Inkqubo ye- Imithetho kaNewton, ekwabizwa ngokuba yimithetho yokuhamba, yimigaqo emithathu ye-physics ebhekisa kwisindululo semizimba. Ngaba:
- Umthetho wokuqala okanye umthetho we-inertia.
- Umthetho wesibini okanye umgaqo osisiseko weentshukumo.
- Umthetho wesithathu okanye umgaqo wesenzo kunye nokuphendula.
Le mithetho-siseko yaqulunqwa ngusosayensi wamaNgesi nakwingcali yezibalo, u-Isaac Newton emsebenzini wakheIfilosofi yendalo yesiseko semathematika (1687). Ngale mithetho, uNewton waseka iziseko zoomatshini abaphambili, isebe le-physics elifunda ngokuziphatha kwemizimba xa liphumle okanye lihamba ngesantya esincinci (xa kuthelekiswa nesantya sokukhanya).
Imithetho kaNewton yaphawula uguquko kwicandelo le-physics. Benza iziseko zenguqu (icandelo loomatshini abafunda ngokuhamba ngokwemikhosi eyayisusile). Ngaphaya koko, ngokudibanisa le mithetho-siseko nomthetho womxhuzulane kwindalo iphela, kunokwenzeka ukuchaza imithetho yesazi ngeenkwenkwezi nesazi semathematika saseJamani, uJohannes Kepler, kwisindululo seeplanethi kunye nesathelayithi.

Umthetho wokuqala kaNewton-Umgaqo we-Inertia
Umthetho wokuqala kaNewton uthi umzimba utshintsha isantya saso kuphela ukuba kukho amandla asebenza kuwo. I-Inertia lutyekelo lomzimba ekufuneka lulandelwe kwimeko ekulo.
Ngokwalo mthetho wokuqala, umzimba awunakuguqula imeko yawo ngokwawo; ukuze iphume ekuphumleni (isantya esinguziro) okanye intshukumo efanayo yomjikelo, kuyafuneka ukuba inyanzelise okuthile kuyo.
Ke ngoko, ukuba akukho mandla asetyenziswayo kwaye umzimba ukwimeko yokuphumla, uyakuhlala unjalo; ukuba umzimba ubushukuma, uya kuqhubeka nokuhamba ngokufanayo ngesantya esiqhubekayo.
Njengokuba:Indoda ishiya imoto yayo ipakwe ngaphandle kwendlu yayo. Akukho mandla asebenzayo emotweni. Ngosuku olulandelayo imoto isekhona.
UNewton ukhupha umbono we-inertia kwisazinzulu sase-Italiya, uGalileo Galilei (Ingxoxo kwiinkqubo ezimbini ezinkulu zehlabathi -1632).
Umthetho weSibini kaNewton-Umgaqo osisiseko weDynamics
Umthetho wesibini kaNewton uthi kukho ubudlelwane phakathi kwamandla anyanzelekileyo emzimbeni kunye nokukhawulezisa kwawo. Obu budlelwane buchanekile kwaye bulingana, Oko kukuthi, amandla enyanzelwa emzimbeni alingane ngokuthe ngqo ekukhawuleziseni okuya kubakho.
Njengokuba: Amandla okusebenza kukaJuan xa ekhaba ibhola, kokukhona kunokwenzeka ukuba ibhola iwele phakathi kwinkundla kuba kokukhona iya kukhawulezisa ngakumbi.
Ukukhawulezisa kuxhomekeke kubungakanani, kwicala, kunye nokuqonda kwamandla asetyenzisiweyo, kunye nobunzima bento.

Umthetho wesithathu kaNewton-Umgaqo wokuSebenza kunye nokuSebenza
Umthetho wesithathu kaNewton uthi xa umzimba unamandla komnye, lo wamva uphendula ngempendulo enobungakanani obulinganayo kunye nolwalathiso kodwa kwelinye icala. Amandla anyanzeliswa sisenzo ahambelana nempendulo.
Njengokuba: Xa indoda ikhubeka phezu kwetafile, iyakufumana etafileni amandla afanayo nalawo awasebenzisileyo ngesibetho.
Imizekelo yoMthetho wokuQala kaNewton
- Umqhubi webhuleki yemoto kabukhali kwaye, ngenxa ye-inertia, udubula phambili.
- Ilitye emhlabeni likwimeko yokuphumla. Ukuba akukho nto iphazamisayo, iya kuhlala iphumle.
- Ibhayisekile egcinwe kwiminyaka emihlanu eyadlulayo eluphahleni iphuma kwimeko yayo yokuphumla xa umntwana ethatha isigqibo sokuyisebenzisa.
- Umdyarho weembaleki uyaqhubeka nokubaleka iimitha ezininzi ngaphaya komgca wokugqibela nokuba sele ethatha isigqibo sokuqhekeza, ngenxa ye-inertia yomzimba wakhe.

Imizekelo yoMthetho weSibini kaNewton
- Inenekazi lifundisa abantwana ababini ukukhwela ibhayisekile: oneminyaka emi-4 ubudala kunye nominyaka-10 ubudala, ukuze bafike kwindawo enye ngesantya esifanayo. Kuya kufuneka usebenze ngakumbi xa unyanzela umntwana oneminyaka eli-10 ubudala kuba ubunzima bakhe (kwaye ke ubunzima bakhe), bukhulu.
- Imoto ifuna isixa esithile samandla ehashe ukuze ikwazi ukujikeleza kuhola wendlela, oko kukuthi, ifuna amandla athile ukukhawulezisa ubunzima bayo.

Imizekelo yomthetho wesithathu kaNewton
- Ukuba ibhola enye yebhilikidi ibetha enye, kwawona mandla afanayo nakwesesibini nakweyokuqala.
- Umntwana ufuna ukutsiba akhwele emthini (reaction), kufuneka atyhale umhlaba ukuze aziqhubele (isenzo).
- Indoda ithoba ibhaluni; ibhaluni ityhala umoya uphume ngamandla alingana naleyo yenziwa ngumoya kwibhaluni. Kungenxa yoko le nto ibhaluni isiya kwelinye icala iye kwelinye.
