ʻAʻole ka ikaika conservative ka inoa o kahi ikaika, e like me ke umekaumaha, ka friction, a pēlā aku. Hōʻike ka ikaika conservative i ke ʻano o kahi ikaika. Inā like ka hana holoʻokoʻa i hana ʻia e kahi ikaika ma luna o kahi mea, i ka wā e neʻe ai ka mea mai kona kūlana mua a hiki i ka hoʻi ʻana o ka mea i kona kūlana mua, me ka ʻole, a laila he ikaika conservative ka ikaika. Ua ʻōlelo ʻia he ikaika conservative inā ʻaʻole hilinaʻi ka hana i hana ʻia e ka ikaika ma luna o kahi mea i ke ala e hele ai ka mea akā ma ka loli wale nō i kona mau kūlana mua a me hope.
No ke aha i anuanu ai ka makani?
No ke aha i anuanu ai ka makani? Ua nīnau anei ʻoe i kekahi mea e like me kēia.
Inā ʻoe e wela loa ana 😀 a pā koke mai ka makani mālie, ua hou kou kino. ʻO ka maʻamau, ua anuanu ka makani. Ua ʻike paha ʻoe i kahi makani wela? 😉 Hiki i ka ea ke wela a anuanu paha, akā, he anuanu a anuanu paha ka makani. No ke aha i anuanu ai ka makani?
ʻO ka makani ka ea e neʻe ana ma muli o nā ʻokoʻa o ke kaomi ea . Hiki ke hana ʻia ka makani e ka wili ʻana o ka Honua, akā ʻaʻole i kūkākūkā ʻia kēia ma kēia ʻatikala. Neʻe pinepine ka makani mai nā wahi o ke kaomi ea kiʻekiʻe i nā wahi o ke kaomi ea haʻahaʻa. Pili ke kaomi ea i ka nui o ka ea a i ʻole ke kaumaha . Ma ke kiʻekiʻe like, ʻoi aku ka nui o ke kaomi o ka ea me ka nui a i ʻole ke kaumaha. I ka ʻaoʻao ʻē aʻe, ʻoi aku ka liʻiliʻi o ke kaomi o ka ea me ka nui a i ʻole ke kaumaha.

E ʻoluʻolu e nānā i kekahi o nā mea a puni ʻoe. Inā ʻoe e luku i kahi mea, no ka laʻana he pōhaku, e māhele ka pōhaku i kekahi mau ʻāpana liʻiliʻi. Inā e kuʻi hou ʻia ka pōhaku, e lilo ka pōhaku i mau ʻāpana liʻiliʻi. Pehea inā e kuʻi hou ʻia nā ʻāpana pōhaku? ʻOiaʻiʻo, ua kuʻi ʻia nā ʻāpana pōhaku a lilo i mau ʻāpana liʻiliʻi. Hiki ke māhele ʻia nā pōhaku i mau ʻāpana liʻiliʻi a hiki i ka pau ʻole? Hōʻike ka ʻoiaʻiʻo inā e māhele ʻia kekahi mea i mau ʻāpana liʻiliʻi e hiki i kahi e hiki ʻole ai ke māhele ʻia ka ʻāpana liʻiliʻi o ka mea i mau ʻāpana liʻiliʻi. ʻO ka ʻāpana liʻiliʻi loa o kahi mea hiki ʻole ke māhele hou ʻia ua kapa ʻia ʻo ia he ʻātoma. No laila, ʻo ka ʻātoma ka ʻāpana liʻiliʻi loa o kēlā me kēia mea o ke ao holoʻokoʻa.
Nā Kānāwai o Newton
ʻEkolu nā kānāwai o ka neʻe ʻana o Newton, ʻo ia hoʻi ke kānāwai mua o Newton, ke kānāwai ʻelua o Newton, a me ke kānāwai ʻekolu o Newton.
Ke Kānāwai Mua o Newton
ʻŌlelo ke Kānāwai Mua o Newton e noho mālie ana kēlā me kēia mea e neʻe ana ma kahi laina pololei ma ka wikiwiki mau inā ʻaʻohe ka ikaika holoʻokoʻa e hana ana ma luna o ka mea.
Ka ikaika haʻalulu
ʻO ka haʻalulu kahi ikaika e kāohi ana i ka neʻe ʻana o kahi mea. Hana kēia ikaika ma waena o nā ʻili e pili ana. Ma kēia kumuhana, pili ka haʻalulu i aʻo ʻia i ka ikaika e hana ana ma waena o ʻelua mau ʻili paʻa e pili ana, e like me ka haʻalulu ma waena o ke kumu o kahi poloka a me ka papahele, ka haʻalulu ma waena o ke kapuaʻi o kahi kāmaʻa a me ka papahele, a i ʻole ka haʻalulu ma waena o ka huila kaʻa a me ke alanui.
