Ariā Kinetika
Ka taea te whakamārama i te tukanga mimiti mā te whakamahi i te ariā nekeneke. Pērā i ngā ngota hau, ka neke hoki ngā ngota wai. Ko te rerekētanga, kāore e taea e ngā ngota wai te wehe nā te mea kei te kaha tonu ngā kaha kukume i waenganui i a rātou ki te pupuri i a rātou. He rerekē, he ngoikore rawa ngā kaha kukume i waenganui i ngā ngota hau, nō reira kāore e taea e ngā ngota hau te piri tahi. Ina neke, he tere ngā ngota wai. He tere teitei ētahi ngota wai, he iti ētahi. He rite te tohatoha o ngā tere ngota wai ki te tohatoha Maxwell.
Ka puta te mimiti ina nui te tere o ngā ngota wai, ā, kāore e taea e te kaha kukume i waenga i ngā ngota wai te pupuri i a rātou kia kotahi. He rite ki te rōkete e neke ana ki te wāhi, he nui te tere o te rōkete, ā, kāore e taea e te kaha ā-papa te aukati i a ia kia noho ki runga i te whenua. Me mōhio ko ngā ngota anake he tere nui ka taea te mawhiti mai i ngā kaha kukume i waenga i ngā ngota. Ka honoa tonu ngā ngota he iti te tere hei hanga wai.
He papatipu, he tere, he tere rānei ngā ngota wai, nō reira he kaha nekeneke ngā ngota wai (EK = 1/2 mv 2 ). He nui ake te kaha nekeneke o ngā ngota wai he tere teitei i ngā ngota wai he tere iti. Nō reira, ka taea te kī he nui rawa te kaha nekeneke o ngā ngota wai ka taea te mawhiti i ngā kaha kukume i waenga i ngā ngota (ngota wai ka huri hei mamaoa). I te nuinga o te wā ka piki ake te kaha nekeneke o ngā ngota wai i te pikinga o te pāmahana wai. Mena he nui te pāmahana o te wai, ka piki ake te kaha nekeneke o ngā ngota wai. Nō reira, ka nui ake te wai ka huri hei mamaoa. E rite ana tēnei ki ngā hua rangahau e whakaatu ana he nui ake te tere o te mimiti i ngā pāmahana teitei.
Ina whakamarokehia ngā kākahu mākū i te rā, ka mimitihia e ngā kākahu mākū te wera e tukuna ana e te rā. Mā te pūngao tāpiri mai i te rā ka piki ake te pūngao nekeneke o ngā ngota wai i roto i ngā kākahu. Nā te pikinga o te pūngao nekeneke, ka tere ake te neke o ngā ngota wai (ka piki ake te tere o ngā ngota wai). Kia tae atu tō rātou tere, tō rātou pūngao nekeneke rānei ki tētahi uara, ka taea e ngā ngota wai te mawhiti i ngā kaha kukume i waenga i ngā ngota wai, kātahi ka huri hei mamaoa. He mea nui kia mōhio ko te whakamaroketanga o ngā kākahu mākū ehara i te mea ko te wera tāpiri mai i te rā anake te mea e pāngia ana. Ka taea hoki e ngā kākahu mākū te maroke nā te wera tāpiri mai i te hau mahana e karapoti ana i ngā kākahu (ka whakawhitihia te wera mā te kawe wera mai i te hau ki ngā kākahu mākū).
I te rā wera, ka tere ake te wera o te whenua, o te papa rānei. Ka tere te wera o te whenua nā te mea he nui tōna wera motuhake. Ka whakamahana te whenua i te hau i runga ake (i tēnei wā, ka puta te whakawhiti wera mā te kawe hiko). Ka whānui te hau wera (ka heke tōna mātotoru) ka neke ake. Ina pā ki runga i ngā kākahu mākū, ka tukinga ngā ngota hau ki ngā ngota wai i roto i ngā kākahu. Ka tere ake te neke o ngā ngota wai. Nā te mea ka tere ake tā rātou neke, ka piki ake te kaha nekeneke o ngā ngota wai. Ka tukinga ngā ngota wai tere ki ētahi atu ngota wai. Nā te mea ka tukinga tonu rātou e ngā ngota hau, ka tere ake te neke o ngā ngota wai (ka piki ake tō rātou kaha nekeneke).
