Te Ture Tuarua a Newton e kī ana mēnā ehara te kaha hua i te kore, ka pāngia te ahanoa e te whakaterenga. He rite te rahi o te whakaterenga ki te rahi o te kaha katoa, ā, he rite whakamuri ki te papatipu o te ahanoa. He rite te ahunga o te whakaterenga ki te ahunga o te kaha katoa.
Mena he ōrite te rahi o te whakaterenga ki te kore, ka huri te whārite o te ture tuarua a Newton ki te whārite Te ture tuatahi a NewtonNō reira, he take motuhake te ture tuatahi a Newton ki te ture tuarua a Newton.
I runga i te whārite i runga ake nei, ka taea te whakatau ko te nui ake o te kaha, ko te nui ake o te whakaterenga. I tetahi atu taha, ko te nui ake o te papatipu, ko te iti ake o te whakaterenga. Ka mārama ake te whanaungatanga i waenga i te kaha, te papatipu, me te whakaterenga i muri i te whakahaere i ngā whakamātautau e pā ana ki tēnei. Ko tētahi whakamātautau ka taea te whakahaere ko te whakamātautau hei whakatere i tētahi tereina hihiri i runga i ngā rēri mā te whakamahi i tētahi papatipu e hinga noa ana. Whakamahia he taima tohu hei whakatau i te whakaterenga o te tereina.
Tauira raruraru.
1. Whakatauhia te rahi me te ahunga o te whakaterenga o te mea i runga i te ahua i raro nei!
Kōrero
E mōhiotia ana :
Taumaha (m) = 1 kg
Te kaha kume (F) = 4 Newton
I pātaihia : te rahi me te ahunga o te whakaterenga (a)
Whakautu :
Ko te rahi o te whakaterenga = 4 m/s2, te ahunga o te whakaterenga = te ahunga o te kaha hua = ki te taha matau.
2. Whakatauhia te rahi me te ahunga o te whakaterenga o te mea i runga i te ahua i raro nei!
Kōrero
E mōhiotia ana :
Taumaha (m) = 1 kg
Te kaha kume (F) = 4 Newton
Te kaha waku nekeneke (fk) = 1 Niutona
I pātaihia : te rahi me te ahunga o te whakaterenga (a)
Whakautu :
Ko te rahi o te whakaterenga = 3 m/s2, te ahunga o te whakaterenga = te ahunga o te kaha hua = ki te taha matau.
