I- Imithetho kaNewton, eyaziwa nangokuthi imithetho yokunyakaza, yimigomo emithathu ye-physics ebhekisa ekunyakazeni kwemizimba. Ingabe:
- Umthetho wokuqala noma umthetho we-inertia.
- Umthetho wesibili noma isimiso esiyisisekelo se-dynamics.
- Umthetho wesithathu noma umgomo wesenzo nokusabela.
Lezi zimiso zakhiwa isazi sefilosofi saseNgilandi nesazi sezibalo, u-Isaac Newton emsebenzini wakheI-Philosophia naturalis Principia mathematica (1687). Ngale mithetho, uNewton wasungula izisekelo zemishini yakudala, igatsha le-physics elicwaninga ngokuziphatha kwezidumbu lapho liphumule noma lihamba ngesivinini esincane (uma kuqhathaniswa nejubane lokukhanya).
Imithetho kaNewton ibonakalise inguquko emkhakheni we-physics. Benza izisekelo zamandla (ingxenye yemishini ehlola ukunyakaza ngokuya ngamandla ayisungulayo). Ngaphezu kwalokho, ngokuhlanganisa lezi zimiso nomthetho wamandla adonsela phansi emhlabeni wonke, kungenzeka ukuchaza imithetho yesazi sezinkanyezi nesazi sezibalo saseJalimane, uJohannes Kepler, ngokunyakaza kwamaplanethi neziphuphutheki.

Umthetho Wokuqala KaNewton - Isimiso se-Inertia
Umthetho wokuqala kaNewton uthi umzimba uguqula kuphela ijubane lawo uma amandla angaphandle esebenza kuwo. I-Inertia ukuthambekela komzimba okumele kulandelwe kusimo okuso.
Ngokwalo mthetho wokuqala, umzimba awukwazi ukushintsha isimo sawo ngokwawo; ukuze liphume ekuphumuleni (zero speed) noma umnyakazo ohambelana nonoxande, kuyadingeka ukuthi amandla athile enze okuthile ngalo.
Ngakho-ke, uma kungekho mandla asetshenziswayo futhi umzimba usesimweni sokuphumula, uzohlala unjalo; uma umzimba ubuhamba, uzoqhubeka nokuhamba ngokufana ngejubane eliqhubekayo.
Ngokwesibonelo:Indoda ishiya imoto yayo ipakwe ngaphandle kwendlu yayo. Awekho amandla asebenza emotweni. Ngakusasa imoto isekhona.
UNewton ukhipha umqondo we-inertia kusosayensi wase-Italy, uGalileo Galilei (Ingxoxo ngezinhlelo ezimbili ezinkulu zomhlaba -1632).
Umthetho Wesibili KaNewton - Isisekelo Esisisekelo SeDynamics
Umthetho wesibili kaNewton uthi kunobudlelwano phakathi kwamandla asetshenziswa emzimbeni nokusheshisa kwawo. Lobu budlelwano buqondile futhi bulinganiselwe, okungukuthi, amandla afakwa emzimbeni alingana ngqo nokusheshisa ozoba nakho.
Ngokwesibonelo: Ukusebenza ngamandla kukaJuan lapho ekhahlela ibhola, maningi amathuba okuthi ibhola liwele maphakathi nenkundla ngoba ukushesha kwalo kuzoba kukhulu.
Ukusheshisa kuncike kubukhulu, ukuqondisa, nomuzwa wamandla asetshenzisiwe esewonke, kanye nobukhulu bento.
- Kungakusiza: Ukusheshisa kubalwa kanjani?
Umthetho Wesithathu kaNewton - Isenzo Sokwenza kanye Nendlela Yokuphendula
Umthetho wesithathu kaNewton uthi lapho umzimba usebenza ngamandla komunye, owokugcina uphendula ngokusabela ngobukhulu nokuqondiswa okulinganayo kepha kolunye uhlangothi. Amandla asetshenziswe isenzo ahambelana nokuphendula.
Ngokwesibonelo: Lapho indoda ikhubeka phezu kwetafula, izothola etafuleni amandla afanayo nawasebenzise ngokushaya.
Izibonelo Zomthetho Wokuqala KaNewton
- Umshayeli wemoto amabhuleki abukhali futhi, ngenxa ye-inertia, udubula phambili.
- Itshe phansi lisesimweni sokuphumula. Uma kungekho lutho oluphazamisayo, luzohlala luphumule.
- Ibhayisikili eligcinwe eminyakeni emihlanu eyedlule elisophahleni luphuma esimweni salo sokuphumula lapho ingane inquma ukulisebenzisa.
- Umjaho webanga elide uyaqhubeka nokugijima amamitha amaningi edlula entanjeni ngisho nalapho ethatha isinqumo sokubopha amabhuleki, ngenxa yesimo somzimba wakhe.

Izibonelo zoMthetho Wesibili KaNewton
- Intokazi ifundisa izingane ezimbili ukugibela ibhayisikili: eneminyaka engu-4 nengu-10, ukuze zifike endaweni efanayo ngokusheshisa okufanayo. Kuzofanele usebenzise amandla amaningi lapho ucindezela ingane eneminyaka eyishumi ubudala ngoba isisindo sayo (ngakho-ke nesisindo sayo), sikhulu.
- Imoto idinga inani elithile lamandla wehhashi ukuze ikwazi ukuzungeza emgwaqeni omkhulu, okungukuthi, idinga amandla athile ukusheshisa ubukhulu bayo.

Izibonelo zomthetho wesithathu kaNewton
- Uma ibhola elilodwa le-billiard lishaya elinye, amandla afanayo asebenza kowesibili njengasekuqaleni.
- Ingane ifuna ukugxuma ukugibela esihlahleni (ukusabela), kufanele iphushe umhlabathi ukuze izishukumise (isenzo).
- Indoda iphungula ibhaluni; ibhaluni liphusha umoya ngamandla alingana nalokho okwenziwa umoya kubhaluni. Yingakho ibhaluni lihamba lisuka kolunye uhlangothi luye kolunye.
