Ngā rahinga ā-tinana Ngā waeine Ngā rahinga – Ngā raruraru me ngā otinga

1.

I runga anō i te ripanga i runga ake nei, ko ēhea ngā rahinga he waeine me he ine tūturu.

Rongoā:

1) Te nekehanga

Ko te whārite o te nekehanga ko p = mv

p = nekehanga, m = papatipu , v = tere

Te rahinga o te papatipu = M me te rahinga o te tere = L/T = LT ^-1 kia rite ai te rahinga o te nekehanga ki te MLT ^-1

Te waeine ā-ao mō te nekehanga = kg m/s = kg ms ^-1

2) Te kaha

Ko te whārite o te kaha ko F = ma

F = kaha, m = papatipu , a = whakaterenga

Ko te whānuitanga o te papatipu = M me te whānuitanga o te whakaterenga = L/T ² = LT ^-2 nō reira ko te whānuitanga o te kaha ko MLT ^-2

Ko te waeine ā-ao mō te kaha ko kg m/s ² = kg ms ^-2

3) Te mana

Ko te whārite o te mana ko W = F d

W = mahi, F = kaha, d = nekehanga

Ahu o te kaha = MLT ^-2 , ā, ko te ahu o te nekehanga ko L, nō reira ko te ahu o te mahi ko [M][L][T] ^-2 [L] = [M][L] ² [T] ^-2

Ko te whārite o te mana ko P = W/t

P = mana, W = mahi, t = wā

Ahu o te mahi = [M][L] ² [T] ^-2 me te ahu o te wā = [T] kia rite ai te ahu o te mana = [M][L] ² [T] ^-2 / [T] = [M][L] ² [T ] ^-2 [T] ^-1 = [M][L] ² [T] ^-3

Ko te waeine ā-ao mō te kaha ko kg m ² /s ³ = kg m ² s ^-3

2. E ai ki te ripanga i raro nei, ko ngā rahinga me ngā waeine me ngā ine tika ko….

Rongoā:

Ko te whārite o te nekehanga ko p = mv.

Ko te waeine papatipu (m) ko te kirokaramu (kg) ā, ko te waeine tere (v) ko te mita ia hekona (m/s) kia rite ai te waeine o te nekehanga ki te kg m/s, kg m/s rānei . Ko te kirokaramu te ine o te papatipu me te ine o [M], ko te mita te ine o te roa me te ine o [L], ko te hēkona te ine o te wā me te ine o [T] kia rite ai te ine o te nekehanga ki te [M][L]/[T] me te [M][L][T] ^{-1 rānei}.

Ko te whārite o te kaha ko F = ma.

Ko te waeine o te Papatipu (m) ko te kirokaramu (kg) ā, ko te waeine o te whakaterenga (a) ko te mita ia hekona tapawhā (m/s ² ) nō reira ko te waeine o te kaha ko te kg m/s ² , kg ms ^-2 rānei . Ko te waeine o te papatipu ko te kirokaramu me te ine o [M], ko te waeine o te roa ko te mita me te ine o [L], ko te waeine o te wā ko te hekona me te ine o [T] nō reira ko te ine o te kaha ko te [M][L]/[T] ² , ko te [M][L][T] ^{-2 rānei.}

Ko te whārite o te mana ko P = W/t , ko te whārite o te mahi ko W = F s, ko te whārite o te kaha ko F = m a.

Ko te waeine papatipu ko te kirokaramu (kg), ko te waeine whakatere ko te mita ia hekona tapawhā (m/s ² ) kia rite ai te waeine kaha ki te kg m/s ^2. Ko te waeine nekehanga ko te mita (m), ko te waeine kaha ko te kg m/s ² kia rite ai te waeine mahi ki te kg m/s ² xm = kg m ² /s ^2. Ko te waeine wā ko te hekona (s), ko te waeine mahi ko te kg m ² /s ² kia rite ai te waeine mana ki te kg m ² /s ² : s = kg m ² /s ³ , kg m ² s ^-3 rānei.

Ko te waeine o te papatipu ko te kirokaramu me te ine o [M], ko te waeine o te roa ko te mita me te ine o [L], ko te waeine o te wā ko te hēkona me te ine o [T] kia ko te ine o te mana ko [M][L] ² /[T] ³ rānei [M][L] ² [T] ^-3.

3. Ko te mana ka whakatauhia hei te tere o te mahi. Ko te mana rānei te ōwehenga o te mahi ki te wā. Whakatauhia te rahinga o te mana.

Rongoā:

Te whārite o te mana:

W = mahi, F = mana, a = whakaterenga, v = tere, d = tawhiti, t = wā

m = papatipu ( ahu o te papatipu = M), d = tawhiti (ahu o te tawhiti = L), t = wā (ahu o te wā = T).

