Pūngao Kinetic me te Rauemi Mahi Ahupūngao
Ki te pā te kaha kupenga ki tētahi mea, ka pāngia te mea e te whakaterenga (me te nekehanga). Ina pāngia te mea e te whakaterenga, ka rerekē tōna tere. Ka taea te kī ko te mahi i mahia e te kaha kupenga e pā ana ki ngā tere tīmatanga me ngā tere whakamutunga o te mea.
Ko te mahi i mahia ki runga i tētahi mea e te kaha katoa pumau:
Te kaha katoa (W) = Te kaha hua (F katoa) x te nekehanga (s)
E ai ki te Ture Tuarua o Newton, mēnā he kaha katoa e pā ana ki tētahi mea, ka pāngia taua mea e te whakaterenga.
Te mahi katoa (W) = (m)(a) s
Mena he pumau te kaha katoa, he pumau anō hoki te whakaterenga e pā ana ki te mea. Nō reira, ka taea e tātou te whakakapi i te whakaterenga (a) me te nekehanga (s) ki te whārite nekehanga raina tere ōrite.
Ngā Mōhiohio:
EKt = te pūngao nekeneke whakamutunga, EKo = pūngao nekeneke tīmatanga, m = papatipu, vt = te tere whakamutunga, vo = te tere tīmatanga.
Ko tēnei whārite ko te ariā pūngao mahi-kini . E kī ana te ariā pūngao mahi-kini ko te mahi hua, ko te kaha rānei i mahia e te kaha hua ki runga i tētahi mea, he ōrite ki te huringa o te pūngao kini o te mea. E kī ana hoki te ariā pūngao mahi-kini ko te pūngao kini o tētahi mea he ōrite ki te mahi katoa e hiahiatia ana hei whakatere i te mea mai i te okioki ki te nekehanga i tētahi tere, i te ritenga kē rānei.