Kia tae atu tō rātou tere, tō rātou kaha nekeneke rānei ki tētahi uara, ka taea e ngā ngota wai tere te mawhiti i te kukume i waenga i ngā ngota ka huri hei mamaoa… He hononga tata te kaha nekeneke o ngā ngota wai, o ngā ngota hau rānei ki te pāmahana. Mena he nui te kaha nekeneke o ngā ngota wai, he teitei te pāmahana o te wai i taua wā anō. Mēnā rānei, ina teitei te pāmahana o te wai, me nui te kaha nekeneke o ngā ngota wai. E pā ana hoki te kaha nekeneke ki te tere. Ko te nui ake o te kaha nekeneke o ngā ngota, ko te nui ake o te tere o ngā ngota. Mēnā rānei, ko te nui ake o te tere o ngā ngota, ko te nui ake o te kaha nekeneke o ngā ngota.
Ā, me pēhea te wai wera? He teitei te pāmahana o te wai wera. Nā te mea he teitei te pāmahana o te wai, he nui te kaha nekeneke toharite o ngā ngota wai i roto i te wai. Nā te mea he nui te kaha nekeneke toharite o ngā ngota wai, he tere te neke o ngā ngota wai (he tere te neke o ngā ngota wai). Ka taea e ngā ngota wai he tere teitei te mawhiti i ngā kaha kukume i waenga i ngā ngota ka huri hei mamaoa. Ko ngā ngota wai he tere teitei anake (ngota wai he nui te kaha nekeneke) ka mawhiti ki te mamaoa, engari ko ngā ngota wai he iti te tere (ngota wai he iti te kaha nekeneke) kāore e huri hei mamaoa. Nō reira, ina huri ngā ngota wai he tere teitei ki te mamaoa, ka iti ake te kaha nekeneke toharite o ngā ngota wai e noho tahi ana. Ka iti ake te kaha nekeneke toharite, ka iti ake te pāmahana wai (ka makariri ake te wai). I runga i tēnei whakaahuatanga poto, ka taea te kī he tukanga whakamatao te mimiti.
He mea noa te tukanga whakamatao e puta mai ana i te mimiti i roto i te oranga o ia rā. Ina tino wera te hau, ka mimiti te tinana i te nui o te wera. Hei pupuri i te pāmahana tinana pumau, ka tukuna te wera e te tinana mā te werawera. Nā te mea ka whiwhi te werawera i te werawera i te werawera mai i te rā me te hau e karapoti ana, ka piki ake te kaha nekeneke o ngā ngota werawera. Nā te mea ka piki ake te kaha nekeneke o ngā ngota werawera, ka piki ake te tere o ngā ngota werawera. Ka huri ngā ngota werawera hei kohu. Ina mimiti te werawera, ka mātao te tinana. Anei tētahi atu tauira... I muri i te kaukau, ka mātao te tinana. Nā te mea ka mimiti te wai e piri ana ki te mata o te kiri.
Ka puta te tukanga mimiti kua whakaahuatia i runga ake nei i ia rā, i ia rā. Ka taea hoki e te wai moana, te wai roto, me te wai awa te mimiti…
Pēhanga Kohu
Ko te tikanga o te mamaoa i konei ko te mamaoa wai. Mātakitakina te pikitia. He ipu kua kati kua whakakiia ki te wai (me kī kua tangohia te hau i roto i te ipu). E ai ki te ariā nekeneke, kei te neke tonu ngā ngota wai. I te nekeneke, he tere me te kaha nekeneke ngā ngota wai. Ka taea e ngā ngota wai he tere me te kaha nekeneke te mawhiti i ngā kaha kukume i waenga i ngā ngota wai ka huri hei mamaoa... Ka puta te tukanga kotahi ki ngā ngota wai i roto i te ipu i tōna taha. I te haere o te wā, ka nui haere ngā ngota wai ka huri hei mamaoa. Nā te mea kua kati te ipu, kāore e taea e ngā ngota wai kua huri hei mamaoa te mawhiti ki te āhuarangi (kua mau ngā ngota i roto i te ipu). He nui te maha o ngā ngota wai e huri ana hei mamaoa kia tūpono ai te tukinga i waenga i ngā ngota me ngā pakitara o te ipu.
