Kusintha kwa madzi m'madzi - mavuto ndi mayankho Chiphunzitso cha Torricelli 1. Chidebe chimadzazidwa ndi madzi ndipo pali dzenje, monga momwe chithunzi chili pansipa. Ngati kuthamanga chifukwa cha mphamvu yokoka ndi 10 ms-2, kodi liwiro la madzi kudzera mu dzenjelo ndi lotani? Zodziwika: Kutalika (h) = 85 cm - 40 cm = 45 cm … Werengani zambiri

Ma static amadzimadzi - mavuto ndi mayankho Kuthamanga kwamadzimadzi 1. Kodi kusiyana kotani pakati pa kuthamanga kwamadzimadzi kwa magazi pakati pa ubongo ndi mapazi a munthu amene kutalika kwake ndi 165 cm (tiyerekeze kuti kuchuluka kwa magazi = 1.0 × 103 kg/m3, kuthamanga chifukwa cha mphamvu yokoka = 10 m/s2) Kudziwika : Kutalika … Werengani zambiri

Kukula kwa kutentha - mavuto ndi mayankho Kukula kwa dera 1. Chitsulo chachitsulo pa 20oC chili ndi kukula monga momwe zasonyezedwera pachithunzi chili pansipa. Ngati coefficient ya kukula kwa mzere wachitsulo ndi 10-5 oC-1 ndiye kusintha kwa dera pa 60oC ndi kotani. Kudziwika: Kutalika kwa chitsulo = 40 cm M'lifupi mwa chitsulo … Werengani zambiri

Momentum - mavuto ndi mayankho 1. Mpira wa 0.5-kg umayenda pa 2 m/s. Kenako mpira umamenyedwa ndi mphamvu F moyang'anizana ndi komwe mpira ukupita, kotero liwiro la mpira limasinthidwa kukhala 6 m/s. Mpira umakumana ndi wogunda kwa 0.01 sekondi, kodi kusintha kwa mphamvu ya mpira ndi kotani? Zodziwika: … Werengani zambiri

Kusunga mphamvu ya makina - mavuto ndi mayankho 1. Chipika cha m-kg chimatulutsidwa kuchokera pamwamba pa malo osalala, monga momwe chithunzi chili pansipa chikusonyezera. Kuyerekeza pakati pa mphamvu yokoka ndi mphamvu ya kinetic ya chipikacho pamalo M ndi… Yankho Mphamvu yokoka pa malo M: PEM = m … Werengani zambiri

Kukakamiza - mavuto ndi mayankho 1. Mpira wa 0.5 kg umagwa momasuka kuchokera kutalika kwa h1 = 7.2 metres ndipo umawonetsa kutalika kwa h2 = 3.2 metres. Kuthamanga chifukwa cha mphamvu yokoka = 10 m/s2. Dziwani kukakamiza. Kudziwika: Kulemera kwa mpira (m) = 0.5 kg Kutalika koyamba (h1) = 7.2 metres Kutalika kwachiwiri … Werengani zambiri

Kugundana kwa Mphamvu Yothamanga - Mavuto ndi Mayankho 1. Chipolopolo cha rabara cha magalamu 40 chinawombera mopingasa kukhoma, monga momwe chithunzi chili pansipa chikusonyezera. Chipolopolocho chikuwonetsedwa ndi liwiro lomwelo. Kodi kusintha kwa mphamvu ya mpira ndi kotani? Chodziwika: Kulemera (m) = magalamu 40 = 0.04 kg Kuthamanga koyamba (vo) = – … Werengani zambiri

Mphamvu ya mawu - mavuto ndi mayankho 1. Mapointi A ndi B ali pamtunda wa mamita 4 ndi mamita 9 kuchokera komwe kumachokera mawu. Ngati IA ndi IB zili pamtunda wa A ndi B, ndiye kuti IA: IB =… Yodziwika: Mtunda wa mfundo A kuchokera komwe kumachokera mawu (rA) … Werengani zambiri

Malo otsetsereka - mavuto ndi mayankho 1. Kulemera kwa chipika ndi 5 kg, kuthamanga chifukwa cha mphamvu yokoka = 9.8 m/s2, tan 37 o = 3/4. Kodi kuthamanga kwa chipikacho ndi chiyani? Yankho Lodziwika: kulemera (m) = 5 kg kuthamanga chifukwa cha mphamvu yokoka (g) = 10 m/s2 kulemera (w) = mg = (5)(10) … Werengani zambiri
