Imizekelo motion ngoomatshini. intshukumo Mechanical: Physics, Grade 10

Imizekelo intshukumo ngomatshini ezaziwa kuthi evela kubomi bemihla ngemihla. Oku abadlulayo iimoto,-ntaka, iinqanawa. Imizekelo elula intshukumo ngomatshini, siya ukudala thina, bedlula ngabanye. Wonke yesibini iplanethi yethu ityhalela xa moya ezimbini: iLanga axis yayo. Esi, ngokunjalo, imizekelo motion ngoomatshini. Ngoko ke ngoku sithethe ngale nto ngokungqalileyo.

Kwenzeka ntoni ubucukubhede

, Makhe sijonge yonke ekuthiwa ubucukubhede phambi ukuthetha, yintoni yimizekelo motion ngoomatshini. Asiyi kungena endle zenzululwazi zisebenze inani elikhulu ngokoMthetho. Ukuba sithethe ilula kakhulu, ubucukubhede - a isebe of physics ukuba ejongene isindululo lwemizimba. Yaye oko kusenokuba, le yimakhenikhi? Abafundi izifundo physics Uqhelene amacandelwana alo. Oku yeefom, izikhombisi statics.

Nganye yezahlulo nako ukufunda isindululo lwamaqumrhu, kodwa luphawu kuye kuphela ikakhulu. Ntoleyo, ngengozi, olusetyenziswa ekucombululeni iingxaki efanelekileyo. Masiqalise kunye yeefom. Nayiphi na incwadi isikolo mihla okanye resource yekhompyutha iza kwenza kucace ukuba isindululo a yeefom inkqubo ngoomatshini kuqwalaselwa ngaphandle kokuthatha ingqalelo izizathu ezikhokelela intshukumo. Ngelo xesha siyazi ukuba unobangela lunikezelo, nto leyo eya kubangela ukuba umzimba ihamba, ngamandla.

Kuthekani ukuba amandla kufuneka ucinge

Kodwa ucinga sele okwenziwa ifowuni ngoxa uqhuba ibandakanyeka kwicandelo elilandelayo, leyo kuthiwa okuhambisa. Isantya intshukumo Mechanical leyo yenye parameters ebalulekileyo nemiba enxulumene nethunga nale mbono. Owokugqibela macandelo - statics. Uye bafunda imiqathango kuvuselele kusetyenziso loomatshini. Umzekelo elula ndawonye ilixa iintsimbi elungelelanisayo. Qaphela ukuba ootitshala: isifundo physics, "intshukumo mechanical" esikolweni kufuneka uqale noku. Okokuqala, unike imizekelo, uze uwahlule ube ezintathu iindawo, ubucukubhede, yaye kuphela badlule abanye.

Yintoni imingeni

Nokuba ukuba bhekisa kuphela licandelo elinye, masenze wotshi ke yeefom, thina apha silindele inani elikhulu imisebenzi eyahlukeneyo. Eyona nto kukuba kukho iimeko ezininzi, ezisekelwe kuyo, umsebenzi inye kwenziwa ukukhanya eyahlukileyo. Ngaphezu koko, ingxaki kwi isindululo kinematic kungancitshiswa kwityala ukuwa. Oku ukuba sizakuxoxa ngoku.

Yintoni free-ukuwa kwi yeefom

Le nkqubo kunganika iinkcazelo ezimbalwa. Noko ke, baya ekugqibeleni kuncitshiswa zibe kwindawo enye. Xa ukuwa emzimbeni kuphela amandla womxhuzulane izenzo. Oku ngqo ezisuka embindini ubunzima bomzimba kunye embindini ukuya kumbindi womhlaba. Abanye kunokuba ulwimi "opholileyo" kunye neenkcazelo ngokukhawuleza kangangoko ufuna. Nangona kunjalo, ubukho omnye kuphela womxhuzulane ngexesha intshukumo loo kunyanzelekile.

