Inertia

Anter

• Nā ʻano inertia
• Kānāwai mua o Newton
• Nā laʻana o ka inertia i ke ola o kēlā me kēia lā

Ua ʻike mākou āpau i nā manawa inā holo mākou ʻoiai e kū ana ma ke kaʻa ʻōpala a haki koke ia, ke hoʻomau nei ke kino e "hoʻomau i ka huakaʻi", kahi e hoʻoikaika ai iā mākou e kiʻi koke i kahi mea paʻa i loko o ke kaʻa i hāʻule ʻole.

Hana ʻia kēia no ka mālama ʻana o nā kino i ko lākou mokuʻāina, hoʻomaha a i ʻole ka neʻe ʻana, ke ʻole lākou e hoʻokau ʻia i ka hana a ka ikaika. ʻIke ka Physics i kēia hanana ʻo "inertia".

ʻO ka inertia ʻO ia ke kūʻē e kūʻē i ka mea i hoʻololi i kona mokuʻāina o ka hoʻomaha a i ʻole ka neʻe ʻana, a hoʻololi wale ʻia kēlā mokuʻāina inā hana ka ikaika iā lākou. Ua ʻōlelo ʻia he nui aku ka inertia o ke kino i ke kūpaʻa ʻoi aku ka nui i kūʻē ʻia e hoʻololi i kona mokuʻāina.

Nā ʻano inertia

Hoʻomaopopo ka Physics ma waena o ka inertia mechanical a me ka inertia pumehana:

• Inertia mīkini. Aia ia i ka nui o ka palaoa. ʻO ka nui o ka nui o ke kino, ʻo ka nui o ka inertia.
• Inertia wela.Hoʻomaopopo ia i ka paʻakikī a ke kino e hoʻololi ai i kona mahana ke hele a hui me nā kino ʻē aʻe a i ʻole ke wela ʻia. ʻO ka inertia wela e pili ana i ka nui o ka nui, conductivity waiwela, a me ka hiki i ka wela. ʻO ka nui o ke kino, ka liʻiliʻi o ka conductivity thermal i loaʻa iā ia a i ʻole ka nui o ka wela i loaʻa iā ia, ʻoi aku ka nui o ka inertia thermal.

Kānāwai mua o Newton

ʻO ka manaʻo o ka inertia i loko o ke kānāwai mua o Newton a i ʻole ke kānāwai o ka inertia, e like me ia inā ʻaʻole pili ke kino i ka hana a nā koa, e hoʻomau ia i ka wikiwiki a me ke kuhikuhi i nā manawa āpau.

Eia nō naʻe, hoihoi e hoʻomaopopo ma mua o Newton, ua hāpai aʻe ka mea ʻepekema ʻo Galileo Galilei i kēia manaʻo ma ke kūʻē ʻana i ka manaʻo o ka Aristotelian i kāna hana.Nā kamaʻilio ma nā ʻōnaehana nui ʻelua o ka honua, ʻo Ptolemaic a me Copernican, mai ka makahiki 1632.

Ma laila ʻo ia i ʻōlelo ai (i ka waha o kekahi o kāna mau huapalapala) inā e heʻe ke kino ma kahi mokulele a poli maikaʻi ʻia, e mālama ia i kāna neʻead infinitum. Akā inā e paheʻe kēia kino ma kahi ʻūlili, e ʻeha ia i ka hana a ka ikaika e hiki ai iā ia ke hoʻolalelale a i ʻole decelerate (kaukaʻi ʻia i ka ʻaoʻao o ka ʻūlili).

No laila ua ʻike ʻo Galileo i ke kūlana kūlohelohe o nā mea ʻaʻole ia he hoʻomaha wale nō, akā ʻo kahi o ka neʻe ʻana a me ka neʻe ʻana o ka lole, inā ʻaʻole he mau pūʻali koa ʻē aʻe e hana ana.

• E nānā pū kekahi: Ke kānāwai ʻelua ʻo Newton

Pili me kēia manaʻo kino, i ka wehewehe ʻana i nā lawena kanaka, ʻike ʻia ka manaʻo ʻē aʻe o ka manawa inertia, i pili ʻia i kēlā mau hihia kahi e hana ʻole ai ka poʻe i kekahi mea ma muli o ka molowa, pili i ka hana maʻamau, hōʻoluʻolu a i ʻole ka waiho wale ʻana iā lākou iho. e like me lākou, ʻo ka mea maʻalahi pinepine.

Nā laʻana o ka inertia i ke ola o kēlā me kēia lā

Nui nā kūlana o kēlā me kēia lā no ka hanana kino o ka inersia:

1. Nā kāʻei noho kū ʻole. Laka wale lākou inā hoʻomau ke neʻe o ke kino ke kū koke.
2. Mīkini holoi me ka milo. He mau puka liʻiliʻi ko ka pahu mīkini holoi no laila ke wili nei e wili i nā lole, e mau ana nā kulu wai i loaʻa ka wikiwiki a me ke kuhikuhi i kā lākou neʻe ʻana a hele i waena o nā lua. ʻLelo ʻia ia manawa ʻo ka inertia o nā kulu, ke kūlana o ka neʻe ʻana i loaʻa iā lākou, kōkua i ka lawe ʻana i ka wai mai nā lole.
3. Ke hopu ʻana i ka kinipōpō i ka soccer.Inā ʻaʻole kū ka mea pana pua me kona mau lima i ka pōpō i noi ʻia e ka mea hahau o ka hui kūʻē, e loaʻa kahi pahuhopu. ʻO ka kinipōpō e neʻe nei, ma muli o kāna inertia, e hoʻomau i ka huakaʻi i loko o ka pahuhopu ke ʻole ka ikaika, nā lima o ka mea kiaʻi i kēia hihia, e ālai iā ia.
4. Holo kaʻa paikikala. Hiki iā mākou ke holomua me kā mākou paikikala i mau mika ma hope o ka hehi ʻana a hooki i ka hana ʻana iā ia, hana mua ka inertia iā mākou a hiki i ka hala ʻana o ka hakakā a i ʻole ke kūpikipiki, a laila kū ke kaʻa uila.
5. Hōʻike hua moa paʻakikī.Inā he hua ko mākou i loko o ka pahu hau a ʻaʻole maopopo iā mākou inā he maka a kuke paha ia, hoʻomaha mākou i ka pā, huli mākou ia mea me ka manamana lima a hoʻāʻo mākou e hoʻokū iā ia: e kū koke ka hua moa i paila ʻia no ka mea paʻa kona ʻikepili a hana a holoʻokoʻa me ka pūpū, no laila inā kū ʻoe i ka pūpū, pēlā nō ka loko. Eia nō naʻe, inā maka ka hua, ʻaʻole paʻa ka wai o loko me ka pū, akā e hoʻomau no ka neʻe no kekahi manawa ʻoi loa ma muli o ka inertia.
6. Wehe i kahi papa haka a waiho i ka mea i luna e waiho ana ma ka papa, ma kahi like. Kahi hana kilokilo kilokilo e pili ana i ka inertia; e kiʻi pono pono ʻoe e huki i ka pākaukau i lalo a ʻoi aku ka māmā o ka mea. ʻO ka mea e kau ana ma ka papa ʻaina e kūʻē i ka hoʻololi o ke ʻano o ka neʻe ʻana, hoʻomau ia e noho mālie.
7. ʻO nā pana me ka hopena i nā pila a i ʻole ka loko wai. Ke hoʻāʻo nei e hoʻokō i nā caroms, ke hoʻohana pono nei i ka inertia o nā kinipōpō.
