalaselwa inguqu lwamacala intshukumo ojikelezayo zibe amandla amandla isindululo phambili kwaye umva)

Ngokufutshane, i sifundo kwikhosi physics zesikolo intshukumo phambili (esinda amelwe ityala ekhethekileyo isindululo ngapha komgca othe ngqo!) Libonelela ukutya obukhulu engqondo kunye nophando theoretical component. Awukwazi uthi malunga inxalenye zovavanyo kwekhosi yesikolo lifunda intshukumo progressive. ukusetha sokusebenza qualitative nje ndingekho okufundela ezininzi.

Kaloku ityala ekhethekileyo motion ngqo phambili ifundwa becala theory. Liyinyaniso elokuba, kungekhona into yokudlala, umatshini Atwood ngumsina yaye ngokukhawuleza kuzenzela abafundi ukwazi, ukuba ifakelwe ngokusisigxina ethile kwicala kude yemvelo lwekhabhinethi. iiyunithi Imiboniso ezifana ngokuwatshibiliza kunye ucingo wolula impahla ngokupheleleyo ingento, ekubeni kuzidyuplikheyitha self-olwaneleyo xa motion rectilinear, nto leyo twatse isindululo translational kwimeko jikelele. ngoko Yintoni bangacebisa? uphando search kuphela leyinene engqongileyo ngaphaya elabhoratri physics usebenzisa wit zendalo!

Siqhutywe umzekelo incwadi kweevili Ferris ( "lukaMtyholi Wheel"), undi neenafu kabani enze intshukumo ojikeleza ngaso, yaye ubonwa ngamehlo iminquba ezihambayo chu (! Nangona isangqa) kusenza siqiniseke ukuba inhlangano ATT (kwaye malunga - umzimba wokwenene) ingaba akukho ilula nje kuphela, kodwa abe nayiphi na indlela egosogoso (kule typology mzekelo ingqamana isikhokelo intshukumo ojikelezayo ze-MT).

Ingcamango ekufumaneni kumatyala inhlangano kwi lokudlala (kwimo iyahlolwa kwaye ingxoxo theoretical component) "ubuxoki kwenye indawo ekufutshane" kunye "ivili Ferris". Akuba eze kwibala lokudlala, siya kukwazi ukukhangela ukuba ngaba iintsalela kufana ngokwayo ngqo (efanisiweyo na isetyana okanye weMahalati obhityileyo) na isindululo komzimba kuzo zonke iintlobo zokulwa, roundabouts kunye simulators. Kucacile ukuba liya kuba ngokuqhubekayo ngaphandle kokuba ukuwa kwe kwiqumrhu engaphiliyo, baqhaqhe ezinye "isakhelo lisanyuka".

Ukuqinisekisa ukuba intshukumo translational enyulu amaninzi zifumaneka kwindalo nje ityala okhethekileyo - isindululo phambili yomgama, sikhanyise-heartedly nga phambili kwizinto zokufunda theoretical component incwadi yesikolo.
