Ka taea te whakamahi i te tātaritanga ā-ahu i roto i te ahupūngao hei tirotiro i te tika o ngā putanga whārite. I roto i te tātaritanga ā-ahu, ko ngā rahinga ā-tinana anake me ngā rahinga ōrite ka taea te tāpiri, te tango, te whakataurite rānei. Mena ka whakareatia, ka wehea, ka whakanuia rānei ngā rahinga ā-tinana me ngā rahinga ōrite, rerekē rānei ki te mana, ka whakareatia, ka wehewehea, ka whakanuia rānei ngā rahinga o aua rahinga ki te mana.
Ngā rahinga me ngā ine taketake
Ngā rahinga i ahu mai me ngā inenga
He tauira o ngā pātai ine ahupūngao
| Ngā rahinga ā-tinana | Ngā tātai rahinga ā-tinana | He aha te moni matua kei roto? | Ahu | Wāhanga |
| Te horahanga o te porowhita | Pi x tapawhā o te pūtoro (pī r2) | Roa (2) | [L2] | m2 |
| Te horahanga o te tapawhā hāngai | Roa x whānui | Roa (2) | [L2] | m2 |
| Rohe tapawhā | Sisi x Tuhinga | Roa (2) | [L2] | m2 |
| Te horahanga o te pōro | 4 x pi x tapawhā o te pūtoro (4 pi r2) | Roa (2) | [L2] | m2 |
| Pūngao nekeneke | ½ x Tuhinga x te tapawhā o te tere (½ mv2) | Papatipu (1), roa (2), wā (2) | [M][L]2]/[T2] | kg m2/s2 |
| Pūngao pūmanawa ā-papa | Maha x te whakaterenga nā te kaha ā-papa x teitei (mgh) | Papatipu (1), roa (2), wā (2) | [M][L]2]/[T2] | kg m2/s2 |
| Pakihi | Gaya x nekehanga (Fs) | Papatipu (1), roa (2), wā (2) | [M][L]2]/[T2] | kg m2/s2 |
I runga i ngā tauira o runga ake nei, ka taea te whakatau ahakoa he rerekē ngā tātai o te horahanga o te porowhita, te horahanga o te tapawhā rite, te horahanga o te tapawhā rite, me te horahanga o te porowhita, he rite tonu ngā rahinga me ngā waeine o ēnei rahinga, nō reira e kiia ana he momo rahinga ā-tinana kotahi. Pērā anō hoki mō te pūngao nekeneke, te pūngao pūmanawa ā-papa, me te mahi.
Kia mōhio : He maha ngā rahinga ā-tinana, ahakoa he rite ngā rahinga me ngā waeine, kāore i te rite te rahinga. Hei tauira, te taipana me te mahi. Ko te tātai mō te taipana = te kaha (kg m/s 2 ) x te ringa o te kaha (mita) nō reira ko te waeine ā-ao ko Kg m 2 /s 2. He rite te waeine o te taipana ki te waeine o te mahi, te pūngao rānei, engari kāore te taipana e whakauru ana i te pūngao.
