Lamulo Lachiwiri la Newton amanena kuti ngati mphamvu yochokera pa chinthu siili zero, chinthucho chidzathamanga. Kukula kwa kuthamanga kumafanana ndi kukula kwa mphamvu yonse ndipo motsutsana ndi kulemera kwa chinthucho. Kulunjika kwa kuthamanga ndi kofanana ndi komwe mphamvu yonse imapita.
Ngati kukula kwa kuthamanga kuli kofanana ndi zero, ndiye kuti equation ya lamulo lachiwiri la Newton imasintha kukhala equation Lamulo loyamba la NewtonKotero lamulo loyamba la Newton ndi chitsanzo chapadera cha lamulo lachiwiri la Newton.
Kutengera ndi equation yomwe ili pamwambapa, zitha kuganiziridwa kuti mphamvu ikakhala yayikulu, kuthamanga kumakulirakulira. Mosiyana ndi zimenezi, kulemera kukakhala kwakukulu, kuthamanga kumacheperachepera. Ubale pakati pa mphamvu, kulemera, ndi kuthamanga kumamveka bwino mutachita zoyeserera zokhudzana ndi izi. Kuyesera kwina komwe kungachitike ndi kuyesa kuthamangitsa sitima yoyenda pa njanji pogwiritsa ntchito kulemera komwe kumagwa momasuka. Gwiritsani ntchito nthawi yowerengera kuti mudziwe kuthamanga kwa sitimayo.
Chitsanzo cha mavuto.
1. Dziwani kukula ndi komwe chinthucho chikuthamangira pogwiritsa ntchito chithunzi chomwe chili pansipa!
Zokambirana
Ndizodziwika kuti :
Kulemera (m) = 1 kg
Mphamvu yokoka (F) = 4 Newton
Anafunsa : kukula ndi njira yothamangira (a)
Yankhani :
Kukula kwa kuthamanga kwa liwiro = 4 m/s2, njira yofulumizitsira = njira ya mphamvu yochokera = kumanja.
2. Dziwani kukula ndi komwe chinthucho chikuthamangira pogwiritsa ntchito chithunzi chomwe chili pansipa!
Zokambirana
Ndizodziwika kuti :
Kulemera (m) = 1 kg
Mphamvu yokoka (F) = 4 Newton
Mphamvu ya kukangana kwa kinetic (f)k) = 1 Newton
Anafunsa : kukula ndi njira yothamangira (a)
Yankhani :
Kukula kwa kuthamanga kwa liwiro = 3 m/s2, njira yofulumizitsira = njira ya mphamvu yochokera = kumanja.
