Lamulo Loyamba la Newton amanena kuti chinthu chilichonse chomwe chili pa mpumulo chidzakhalabe pa mpumulo kapena ... kapena pa mpumulo ... Octobermayendedwe ofanana a mzere idzapitiriza kuyenda molunjika pa liwiro losasintha ngati mphamvu yonse, yomwe imadziwikanso kuti mphamvu yochokera pa chinthucho, ili yofanana ndi zero. Chiganizo cha masamu cha lamulo loyamba la Newton:
Taganizirani chinthu chomwe chikukuzungulirani, monga tebulo, mwala, kapena china chilichonse. Tebulo lomwe lili pamalo opumulira limakhalabe pamalo opumulira pokhapokha ngati lasunthidwa kapena kugonjetsedwa ndi mphamvu yakunja, monga kukankhira kapena kukoka. Izi ndi zomwezo ndi zinthu zina zomwe zili pamalo opumulira.
Kodi palibe mphamvu yomwe imagwira ntchito patebulo kapena pamwala kapena chinthu china chilichonse chomwe chili pampando? Pali mphamvu yomwe imagwira ntchito pa chinthucho, koma chiwerengero cha mphamvu zonse zomwe zikugwira ntchito pa chinthucho kapena mphamvu yomwe ikubwera ndi zero. Mphamvu yomwe imagwira ntchito pa chinthu chomwe chili pampando ndi mphamvu yokoka ndi mphamvu yachibadwa. Kulunjika kwa mphamvu yokoka kuli molunjika pansi kupita pakati pa Dziko Lapansi, pomwe kulunjika kwa mphamvu yachibadwa kuli molunjika mmwamba. Kukula kwa mphamvu ziwirizi ndi kofanana koma kosiyana ndi mbali, kotero mphamvu yotsatira ndi zero.
Nanga bwanji chinthu chomwe chikuyenda molunjika pa liwiro losasintha? Kuti timvetse bwino izi, tiyerekeze kuti mwakankhira chinthu, mwachitsanzo chidutswa cha chitsulo, pansi. Pambuyo pokankhira, chidutswa cha chitsulocho chimachepa kenako chimayima chifukwa cha kukhalapo kwa mphamvu yokanganaKuti zidutswa zachitsulo zisunthe kapena kuyenda nthawi yayitali, muyenera kusalala pamwamba pa pansi ndi pamwamba pa zidutswa zachitsulo. Pamene pamwamba pa pansi ndi pamwamba pa zidutswa zachitsulo zikuyenda bwino, zidutswa zachitsulo zimasuntha patali. Ngati pansi pali posalala bwino ndipo palibe kukangana, zidutswa zachitsulozo zimapitiriza kuyenda osasiya. Kodi palibe mphamvu yogwira ntchito pa chidutswa chachitsulo chomwe chikuyenda pamwamba pa pansi chosalala bwino? Pali mphamvu zomwe zimagwira ntchito pa zidutswa zachitsulo, zomwe ndi mphamvu yokoka ndi mphamvu yachibadwa. Mphamvu ziwirizi zimagwira ntchito molunjika ndipo sizimakhudza kuyenda kwa chidutswa chachitsulocho molunjika.
