Ahupūngao Kura Tuarua

I roto i ngā rauemi mō te ture a Coulomb, i akohia te kaha i waenga i ngā utu hiko. I roto i te arotake i ngā mara hiko, i matapakihia tētahi atu momo ture a Coulomb, i whakaaturia mā te whārite F = q E, ko F te kaha hiko, ko q te utu hiko, ā, ko E te mara hiko. Ka taea te kī ko te ture a Coulomb he ture ahupūngao e whakamārama ana i te whanaungatanga i waenga i te utu hiko (q) me te mara hiko (E).

Te ture tiaki i te pūngao miihini

1. He pūngao ā-pūkaha pumau tō te mea, he pūngao nekeneke e piki haere ana, ā, he pūngao pūmanawa ā-papa e heke ana. Kei roto te mea i te āhua o….

1. diam
2. neke ake
3. neke ki raro
4. te neke haere ki runga i te tere haere

Kōrero
Ka nui ake te pūngao nekeneke, ka nui ake te tere o te mea, ā, ka iti ake te pūngao pūmanawa ā-papa, ka iti iho te teitei o te mea i runga ake i te whenua. Ka puta tēnei ina neke te mea mai i tētahi teitei ki raro ki te whenua.

Ko te papa hiko he mea i hangaia e te utu hiko, ā, ka pā ki te wāhi e karapoti ana i taua utu hiko, ko te awe o te papa hiko ka pāngia e ētahi atu utu hiko anake. Ina he utu hiko anō kei roto i te papa hiko i hangaia e te utu hiko, ka pāngia te utu hiko kē atu i te awe i roto i te āhua o te kaha hiko.

Ko te whakamāramatanga o te mara hiko, e ai ki te tuhinga mō ngā mara hiko, ka taea te mārama ki te hinengaro, engari ka taea hoki te whakaaro i roto i te hinengaro. Hei whakaahua i te mara hiko, ka whakaaturia ngā rārangi mara hiko. Ko ngā rārangi mara hiko he huinga rārangi kua tuhia huri noa i te utu hiko hei tohu i tōna aroaro. Nā te mea ko tā rātou whāinga he whakaatu i te aroaro o te mara hiko, he whanaungatanga kei waenganui i ēnei rārangi me te mara hiko. Arā, ka taea te whakamārama i te rahi me te ahunga o te mara hiko mā te hoahoa o ngā rārangi mara hiko.

I roto i te kaupapa o te Papa Hiko , kua matapakihia e tātou te whakamāramatanga me te tātai o te papa hiko ka taea te whakamahi hei tatau i te kaha o te papa hiko e puta mai ana i te utu hiko kotahi, i ētahi utu hiko, i te tohatoha rānei o ngā utu hiko. He ngāwari te whakatau i te kaha o te papa hiko e puta mai ana i te utu hiko kotahi, i ngā utu hiko e rua rānei mā te whakamahi i te tātai kaha o te papa hiko. Mēnā ko te kaha o te papa hiko e tatauhia ana e puta mai ana i te tohatoha utu hiko, he uaua ake te tatau mēnā ka whakamahia te tātai kaha o te papa hiko, engari he māmā ake mēnā ka whakamahia te ture a Gauss . I mua i te ako hohonu i te ture a Gauss, me mārama tuatahi ki te rerenga hiko nā te mea kei roto i te ture a Gauss te ariā o te rerenga hiko.

3 Ngā tauira o te whakawhiti wera mā te irahiko

1. Whakamāramahia te tikanga mā te whakamahi i ngā tauira te whakawhiti wera mā te irahiko ?
Kōrero
Ko te whakawhiti wera irahiko ko te whakawhiti wera i roto i te ahua o ngā ngaru hikohiko. Ko tētahi tauira o te whakawhiti wera irahiko ko te whakawhiti wera mai i te rā ki te Ao. Kei waenganui i te Ao me te rā he korehau, he tata korehau rānei, nō reira ko te wera e puta mai ana i te rā, i te pāmahana teitei ake, ki te whenua, i te pāmahana iti iho, kāore e taea te haere mā roto i te matū. Ko te mārama e puta mai ana i te rā ki te Ao he ngaru hikohiko, pērā i ētahi atu ngaru hikohiko, nō reira ka taea te whakatau ko te wera e neke ana mai i te rā ki te Ao i roto i te ahua o ngā ngaru hikohiko.

8 Ngā tauira o te whakawhiti wera mā te ara iahiko

1. Whakamāramahia te tikanga mā te whakamahi i ngā tauira te whakawhiti wera mā te arataki ?
Kōrero
Ko te whakawhiti wera mā te ara iahiko ko te whakawhiti wera e puta ana mā te tukinga i waenga i ngā ngota/ngota ngota e hanga ana i tētahi mea. Hei tauira, whakaarohia he pae rino kua wera. Ka pā tetahi pito o te rino ki te mura, ā, ka puritia tetahi pito. Ahakoa kāore te pito o te rino e puritia ana e pā ana ki te mura, nā te mea ka whakawhitia te wera mā roto i te pae rino, ka wera te pito o te rino e puritia ana. Me pēhea te whakawhiti wera mai i tetahi pito o te rino ki tetahi atu?
Ka whiwhi wera tāpiri te pito rino kua werahia. Ngā Kaora he pūngao e neke māori ana mai i ngā mea he pāmahana teitei ki ngā mea he pāmahana iti. Mā te pūngao tāpiri ka wiri haere ngā ngota/ngota e hanga ana i te rino mai i tō rātou tūranga taurite. I a rātou e wiri haere ana, ka tukinga ngā ngota/ngota ki ngā ngota/ngota tata, ka wiri haere ngā ngota/ngota, ka nui ake te pūngao e whiwhi ai. Ka haere tonu tēnei tukanga kia tae rā anō te wera ki te pito o te rino e puritia ana.

3 Ngā tauira o te whakawhiti wera mā te whakawhiti wera

1. Whakamāramahia te tikanga mā te whakamahi i ngā tauira te whakawhiti wera mā te whakawhiti wera ?
Kōrero
Ko te whakawhiti wera whakawhiti he whakawhiti wera e haere tahi ana me te nekehanga o te matū. Hei tauira, whakaarohia te wai i roto i te ipu konumohe e whakamahanahia ana i runga i te oumu. I te tīmatanga, ka whakawhitihia te wera mā te kawe me te irahiko mai i te mura ki te ipu konumohe, kātahi mā te kawe mai i te ipu konumohe ki te wai.
Ka tīmata te whakawhiti wera whakawhiti ina whiwhi te wai e tata ana ki tētahi ipu konumohe i tētahi wera tāpiri, ka whakanui ake i tōna pāmahana, kātahi ka whānui. Ka whakaitihia e tēnei whānui tōna mātotoru, ka mānu te wai ki te mata. Ka whakakapia tēnei wai e te wai he iti ake te pāmahana, he nui ake te mātotoru. Ka haere tonu tēnei tukanga, ka hangaia he ia whakawhiti i roto i te ipu. Ka mutu te tukanga ina tae katoa te wai ki te mata. te pāmahana taua wā anō rānei e koropupū ana te wai.
Ko tētahi atu tauira ko te hau. Ko te hau he hau e neke ana. Ka neke te hau kia taea ai te neke i te wera mai i ngā wāhi he teitei te pāmahana ki ngā wāhi he iti te pāmahana.