Indlela yokusombulula iingxaki ekwindla simahla kwi yeefom

Okokuqala kufuneka 'ukufumana abambelele "ifomula. Ukuba ubuza utitshala mihla physics, uya kusabela ukuba ukwazi fomyula - sisiqingatha isisombululo. Ikota inikwe kwi ekuqondeni le nkqubo kunye kwenye ikota - kwinkqubo ukubala. Kodwa ifomula, ifomula kunye ifomula kwakhona - lo nto eyenza i uncedo.

Sinako kubiza ukuwa simahla kwityala elikhethekileyo motion ngokufanayo okukhawulezileyo. Kutheni? Ewe, ngenxa yokuba zonke izinto kuthatha. Ukukhawuleziswa akawatshintshi loo manqaku, akukho 9.8 yeemitha ngamnye ophindwe kabini yesibini. Ngenxa yesi sizathu, singakwazi udlulele. Umgama Formula babehamba ngumzimba xa ngokufanayo ekhawulezayo isindululo, uye ifomu: S = vot + (-) kwi ^ 2/2. Apha, S - umgama, Vo - sokuqala uqina, t - ixesha, a - lunikezelo. Ngoku siza kuzama ukuba zazise okubhalwe kule Ifomula kwimeko ukuwa.

Njengokuba besesitshilo ngaphambili, oku ityala ekhethekileyo motion ngokufanayo okukhawulezileyo. Ukuba - yinto eqhelekileyo ukukhawulezisa eqhelekileyo isikhundla, g in (kwaye endaweni) kuya kufuneka ixabiso article lwamanani, okwabizwa ngokuba tabular. Makhe ubhale umgama formula ngokuhamba umzimba kunjalo kuwa free: S = vot + (-) gt ^ 2/2.

Kuyabonakala ukuba kule meko intshukumo iya kwenzeka loo moya nkqo. Nceda sinikele ingqalelo into yokuba akukho ndlela leyi hi nga va ukusuka indlela ngasentla, elizimeleyo kobunzima bomzimba. Ngaba uza kuyilahla ibhokisi okanye ilitye, umzekelo, ukusuka kuphahla, okanye ngelitye ezimbini ezahlukeneyo - ezi zinto ngexesha elifanayo ekuqaleni ukuwa lawela phantse ngaxeshanye.

Yayoma. intshukumo Mechanical. imisebenzi

Hi ndlela leyi, kukho ikho into isantya nje ngephanyazo. Ibhekisela isantya nangaliphi na ixesha intshukumo. Kwaye ukuwa sinako ukubona lula, esazi nje izinga sokuqala. Kwaye ukuba zero, ityala ngokubanzi iqhekeza ikeyiki. Formula Velocity leso elishweni simahla kwi yeefom yefomu: V = Vo + gt. Qaphela ukuba i "- 'phawu yanyamalala. Emva kokuba ubeke, xa umzimba ehla. Yaye njengokuba umzimba inciphise ukuwa? Ngoko ke, ukuba uqina lokuqala ayenziwanga ingxelo, lwephanyazo nje lilingane imveliso womxhuzulane lunikezelo g ngexesha t ukuwa, sele iphelile ukususela ekuqaleni sentshukumo.

Physics. motion lomatshini ukuwa

Masishukume kwi kwiingxaki ezithile ngalo mba. Iqalise le meko zilandelayo. Abantwana bagqiba ukuba uyonwabele kwaye alahlele ibhola yentenetya ukuya eluphahleni lwendlu. Fumanisa oko isantya ibhola yentenetya ngalo mzuzu yempembelelo phantsi, ukuba indlu nemigangatho elinambini. Ukuphakama umgangatho omnye uzakubekwa ulingana eziimitha ezintathu. Ibhola ekhululwa esandleni.

Ukuhlangabezana nale mngeni akayi kuba mnye step-, njengokuba nawe ucinga ekuqaleni. Kubonakala ukuba konke kubonakala wayentswempu ezilula, ababambeleyo nje kwinamba oyifunayo kulo formula ye uqina lwephanyazo kunye bonke. Kodwa xa ngaba ukuze sikwazi ukumelana ingxaki: thina asazi ixesha ukuwa ibhola. Makhe sijonge ezinye iinkcukacha le ngxaki.

