Umxholo
Ingcali yamachiza amaNgesi uIsaac Newton wavelisa imithetho emithathu ebalulekileyo enento yokwenza nokuhamba kwemizimba, umbuzo obhekiswa koomatshini.
Imithetho, ngokubanzi, inokuchazwa ngolu hlobo lulandelayo:
- Umthetho wokuqala. Kwakhona kwaziwa phantsi kwegama le Umthetho we-Inertia, ithi imizimba ihlala ihleli ikwindawo yokuphumla okanye ishukuma ngokufanayo, ngaphandle kokuba omnye umzimba unamandla athile kuyo.
- Umthetho wesibini. Kwaziwa njengeUmgaqo osisiseko weentshukumo, ithi isambuku sayo yonke imikhosi eyenziwayo emzimbeni othile siyalingana nobunzima kunye nokukhawulezisa.
- Umthetho wesithathu. Kwaziwa njenge Umgaqo wesenzo kunye nokuphendula, iyangqina ukuba ngalo mzuzu apho umzimba othile usebenzisa amandla athile komnye, eli elinye liya kuhlala linamandla afanayo kulo, kodwa kwelinye icala. Kufuneka ithathelwe ingqalelo ukuba imikhosi echaseneyo iya kuhlala ikumgca omnye.

Imizekelo yoMthetho weSithathu kaNewton (kubomi bemihla ngemihla)
- Ukuba sitsibela kwisihlenga singena emanzini, isihlenga siyabuya, ngelixa umzimba wethu uhambela phambili. Lo ngumzekelo womthetho wesithathu kaNewton okoko kukho isenzo (ukutsiba) kunye nokuphendula (ukubuyiswa kwesihlenga).
- Xa sizama ukutyhala umntu ngelixa echibini. Kuza kwenzeka ntoni kuthi, ngaphandle kwenjongo yomnye, siza kubuya umva.
- Xa siqubha echibini, sikhangela udonga kwaye sizityhale ukuze sifumane amandla. Kule meko, isenzo kunye nokuphendula nako kufunyenwe.
- Xa ubethelela isikhonkwane, siye singene nzulu emthini xa sibethwa ngesando, isando senza umva wokubuyela umva, ochongwa njengempendulo yesibetho saso.
- Xa umntu etyhala omnye onomzimba ofanayo, ayizukuphelela nje ukuba umntu atyhale ngasemva, kodwa ikwangulowo wamtyhalayo.
- Xa sibheqa isikhephe, ngelixa amanzi siwabeka umva ngepali, amanzi asabela ngokutyhalela kwelinye icala isikhephe.
- Xa abantu ababini betsala intambo efanayo kumacala ahlukeneyo kwaye ihlala kwindawo enye, kukwaqwalaselwa ukuba kukho isenzo kunye nokusabela.
- Xa sihamba, umzekelo, elunxwemeni, ngelixa iinyawo zethu sinyanzela phambili inyathelo ngalinye, siyityhalela ngasemva isanti.
- Ukusebenza kwenqwelomoya kuyenza iqhubele phambili ngenxa yeeturbines ezityhala zaya kwelinye icala, okt ngasemva.
- Irokethi ihamba ngenxa yombane otshiswa ngumlilo. Yiyo loo nto, lo gama ubuya umva ngokusebenza kwamandla, irokethi ihambela phambili ngokwenza kwaloo mandla kodwa kwicala elahlukileyo.
