• Izibonelo zoMthetho Wesithathu kaNewton (empilweni yansuku zonke)

Isazi semvelo saseNgilandi u-Isaac Newton waqamba imithetho emithathu ebalulekile ephathelene nokunyakaza kwezidumbu, umbuzo obhekiswe koomakhenikha.

Imithetho, uma kukhulunywa ngokubanzi, ingachazwa kanjena:

• Umthetho wokuqala. Futhi kwaziwa ngaphansi kwegama le- Umthetho we-Inertia, ithi imizimba ihlale isesimweni sayo sokuphumula noma ngokunyakaza kwayo okufana nomugqa, ngaphandle kwalapho omunye umzimba unamandla athile kuyo.
• Umthetho wesibili. Obeye aziwe njengoIsisekelo esiyisisekelo se-dynamics, ithi isamba sawo wonke amandla asetshenzisiwe emzimbeni onikeziwe silingana nobukhulu bawo nokushesha kwawo.
• Umthetho wesithathu. Obeye aziwe njengo Umgomo wesenzo nokuphendula, iqinisekisa ukuthi okwamanje umzimba othize unamandla athile komunye, lo omunye ngaso sonke isikhathi uzoba namandla afanayo kuwo, kodwa ohlangothini oluhlukile. Kumele futhi kubhekwe ukuthi amandla aphikisayo azohlala etholakala kulayini ofanayo.

Izibonelo zoMthetho Wesithathu kaNewton (empilweni yansuku zonke)

1. Uma sigxuma sisuka esihlahleni singene emanzini, isihlenga siyahlehla, ngenkathi umzimba wethu uqhubekela phambili. Lesi yisibonelo somthetho wesithathu kaNewton njengoba kukhona isenzo (ukugxuma) nokuphendula (ukubuyiswa kwesihlenga).
2. Lapho sizama ukuphusha umuntu ngenkathi sisechibini. Okuzokwenzeka kithina, ngaphandle kwenhloso yomunye, sizobuyela emuva.
3. Lapho sibhukuda echibini, sibheka udonga bese siziphoqa ukuze sifinyelele umfutho. Kulokhu, kutholwa isenzo nokuphendula.
4. Lapho kushaywa isipikili, singena ngokujula singene phakathi okhunini lapho sishaywa ngesando, isando senza ukunyakaza okubuyela emuva, okukhonjwa njengokusabela kokushaya kwaso.
5. Lapho umuntu edudula omunye onomzimba ofanayo, ngeke nje lowo muntu ahlehlele emuva, kodwa futhi nalowo omcindezele.
6. Lapho sigwedla isikebhe, ngenkathi amanzi siwahlehlisa sibheke emuva, amanzi asabela ngokucindezela isikebhe siye kolunye uhlangothi.
7. Lapho abantu ababili bedonsa intambo efanayo ezinhlangothini eziphambene futhi ihlala endaweni efanayo, kuyabonakala nokuthi kunesenzo nokuphendula.
8. Lapho sihamba, ngokwesibonelo, ogwini, ngenkathi izinyawo zethu zisebenza ngamandla phambili ngesinyathelo ngasinye, sibuyisela isihlabathi emuva.
9. Ukusebenza kwendiza kuyenza iqhubekele phambili ngenxa yokuthi ophephela bacindezela ohlangothini oluhlukile, okungukuthi, emuva.
10. Irokhethi lihamba ngenxa yomoya oshiswa yisibhamu. Ngakho-ke, ngenkathi ibuyela emuva ngesenzo samandla, irokhethi liqhubekela phambili ngesenzo samandla afanayo kepha liqonde kolunye uhlangothi.
