Translational ka noi

He aha mea he e holumua ai neʻeʻana? School puke maopopo hālāwai mai a hiki i keia ninau: ka mea i alakai mai noi o ke kino (Palapala aie, he maikaʻi mea - "loa paa ke kino" -! ATT, devoid o kekahi ano ua hiki no e ino) - ia mea he holo ma i pololei kekahi laina e holo pololei i koe i loko o ka pau ana i loko o ke kino (ATT) ia laua i kona wahi iho.

Pane manao e e exhaustive. ua haawiia mai Definition, a ma luna o ka papahana ma ka lokomaikai o translational noi kinematics. Initially, keia mea i ka simplest ina o kaʻaʻahu rectilinear noi, alaila, - (! A hou pololei laina) ka oi luna 'a me ka hoihoi' no ka ninau naau ravnoperemennoe ana, he vivid mamuli o i mea no ka noa haule ana o ke kino. Ma lalo o keia pauku, i ka haumāna i ike me ka hoihoi 'lauana, nō like penei:

1. Ke ala hele ma ke kino no ka mea i hahai ana ka mea mamuli o kekahi ʻanuʻu e pili pū ana me na mika pāhoʻonui lua o ka helu maoli: 1: 4: 9: 16 ...

a me ka

2. aoao kaahele aku la oia kino iloko o ka mea i hahai ana ka mea mamuli o kekahi like manawaʻanuʻu, e correlated like me ka moʻo o ōlaʻi nui: 1: 3: 5, 9 ...

Ma ka hoʻoponopono pilikia ana i loko o ke koi 'ia methodological a me ka makemakika hana, he hana hoihoi iaoia o reversibility o ke noi, ma a pau o ka hope loa ikepili i ka loiloi mua a me ka hope versa (ana e like me ka mea ia lŘlŘ ma ke ku pono ana i kuhikuhi, a me ka countdown). Keʻano o ka inverse o ka instantaneous māmā holo maʻi lele o ke kaʻina hana ma nā kumu o ka pololei he ala hoʻololi kona kuhikuhi ana ua hoʻololiʻia mea wale i ka olelo o ka hoʻonui maʻi lele, genetically pili i ka maʻi lele resultant o nā mea a pau i ke kaua noi i ke kino.

Ka "ʻano o ka laina noi" like hoʻi me kinematics, he priori hoʻohuʻu i ka neʻeʻana o ke kino o ka pololei e holumua ai, me ka huli a puni i kekahi (axis) a me ke kanana nei ua. He no ka mea, o keia mālama '-i hoakaka ia aku ana ke ke malama ole i ka nui o ke kino i loko o ka hana, e noonoo pono i kahi maikaʻi mea - i ka meaʻoi (HI) i spatially coincident i ka piko o ka umekaumaha (CG) o ke kino. Eia naʻe, HI hale mua komo i loko o ka "Kinematics" no ka hihia ma kahi o ka nui o ke kino hiki ke malama ole hoohalikeia me ke alanui lōʻihi.

Mālama kānāwai i loko o ka hihia o rectilinear noi i noʻonoʻo ma lalo o aku ana ia mākou (i ole ia, ina e manaoia reciprocal hou 'ana o ka rotational neʻeʻana i loko o ka ikaika o ka ikaika o ke noi ana i mua, a ke hoʻololi) Hōʻuluʻulu mai ka hiki kuapo ana o ke kino ma ka kau i ka holumua ai neʻe

Ma pōkole, ke kumuhana i loko o ke kula ke kālaikūlohea papa neʻeʻana ( 'aneʻane paʻa poe i kūikawā hihia o ke noi a pololei ka laina!) Ua hoakaka nui ai no ka manaʻo a me kaʻimi naʻauao noiʻi. Oe hiki ole ke olelo e pili ana i ka mana loa o ka kula papa i Pilikanaka ka holumua ai neʻeʻana. Qualitative mana AUOO mea wale nalo ma ka hapanui o nā lumi papa.

ʻO kekahi kūikawā hihia o kona alo iho noi ua? Anoee ka hapanui ma ka kumumanaʻo. Oiaio, i ka liʻiliʻi, mīkini Atwood cumbersome a koke incapacitated inquisitive nā haumāna, ua paʻa hoʻouka kekahi ma kahi e ma kaʻaoʻao mamao o ke kālaikūlohea Aha Kuhina. H ÷ ike huahelu e like me ka hāʻuleʻana ma ka uea aole i lalau mai ukana loa meaningless, no ka mea, nānā me ka pakiko-kupono ma ka hihia o rectilinear noi, i mea ole'ālike i ka translational noi i loko o ka mau hihia. He aha laila, ke waiho aku? Wale noiʻi huli i loko o ka puni aku o ka lanakila ma kela aoao o ke kālaikūlohea keʻena hoʻokolohua hoʻohana maoliʻia!

Kipakuʻia kekahi puke laʻana o ka Ferris huila ( "diabolo ka huila e pili ana"), i ka Park, a kona mau huila hana i ka rotational neʻeʻana, a me nā kilo la i hale kamala e neʻe steadily (! Albeit i loko o ka kaiapili) e hoike mai i ka mea e holumua ai neʻeʻana ATT (a me ka hola - ka maoli kino) hiki e ole wale straightforward, akā, no hoi e ana i kekahi uma alanui (i loko o keia hihia typology coincides me ke ala o ka rotational neʻeʻana o ke HI).

I ka manaʻo o ka loaa hihia o ka holumua ai neʻeʻana ma luna o ka peku (ma ka mana 'ano a me ka ole i kaʻimi naʻauao loulou) "waiho ma kahi e kokoke" me ka "Ferris huila". A hiki i ka peku, mākou e e hiki ke nānā paha ke koe ia laua i iho pololei (simulated e kekahi twig a lahilahi lath) o ke kino noi ma luna o nā mea a pau ano o nā poʻohiwi o, roundabouts a me simulators. Ua Ua maopopo ia ma laila e e holumua ai ke ole ka noa haule ana o ka mea ola kino, haehae ae la i kekahi "pii maoli".

E hoolilo ana iʻoiaʻiʻo i ka maemae translational ana ua loa pinepine i loaʻa ma ka 'ano like me ka kūikawā hihia - na degere he laina noi, ua ho'ā-heartedly ke hoomau aku i kaʻimi naʻauao nā o ke kula puke.
