Sonke siqaphele ngezikhathi ezithile ukuthi uma sigibela simile ebhasini futhi lishaye ngokungazelelwe, umzimba wethu uvame "ukuqhubeka nokuhamba", okusiphoqa ukuthi sibambe ngokushesha into eqinile ngaphakathi ebhasini ukuze ingawi.
Lokhu kwenzeka ngoba imizimba ijwayele ukugcina isimo sayo, sokuphumula noma sokuhamba, ngaphandle kwalapho kwenziwa amandla. I-Physics ibona lesi simo njenge- "inertia".
I- inertia Kungukuphikisana nodaba oluphikisayo ukuguqula isimo salo sokuphumula noma ukunyakaza, futhi leso simo siguqulwa kuphela uma amandla asebenza kuzo. Kuthiwa umzimba une-inertia enkulu ephikisana kakhulu nokuguqula isimo sawo.

Izinhlobo ze-inertia
I-Physics ihlukanisa phakathi kwe-inertia yomshini ne-inertia eshisayo:
- Inertia yemishini. Kuya ngenani lenhlama. Uma umzimba unesisindo esikhulu, inertia iningi.
- I-inertia eshisayo.Kubala ubunzima lapho umzimba ushintsha ukushisa kwawo lapho uhlangana neminye imizimba noma lapho kushushubeziwe. I-inertia eshisayo incike ebuningini besisindo, ukuqhutshwa kokushisa, namandla okushisa. Uma umzimba ukhulu ngokwengeziwe, ukuqhuba okushisayo okuncane kunakho noma umthamo wokushisa owengeziwe onawo, kukhulu inertia yayo yokushisa.

Umthetho wokuqala kaNewton
Umqondo we-inertia uhlanganiswe nomthetho wokuqala we-inertia noma umthetho we-inertia, ngokusho kwawo uma umzimba ungaphansi kwesenzo samabutho, uzogcina ijubane lawo ngobukhulu nokuqondisa ngaso sonke isikhathi.
Kodwa-ke, kuyathakazelisa ukuphawula ukuthi ngaphambi kukaNewton, usosayensi uGalileo Galilei wayesewuphakamisile lo mqondo ngokubhekana nombono ka-Aristotelian emsebenzini wakhe.Izingxoxo ngezinhlelo ezimbili ezinkulu zomhlaba, iPtolemaic neCopernican, eyaqala ngo-1632.
Lapho uthi (emlonyeni womunye wabalingiswa bakhe) ukuthi uma umzimba ubungashibilika endizeni ebushelelezi futhi epholishiwe, ibizogcina ukunyakaza kwayoisikhangiso infinitum. Kepha uma lo mzimba ubungashibilika endaweni ethambekele, ubungaphathwa isenzo samandla angawenza usheshe noma wehlise (kuya ngokuya kokuthambekela).
Ngakho-ke uGalileo ubesenombono wokuthi isimo semvelo sezinto akusiso esokuphumula kuphela, kodwa futhi nesokunyakaza okunezinhlamvu ezilinganayo nokufana, inqobo nje uma engekho amanye amabutho asebenzayo.

Ihlotshaniswa nalo mqondo ophathekayo, lapho kuchazwa isimilo sabantu, kuvela enye incazelo yegama elithi inertia, elisetshenziswa kulawo macala lapho abantu bangenzi lutho ngokuthize ngenxa yokuvilapha, ukunamathela esimisweni, induduzo noma ngokumane bazivumele babe njengoba benjalo, okuvame ukuthi kube lula kakhulu.
Izibonelo ze-inertia empilweni yansuku zonke
Izimo eziningi zansuku zonke zibangela into ebonakalayo ye-inertia:
- Amabhande esihlalo angaphakathi. Bavala kuphela uma umzimba uqhubeka nokunyakaza lapho kukhona ukuma okungazelelwe.
- Umshini wokuwasha nge-spin. Isigubhu somshini wokuwasha sinemigodi emincane ukuze kuthi lapho ujikeleza ukuphotha izingubo, amaconsi amanzi anesivinini nesiqondiso esithile aqhubeke nokunyakaza kwawo futhi adlule emigodini. Kuthiwa-ke ukuthi inertia yamaconsi, isimo sokunyakaza abanakho, iyasiza ukususa amanzi ezingutsheni.
- Ukubamba ibhola ebholeni likanobhutshuzwayo.Uma umcibisheli engapheli ngezandla zakhe ibhola elifakwe ngumgadli weqembu eliphikisayo, kuzoba khona igoli. Ibhola elihambayo, ngenxa ye-inertia yalo, lizoqhubeka nokuya ngaphakathi kwegoli ngaphandle kokuthi amandla, lokho konozinti kuleli cala, alivimbele.
- Ukuphehla ngamabhayisikili. Singaqhubekisela phambili ngebhayisikili lethu amamitha ambalwa ngemuva kokugwedla futhi siyeke ukukwenza, i-inertia isenza sithuthuke kuze kube yilapho ukuqubuka noma ukungqubuzana kwedlula, bese ibhayisikili liyama.
- Ukuhlolwa kweqanda okuphekwe kanzima.Uma sineqanda esiqandisini futhi singazi ukuthi liluhlaza noma liphekiwe, silibeka ekhawunteni, siliphendule ngokucophelela bese sizama ukulimisa ngomunwe: iqanda elibiliswe kanzima lizoma ngokushesha ngoba okuqukethwe kwayo kuqinile futhi kwakha konke ngegobolondo, ukuze kuthi uma umisa igobolondo, kanjalo nengaphakathi. Kodwa-ke, uma iqanda liluhlaza, uketshezi olungaphakathi alumi masinyane kanye negobolondo, kepha luzoqhubeka nokuhamba isikhashana ngenxa ye-inertia.
- Susa indwangu yetafula bese ushiya okungaphezulu okuphumule etafuleni, endaweni efanayo. Icebo lomlingo lakudala elisuselwa ku-inertia; ukuze ulunge kufanele udonse indwangu yetafula phansi futhi into kufanele ibe lula. Into ehleli phezu kwendwangu yetafula iphikisana noshintsho esimweni sayo sokuhamba, ivame ukuhlala inganyakazi.
- Ukudubula okusebenza kumabhiliyade noma echibini. Lapho uzama ukufeza ama-caroms, usebenzisa i-inertia yamabhola.