Ko ētahi o ngā ngota e pā ana ki ngā pakitara o te ipu ka whakaatahia ki te mata o te wai, ka honoa hei wai. Ka haere tonu tēnei tukanga. I te haere o te wā, ka nui haere ngā ngota wai ka huri hei kohu (ka huri mai i te wai ki te kohu). I taua wā anō, ko ētahi o ngā ngota e pā ana ki ngā pakitara o te ipu ka huri anō hei wai (ka huri mai i te kohu ki te wai). Mena he rite te maha o ngā ngota e huri ana mai i te wai ki te kohu ki te maha o ngā ngota e huri ana mai i te kohu ki te wai, ka puta te taurite. Ina puta te taurite, ka kiia te tihi o te ipu kei roto te kohu he mākū… Ko te pēhanga kohu i te rohe mākū e mōhiotia ana ko te pēhanga kohu kūkū.
Ko te huringa mai i te wai ki te kohu ka kiia ko te mimiti. Ko te huringa mai i te kohu ki te wai ka kiia ko te hauhautanga. Kia mahara ko te pēhanga kohu kukū ka whakawhirinaki anake ki te pāmahana, ehara i te rōrahi. I te pikinga ake o te pāmahana o te wai, ka piki ake te kaha nekeneke o ngā ngota wai.
Ka piki ake te kaha nekeneke o ngā ngota wai, ā, me piki ake te tere o ngā ngota wai. Mā tēnei, ka nui haere ngā ngota tere ka huri hei kohu (ka huri te āhua mai i te wai ki te kohu). Nā te mea he pumau te rōrahi o te ipu, ko te pēhanga kohu ka whakawhirinaki anake ki te maha o ngā ngota (N) me te tere (v).
Ko te nui ake o ngā ngota ngota (ko te nui ake o te N) e huri ana hei kohu, me te tere ake o ēnei ngota ngota (ko te nui ake o te v), ka piki ake te pēhanga kohu. Nō reira, ka puta te taurite i te pēhanga kohu teitei ake. Nō reira, ka piki ake hoki te pēhanga kohu kua mākū. Ka noho te pēhanga kohu kua mākū ina tae ki te taurite. E whakaatu ana te mea e whai ake nei i te huringa o te pēhanga kohu kua mākū o te wai me te pāmahana.
Ko te pēhanga o te kohu e whakawhirinaki ana ki te rōrahi, engari kāore te pēhanga o te kohu kua mākū. Mēnā ka piki, ka heke rānei te rōrahi o te ipu, ka tutuki te taurite i te mutunga. Ko te whakaahua i runga ake nei he ārahi noa iho i a koe ki te mārama ki te pēhanga kohu kua mākū e puta ana i te āhuarangi. Ko te rerekētanga, i roto i te whakaahua o mua, i whakaaro mātou kāore he hau i roto i te wāhanga o te ipu kāore he wai. Nō reira, ko te wāhanga o te ipu kāore he wai i nohoia e te kohu wai anake. He rerekē, ko te mata o te Ao e kī tonu ana i te hau. Ko ngā tukinga i waenga i ngā ngota kohu me ētahi atu ngota hau ka roa ake te wā e pau ana kia tutuki te taurite. Heoi, ka tutuki te taurite i te mutunga ina rite te maha o ngā ngota wai e huri ana hei kohu ki te maha o ngā ngota kohu e huri ana hei wai.
