Me pēhea te ine i te tauwehenga o te whakahokinga
Kupu Whakataki
Ko te tauwehenga whakahoki (COR) he ine e whakamahia ana i roto i te ahupūngao me te hangarau hei whakaahua i ngā āhuatanga pīngore o te tukinga i waenga i ngā tinana e rua. Ka ine i te ōwehenga o ngā tere whanaunga i muri me mua o te tukinga, e whakaatu ana i te "pekepeke" o te tukinga. Ko te COR o te 1 e tohu ana i te tukinga pīngore tino tika, ko te COR o te 0 e tohu ana i te tukinga kore pīngore tino tika e piri tahi ai ngā mea. He mea nui te mārama me te ine i te COR i roto i ngā momo mara, tae atu ki te pūtaiao rauemi, te hangarau hākinakina, me te haumaru motuka. Ka tūhuratia e tēnei tuhinga te papamuri ariā, ngā tikanga, me ngā mahi mahi e hiahiatia ana hei ine tika i te tauwehenga whakahoki.
He Papamuri Tikanga
Ko te tauwehenga o te whakahokinga \( e \) e tautuhia ana i runga i te pāngarau penei:
\[ e = \frac{v_f – u_f}{u_i – v_i} \]
kei hea:
– \( v_f \) = te tere whakamutunga o te mea B i muri i te tukinga
– \( u_f \) = te tere whakamutunga o te mea A i muri i te tukinga
– \( u_i \) = te tere tīmatanga o te mea A i mua i te tukinga
– \( v_i \) = te tere tīmatanga o te mea B i mua i te tukinga
I roto i te horopaki o tētahi whakamātautau taka ngāwari (pērā i te takanga o te pōro ki runga i tētahi mata mārō), ka māmā ake te whārite ki:
\[ e = \sqrt{\frac{h_f}{h_i}} \]
kei hea:
– \( h_f \) = teitei i muri i te pekepeke
– \( h_i \) = te teitei tīmatanga o te takanga.
Ngā Tikanga mō te Ine i te Tauwehenga o te Whakahokinga
1. Tikanga Whakamātautau Taka
– Te Tatūnga: Ko tēnei tikanga ko te whakataka i tētahi mea mai i tētahi teitei e mōhiotia ana, me te ine i te teitei ka tae atu i muri i te pekepeke.
– Te Tukanga:
1. Inehia, ka tuhia te teitei tīmatanga (\( h_i \)).
2. Tukua te mea kia poutū ki runga i tētahi mata mārō, kāore e taea te whakapohehe.

4. Tātaihia te tauwehenga whakahokinga mā te whakamahi i te \( e = \sqrt{\frac{h_f}{h_i}} \).
– Ngā Painga: Māmā, iti te utu, he pai mō ngā mea iti, māmā hoki.
– Ngā Huakore: Kāore i te tino tika mō ngā mea kore-porowhita, ngā mata rānei he nui te rerekētanga o te āhua.
2. Tikanga Kāmera Tere-Teitei
– Tatūnga: Ka hopukina te tukinga e te kāmera tere-teitei, ā, ka hurihia kia mamati te nekehanga o ngā mea e pā ana.
– Te Tukanga:
1. Whakatūria he kāmera tere-teitei hei hopu i te tukinga mai i ngā koki maha.
2. Tukua, whakataka rānei te mea ki te mata o te tukinga.
3. Tātarihia te ataata i hopukina, anga-i-anga, hei whakatau i ngā tere tīmatanga me ngā tere whakamutunga.
4. Whakamahia ngā raraunga tere hei tatau i te COR mā te whakamahi i \( e = \frac{v_f – u_f}{u_i – v_i} \).
– Ngā Painga: Tino tika, e tika ana mō te whānuitanga o ngā momo mea.
– Ngā ngoikoretanga: He utu nui ngā taputapu, me te hiahia ki te mātauranga hangarau.
3. Tikanga Pendulum
– Tatūnga: He pūnaha pendulum e piu ai te pōro, e tukinga ai ki tētahi poraka tūmau.
