Ko ēnei momo rahinga e rua te tūāpapa e hangaia ai ngā mātāpono me ngā ture o te ahupūngao. Ka rukuhia e tēnei tuhinga te … Pānuihia atu
He Whakamārama mō te Ariā Whakawhanaungatanga a Einstein Nā ngā ariā whakawhanaungatanga a Albert Einstein, arā, te Ariā Motuhake o te Whakawhanaungatanga (1905) me te Ariā Whānui o te Whakawhanaungatanga (1915), i huri te māramatanga ki te wāhi, te wā, me te kaha ā-papatipu. Ko ēnei ariā he pou o te ahupūngao hou, e awe ana i ngā momo mara mai i te ao tūroa ki te miihini irahiko. I roto i tēnei tuhinga, ka tūhuratia e mātou ngā kaupapa matua o ēnei ariā, … Pānuihia atu
# Ngā Tauira o ngā Raru Nekehanga Raina Āhua Ko te nekehanga raina āhua, e mōhiotia ana ko te nekehanga tapatoru āhua, e pā ana ki te nekehanga o tētahi mea i te tere pumau i runga i te ara tika. Ko tēnei momo nekehanga he tere pumau, e tohu ana kāore he whakaterenga. I roto i ngā mara maha pērā i te ahupūngao, te miihini, me ngā mahi o ia rā … Pānuihia atu
Te Mārama ki te Ture Tuatahi a Newton He mea hou ngā takoha a Tā Isaac Newton ki te pūtaiao, ā, ko tana Ture Tuatahi o te Nekehanga, e kiia ana ko te Ture o te Āhuakore, tētahi o ngā mātāpono matua o te ahupūngao. Mā tēnei ture ka whakatū te turanga mō ngā mahi miihini tawhito, ā, ka āwhina i a tātou ki te mārama ki te whanonga o ngā mea e neke ana, e … Pānuihia atu
3 ngā pātai mō te whārite taumaha
1. E toru ngā matūriki, he 1 kg te taumaha, kei ngā pito o tētahi tapatoru ōrite, ā, 1 m te roa o ōna taha. E hia te rahi o te kaha ā-papa e pāngia ana e ia matūriki pūwāhi (i roto i te G)?
otinga
Te rahi o te kaha ā-papa e pāngia ana e tētahi o ngā matūriki.
F 12 = G (m 1 )(m 2 ) / r 2 = G (1)(1) / 1 2 = G/1 = G
F 13 = G (m 1 )(m 3 ) / r 2 = G (1)(1) / 1 2 = G/1 = G

3 ngā pātai mō ngā whārite mara hiko
1. He pōro kawe hiko, he 10 cm te whānui, he 500 μC te utu hiko. Kei te rārangi o te pokapū o te pōro ngā pūwāhi A, B, me C i te tawhiti o te 12 cm, 10 cm me te 8 cm mai i te pokapū o te pōro. Tātaihia te kaha o te mara hiko i ngā pūwāhi A, B, me C!
Kua mohiotia:
Ko te radius o te pōro kawe (R) = 10 cm = 0.1 m
Utu hiko (q) = 500 μC = 500 x 10 -6 C
r A = 12 cm = 0,12 m
rB = 10 cm = 0,1 m
r C = 8 henimita = 0,08 mita
Pūmau Coulomb (k) = 9 x 10 9
E hiahiatia ana: Te kaha o te papa hiko i te pūwāhi A (E A ), i te pūwāhi B (E B ) me te pūwāhi C (E C )

3 ngā pātai mō te whārite pūmau puna
1. He 10 cm te roa o tētahi puna e whakatārewatia ana. I te pito whakatārewatia, ka whakatārewatia he taumaha 200 karamu kia 11 cm te roa o te puna. Mena ko te karamu = 10 m/s² , he aha te pūmau kaha o te puna?
Mōhiotia:
Ko te roa tīmatanga o te puna (y 1 ) = 10 cm = 0.10 m
Ko te roa whakamutunga o te puna (y 2 ) = 11 cm = 0.11 m
Te huringa roa o te puna (Δy) = 0.11 – 0.10 = 0.01 mita
Te papatipu o te kawenga (m) = 200 karamu = 0.2 kg
Taumaha kawenga (w) = mg = (0,2)(10) = 2 Newton
E hiahiatia ana: Pūmau puna (k)
