Kaitirotiro pūngao tūpono
Te PE tō ā-papa = mgh — rongoā mō te pūngao, te nuinga, te teitei rānei, i runga i tētahi aorangi.

Ko nga pātai e pā ana
He aha te pūngao tūpono o te tō ā-papa?
Ko te pūngao e whiwhi ana tētahi ahanoa mā te whakatū i te tō ā-papa, PE = m × g × h. Ko te taumahatanga o te 2 kg i whakarewaina i te 10 m i runga i te Earth e rokiroki ana ki te 2 × 9.80665 × 10 ≈ 196 joules.
E whakawhirinaki ana te pūngao tūpono ki te tiketike tohutoro?
He. Ka inetia a PE e pā ana ki tētahi taumata kore i kōwhiria, i te nuinga o te wā ko te whenua. Ko ngā rerekētanga i te tiketike i waenganui i ngā pito e rua anake e whai tikanga ana.
He pēhea te rerekētanga o te tō ā-papa i ētahi atu aorangi?
Ko te PE e ōrite ana ki te g, nā reira ko te ōritetanga o te hau i te nui ake i te pūngao o Jupiter (g ≈ 24.8) ā, he iti iho i te Moon (g ≈ 1.62).
He pēhea te tatau i te tere o te pānga o te tūpāpaku?
Ka tae mai i te tiketike h, ka noho te pūngao tūpāpaku katoa ki te pūngao kinetic, nā reira ½mv² = mgh e tuku ana i te v = √(2gh) — motuhake i te taumaha. Mai i te 10 m i runga i te Earth, tata ki te 14 m/s, ā, ka whakaaturia e te tātaitai tēnei i te pūngao.
He pēhea te pānga o te pūngao tūpāpaku ki te pūngao whakarewa?
I te tūpāpaku o tētahi ahanoa, ka tahuri te pūngao tūpāpaku ki te pūngao ā-waha, i te wā e mau tonu ana te katoa (me te kore e whakaaro ki te ātete ā-waha). Ko te tikanga o te tiaki i te pūnga ko te take o te tere pānga i runga anō i te tiketike o te tūpāpaku, ehara i te nui.
He aha te rerekētanga i waenganui i te nui me te taumaha i tēnei wāhi?
Ka whakamahia e te tātai te taumahatanga i roto i ngā kīngā; ko te taumahatanga (te tōpana ā-papa) ko te m × g, ā, kua whakamātauria kētia ki roto i te kīanga PE = mgh mā te wā g, nā reira ka tāurutia e koe te taumahatanga, ehara i te taumahatanga.