– Te Tukanga:
1. Inehia, ka tuhia te koki tīmatanga me te teitei o te pendulum.
2. Tukua te pendulum ka tukua kia tukinga ki te poraka.
3. Inehia te koki me te teitei i muri i te tukinga.
4. Tātaihia te COR i runga i te panonitanga o te teitei.
– Ngā Painga: Taiao whakahaeretia, he iti ake te awe o ngā taurangi o waho.
– Ngā Huakore: He uaua te whakatakotoranga, kāore e pai mō ngā momo taonga katoa.
Nga Mahi Mahi
1. Te Kōwhiringa o ngā Taputapu:
– Kōwhiria he tikanga e tika ana i runga i ngā mea me ngā mata e whakamahia ana i roto i te whakamātautau. Me whakarite kia tika te whakatikatika i ngā taputapu ine katoa (ngā rūri, ngā kāmera, ngā pendulum).
2. Te Whakarite i te Taiao Whakamātautau:
– Me whakarite kia papatahi te mata, kia kore e taea te whakapēke mō ngā whakamātautau taka, kia whakaritea rānei he whakatakotoranga tukinga whakahaeretia mō ngā tikanga kāmera pendulum/tere-rahi. Whakaitihia ngā ia hau me ngā wiri ka pā ki ngā hua.
3. Te Whakahaere i te Whakamātautau:
– Whāia te tikanga kua tohua me te āta. Mō ngā whakamātautau maturuturu, kia tino tukuna te mea me te kore he takahuri tīmatanga, he tere whakapae rānei. Mō ngā whakamātautau kāmera tere-nui, kia tika te māramatanga me te tūnga o te kāmera. Mō ngā whakamātautau pendulum, kia tino nekeneke noa te pendulum me te kore he arai.
4. Te Tuhi me te Tātari Raraunga:
– Whakamahia ngā taputapu ine tika, ngā pūmanawa rānei hei tuhi i ngā raraunga e tika ana. Whakahoutia ngā whakamātautau kia maha ngā wā hei whiwhi i te uara toharite hei whakaiti i ngā hapa matapōkere.
5. Te Tātai i te Tauwehenga Whakahoki:
– Whakahaerehia ngā tātaitanga mā te whakamahi i ngā raraunga kua tuhia. Mō ngā whakamātautau maturuturu, whakamahia \( e = \sqrt{\frac{h_f}{h_i}} \). Mō ngā inenga tere uaua ake, whakamahia \( e = \frac{v_f – u_f}{u_i – v_i} \).
6. Te Whakamana i ngā Hua:
– Tirohia te COR kua tatauhia me ngā uara e mōhiotia ana mō ngā āhuatanga rauemi rite mai i ngā tuhinga. Aromatawaihia ngā rerekētanga katoa, ā, whakatikatikahia te whakatakotoranga whakamātautau mēnā e tika ana.
Nga tono me nga whakaaro
He mea nui te tauwehenga whakahoki i roto i ngā momo ahumahi. I roto i te haumaru motuka, ka āwhina i te hoahoa i ngā rohe pakaru me te mārama ki ngā whanaketanga pānga. I roto i ngā hākinakina, ka awe i te hoahoa o ngā pōro, ngā raketi, me ngā mata kia pai ai te mahi. Ka whakamahia e ngā kaipūtaiao rauemi te COR hei ako i te ātete pānga me te roa o ngā rauemi hou.
He mea nui kia whakaarohia ngā herenga o ō tikanga whakamātautau. Ka pāngia pea ō hua e te rerekētanga o te mata, te ātete hau, te pāmahana, me te kore ōrite o ngā rauemi. Nō reira, he mea nui te pupuri i tētahi taiao whakamātautau ōrite, whakahaeretia hoki, kia whiwhi ai i ngā raraunga pono.
Opaniraa
Mā te ine i te tauwehenga whakahoki ka kitea he māramatanga nui ki ngā āhuatanga ngāwari o ngā rauemi me ngā āhuatanga o ngā tukinga. Mā te whiriwhiri i te tikanga tika me te whai i ngā tikanga āta, ka taea te whakatutuki i ngā inenga tika. Ahakoa mō te rangahau mātauranga, mō ngā tono ahumahi, mō te whakawhanaketanga hua rānei, he mea nui te mārama ki te COR ki te whakatairanga i te hangarau me te whakarei ake i te mahi a te hua.