Te whānuitanga o te mana:

1. He aha te rahinga ā-tinana?
   • whakahoki: Ko te rahinga ā-tinana he āhuatanga o tētahi mea, pūnaha rānei ka taea te ine me te ine. Ko ētahi tauira ko te papatipu, te roa, te wā, te pāmahana, me te kaha.
2. He aha te hiranga o ngā waeine i roto i te ine i ngā rahinga ā-tinana?
   • whakahoki: Mā ngā waeine ka taea te whakaatu i te rahinga o tētahi rahinga ā-tinana. Mā ēnei ka mārama, ka tika, ka ōrite hoki ngā inenga, ā, ka taea ai te whakawhitiwhiti kōrero me te māramatanga i waenga i ngā kaipūtaiao me ngā miihini o te ao katoa.
3. He aha te rerekētanga i waenga i te rahinga taketake (te rahinga pūtake rānei) me te rahinga i ahu mai?
   • whakahoki: Ko ngā rahinga taketake he rahinga ā-tinana taketake e whakatauhia motuhaketia ana, ā, koinei te pūtake mō ētahi atu inenga. Hei tauira, ko te roa, te papatipu, me te wā. Ka hangaia ngā rahinga i ahu mai i ngā huinga o ēnei rahinga taketake, pērā i te horahanga (roa x whānui) te tere rānei (tawhiti/wā).
4. He aha ngā inenga? He aha te hononga ki ngā rahinga ā-tinana?
   • whakahoki: Ko ngā inenga e pā ana ki te āhua me te momo o ngā rahinga ā-tinana (hei tauira, [L] mō te roa, [M] mō te papatipu, [T] mō te wā). E tohu ana ēnei i ngā mana e whakapiki ake ai ngā rahinga taketake hei tohu i tētahi rahinga ā-tinana.
5. He aha te tikanga o te "tātai ahu" o tētahi rahinga ā-tinana?
   • whakahoki: E whakaatu ana te tātai ahu i te whanaungatanga o tētahi rahinga ā-tinana i runga i ōna ahu taketake. Hei tauira, ko te tātai ahu mō te tere ko [LT^-1], e tohu ana ko te tere i ahu mai i te roa ([L]) i wehea ki te wā ([T]).
6. He aha te hiranga o te pūnaha SI (Aotearoa o ngā Waeine) i roto i te pūtaiao me te hangarau o ēnei rā?
   • whakahoki: Mā te pūnaha SI ka whakaratohia he huinga waeine paerewa e whakaaetia ana e te ao whānui mō te ine i ngā rahinga ā-tinana. Mā tēnei ka whakarite kia ōrite, ka whakaiti i te pōhēhētanga, ā, ka taea te mahi tahi i waenga i ngā kaipūtaiao me ngā miihini o te ao katoa.
7. He aha te rerekētanga i waenga i te rahinga tauine me te rahinga wetereo?
   • whakahoki: He rahi anake tō te rahinga tauine (hei tauira, te papatipu, te pāmahana), engari he rahi me te ahunga tō te rahinga whārite (hei tauira, te tere, te kaha).
8. He aha e kore ai e taea te whakamahi i ngā waeine tūpono hei ine i ngā rahinga ā-tinana?
   • whakahoki: Mā te whakamahi i ngā waeine tauwhāiti ka ara ake te rangirua, te kore e ōrite, me te kore e tika te whakawhitiwhiti kōrero i roto i ngā inenga me ngā tātaitanga pūtaiao. Mā ngā waeine paerewa ka mārama whānuitia ngā inenga, ā, ka taea te whakataurite.
9. He pēhea te whai huatanga o te tātaritanga ā-ahu i roto i te ahupūngao?
   • whakahoki: Mā te tātari inenga ka āwhina i te manatoko i te tika o ngā whārite ā-tinana mā te tirotiro i te ōritetanga o ngā inenga i ngā taha e rua o te whārite. Ka taea hoki te whakamahi hei whakatau i ngā whanaungatanga i waenga i ngā rahinga ā-tinana rerekē.
10. He aha i kiia ai ētahi rahinga, pērā i te taupū whakaata, te tauwehenga waku rānei, he kore-ahu?

• whakahoki: Ko ngā rahinga kore-ahu he ōwehenga o ngā rahinga ōrite, nō reira ka whakakorengia ō rātou āhua. Hei tauira, ko te taupū whakaata ko te ōwehenga o te tere o te mārama i roto i te korehau ki tōna tere i roto i te reo. Nā te mea he tere ngā mea e rua, ka whakakorengia ō rātou āhua, ka kore ai he āhua o te taupū whakaata.