Ka Momentum a me ka Impulse
Ka ikaika laina
Ua wehewehe ʻia ka momentum linear a i ʻole ka momentum maʻamau e like me ka huahana o ka nuipa a me ka wikiwiki.
p = mv
Wehewehe: p = momentum, m = mass (kilokala), v = speed (mika/kekona)
He nui vector ka Momentum no laila ma waho aʻe o ka nui, loaʻa pū kekahi kuhikuhi o ka momentum. Ua like ke kuhikuhi o ka momentum me ke kuhikuhi o ka wikiwiki o ka mea a i ʻole ke kuhikuhi o ka neʻe ʻana o ka mea.
Ke kānāwai o ka mālama ʻana i ka ikehu mechanical
ʻŌlelo ke kumumanaʻo ikehu hana-kinetic ʻo ka hana holoʻokoʻa, a i ʻole ka hoʻoikaika ʻana i hana ʻia e ka ikaika upena ma luna o kahi mea, ua like ia me ka loli o ka ikehu kinetic o ka mea. Inā hana ka ikaika upena i ka hana maikaʻi (aia ka ikaika upena ma ke kuhikuhi like me ka neʻe ʻana), a laila piʻi ka ikehu kinetic o ka mea. I ka ʻaoʻao ʻē aʻe, inā hana ka ikaika upena i ka hana maikaʻi ʻole (aia ka ikaika upena ma ke kuhikuhi ʻē aʻe i ka neʻe ʻana), a laila emi ka ikehu kinetic o ka mea.
Ka hoʻoikaika a me ka ikaika
Inā ʻoe e paʻi i kahi puke ma luna o kahi papaʻaina a hiki i ka neʻe ʻana, ke hana nei ʻoe i ka hana ma luna o ka puke. Inā hāʻule kahi mea i luna o ka honua no ka mea ua huki ʻia e ka ikaika o ke koʻikoʻi, a laila hana ka ikaika o ke koʻikoʻi ma luna o ka mea. I ka ʻaoʻao ʻē aʻe, inā ʻoe e paʻi i kahi mea me kou ikaika a pau a pulu ʻoe i ka hou akā ʻaʻole neʻe ka mea, a laila ʻaʻole ʻoe i hana i ka hana ma luna o ka mea. I ke ola o kēlā me kēia lā, ʻōlelo kekahi poʻe ua hana ʻoe i ka hana a i ʻole ua hana nui ʻoe e paʻi i ka mea, akā e like me ke ʻano o ka physics , ʻaʻole ʻoe i hana i ka hana ma luna o ka mea no ka mea ʻaʻole i ʻike ka mea i ka neʻe ʻana.
Neʻe pōʻai like
I ko kākou ola o kēlā me kēia lā, pinepine kākou e hālāwai me nā mea e neʻe ana i kahi neʻe pōʻai. ʻO kahi laʻana o kahi mea e neʻe ana i kahi neʻe pōʻai ʻo ia ka lima kekona, ka lima minuke, a me ka lima hola ma kahi uaki analog. Hele mau ka lima kekona i kahi kihi o 360 ° i loko o 60 kekona (hoʻokahi minuke) a i ʻole kahi kihi o 6 ° i hoʻokahi kekona. Hele mau ka lima minuke i kahi kihi o 360 ° i loko o 60 mau minuke (hoʻokahi hola) a i ʻole kahi kihi o 6 ° i hoʻokahi minuke. Hele mau nō hoʻi ka lima hola i kahi kihi o 360 ° i loko o 24 mau hola (hoʻokahi lā). Inā neʻe mau kahi mea i kahi neʻe pōʻai, e like me ka lima kekona, ka lima minuke, a i ʻole ka lima hola, a laila ua ʻōlelo ʻia kēia mau mea e hana ana i kahi neʻe pōʻai like . Hiki iā ʻoe ke inoa i kahi laʻana o kahi neʻe pōʻai maʻamau āu i ʻike ai a i ʻole i noʻonoʻo ai?
Ke Kānāwai o Hooke
Inā ʻoe e hoʻolōʻihi i kahi kaula laholio a i ʻole kahi huila laholio i kahi kiko, e hoʻolōʻihi ia. Ma hope o kou hoʻokuʻu ʻana i ke kaumaha, e hoʻi ka laholio i kona lōʻihi mua. Pēlā nō, ke hoʻolōʻihi ʻoe i kahi pūnāwai, e hoʻolōʻihi ia. Ma hope o kou hoʻokuʻu ʻana, e hoʻi ia i kona lōʻihi mua. E hoʻolōʻihi kahi pūnāwai a laholio paha i ka wā e hoʻolōʻihi ʻia ai a e hoʻi i kona lōʻihi mua ma hope o ka hoʻokuʻu ʻia ʻana o ke kaumaha no ka mea he elastic ia. ʻO ka elasticity ka hiki o kahi mea ke hoʻi i kona ʻano mua ke wehe ʻia ka ikaika i hoʻopili ʻia iā ia.