Dodge phantsi

Okokuqala, sinikwa inani imigangatho, kwaye siyazi ukuphakama ngamnye kubo. Kuyinto eziimitha ezintathu. Ngenxa yoko, nathi ngoko nangoko ukubala umgama eqhelekileyo ukusuka wophahla emhlabeni. Okwesibini, sixelelwa ukuba ibhola iphume esandleni. Njengesiqhelo, xa iingxaki intshukumo ngoomatshini (kwaye iingxaki ngokubanzi) kukho iinkcukacha ezincinane, leyo xa uqala ukuze kubonakale ngathi nantoni lebyi. Noko ke, kukho ibinzana uthi ibhola yentenetya akukho Velocity lokuqala. Excellent, omnye iikota kwifomula ithi shwaka. Ngoku kufuneka ukuba sibone ixesha, ayeba ibhola emoyeni phambi kokuba zicinywe emhlabeni.

Kuba oku kufuneka ifomula umgama ngentshukumo ngoomatshini. Okokuqala ukususa imveliso nesantya lokuqala ngexesha bentshukumo, ekubeni zero, kwaye kungoko imveliso iya kulingana zero. Okulandelayo, phinda macala ngo ezimbini bahlukane amaqhekeza. Ngoku singakwazi ukubonisa ixesha square. Ukuze oku kabini umgama bahlulwe ukukhawulezisa omxhuzulane. Siza nje ukuba singathatha ingcambu yalama cala eli binzana ukwazi ixesha elingakanani ngaphambi kokuba kwenzeke ingozi kwebhola emhlabeni. Tshintsha amanani iingcambu nencindi nokufumana malunga 2,71 kwimizuzwana. Ngoku nani endaweni kulo formula ye Velocity nje ngephanyazo. Thina ukufumana nama-26.5 ngomzuzwana.

Qaphela ukuba ootitshala kunye nabafundi ukuba uhambe kancinci enye indlela. Ukunqanda uphazamiseko kula manani, kufanele kube lula lula indlela lokugqibela. Oku kuza kuba luncedo kuba kuza ingozi encinane ulahlekile izibalo zabo, kwaye ubavumele isiphoso. Kulo mzekelo, siya luqhubeke ngolu hlobo lulandelayo: ukubonakalisa indlela yexesha umgama, kodwa kungekhona ukuze kufakwe amanani endaweni eli binzana kwifomula babe Velocity nje ngephanyazo. Emva koko wabona ngolu hlobo lulandelayo: V = g * SQRT (2 / g). Kodwa kukukhawuleziswa womxhuzulane ungenza ibinzana olukhulu. Ukuze wenze oku, kuya phambi kwindawo yembutho yesixeko. Thina bafumane V = SQRT (2 * g ^ 2 / g). Ngoku siza kunciphisa kukukhawuleziswa womxhuzulane kwinani elingezantsi kwaye kwinani ndicime degree yayo. Ngenxa yoko, nathi bafumane V = SQRT (2gS). Impendulo iya kuba efanayo, kuphela yokubala iza kuba ngaphantsi.

Iziphumo kunye nesiphelo

Ngoko ke, into esiyizamayo thina sifunde namhlanje? Kukho amacandelo ambalwa ukuba ufundwa physics. intshukumo Mechanical lohlulwe libe statics, izikhombisi yeefom. Nganye kwezi mini-Sciences uneempawu zawo, nto leyo zithathelwa ingqalelo xa zokusombulula iingxaki. Noko ke, thina ukunika uphawu jikelele ngqikelelo njengoko isindululo mechanical hlobo. 10 iklasi - isifundo kakhulu esebenzayo yale sebe yemvelo, njengako kwikharityhulam yezikolo. Ubucukubhede nayo iquka amatyala ukuwa, njengoko iimbono buso sesindululo ngokufanayo okukhawulezileyo. Yaye ezi zimo, ezenza yeefom.
