Translational chitsungo

Chii chinonzi mberi sangano? School Bhuku zvakajeka isu inoungana kuti mubvunzo uyu: mberi inofamba muviri (Ona, yakanaka chinhu - "zvachose zvikukutu muviri" -! That, isingambokwanisi mhando zvaiita kuti akaremara) - iri sangano umo chero yakarurama mutsetse wakavhomorwa anoramba newokuti roga panguva yose kufamba mukati muviri (it).

Mhinduro rinoita dzoga. Tsanangudzo anopiwa, uye pamusoro wenyaya vachifarira translational inofamba kinematics. Pakutanga, izvi ndizvo nyore nyaya yunifomu rectilinear inofamba, ipapo - (! Uye zvakare zvachose Linear) zvikuru kunzwisisa uye zvinofadza nokuda kubvunzana pfungwa ravnoperemennoe kufamba, mumwe muenzaniso wakajeka chiri vakasununguka kuwa miviri. Pasi chikamu ichi, mboni yava Aingoziva dzinonakidza mapatani, akataura sezvinotevera:

1. Nzira vakafamba nomuviri pamusoro anotevedzana zvikamu zviri chokuita sezvo dzinoungana zvakasikwa nhamba: 1: 4: 9: 16 ...

uye

2. Nzira zvaiyambuka muviri panguva anotevedzana akaenzana nguva zvikamu, vari correlated sezvo akatevedzana shamisa nhamba: 1: 3: 5, 9 ...

In nekugadzirisa matambudziko kuitika mukati runodiwa methodological uye akarongeka zvishandiso, imwe nzira inonakidza pamusoro reversibility inofamba, umo vose yokupedzisira Data vari kutanga ndiEzekieri (kufamba sezvo kumbowanikwa negwara, pamwe Countdown). The simba pamusoro Ivan Kuchin ari nguva imwe velocity Vector acho panguva dzose dzinokosha yakarurama kuchinja nhungamiro dzaro kuchinja ndiyo chete vatungamirire kumhanyisa Vector, majini chokuita Vector nomuuyo vose vehondo kureva muviri.

The "Dynamics pamusoro Linear inofamba" uyewo kinematics, a priori zvinoratidza kuti sangano muviri ndiwo tisingatauri mberi, pasina Paakatendeuka chero akabatana uye kuoma kwakanga. Imhaka ichi pre-wainyatsotaura zvinhu zvinogona kuregeredzwa kukura muviri ari basa, tichifunga pachinzvimbo akakodzera chinhu - zvinhu pfungwa (MT) vari spatially coincident pamwe musimboti regiravhiti (CG) muviri. Zvisinei, kare MT nzvimbo akapinda mu "Kinematics" tubhokisi apo kukura kwomuviri anogona kuregeredzwa kuenzaniswa gwara pakureba.

Mitemo Conservation kune rectilinear inofamba uyewo kukurukurwa pasi ezvinhu apo isu Abstract kubva zvichibvira kutenderera muviri nokuisa mberi kufamba kwake (aizongoramba kunzi itirana Kushandurwa rotational kufamba mu simba nesimba inofamba pakati mberi uye harungashandurwi)

Muchidimbu, nyaya muchikoro wefizikisi kosi mberi kwebasa (akapotsa kumiririrwa nyaya chaiyo inofamba pamwe achirurama mutsetse!) Anopa wandei zvokudya pfungwa uye yokungotaura tsvakurudzo. Unogona kutaura pamusoro experimental chikamu kosi yechikoro kuti vanodzidza mberi kufamba. Qualitative experimental setup ndechokungoti ndisipo mumakirasi dzakawanda.

Kunyange nyaya chaiye chairuramira mberi inofamba anodzidzwa zvikurukuru dzidziso. Chokwadi, kwete chitoyi, muchina Atwood yainetsa uye nokukurumidza incapacitated kuongorora vadzidzi, vari yakaiswa zvechigarire kumwe kudivi kure wefizikisi cabinet. Kuratidzwa zvidzidzo zvakadai zvishoma nezvishoma mumatope pamwe waya rwakatambanudzwa nhumbi zvachose zvakunoreva, sezvo zvacho andinenge pakuparwa rectilinear inofamba, zvisina kufanana kune translational inofamba iri zvavo nyaya. Chii zvino aigona akakurudzira? Kutsvakurudza chete kutsvaka iri dzakapoteredza chokwadi mhiri wefizikisi rabhoritari vachishandisa rwokuzvarwa zvaiti!

Nemhepo bhuku muenzaniso Ferris vhiri ( "Dhiyabhorosi Wheel '), nomukombero uye ane spokes kuita munhu rotational sangano, uye akataura matumba vari kutamira zvakatsiga (! Kunyange mudenderedzwa) kunotivimbisa kuti kufambira mberi kufamba that (uye anenge - muviri chaiwo) unogona kwete zvakarurama chete, asi kuva chinhu curved nzira (mu iyi typology rinobatana pamwe trajectory pamusoro rotational kwebasa MT).

Pfungwa yokuwana nyaya mberi kufamba pamusoro nhandare (mu experimental rudzi uye kwete yokungotaura nharo) "nhema kumwewo pedyo" ne "Ferris vhiri". Wakati asvika playground, tichakwanisa kuona kuti mapfupa kuenderana inozviitira zvakananga (simulated upi bukira kana mutete lath) muviri inofamba iri ose ndatsamwa, roundabouts uye simulators. Zviri pachena kuti kuchava mberi kutoti wakasununguka kuwa ane muviri zvisina upenyu, akabvarura vamwe "achikwira furemu".

Nechokwadi kuti yakachena translational sangano kakawanda kuwanikwa zvakasikwa ari nyaya inokosha - mberi Linear inofamba, isu kuvheneka-heartedly anogona mberi kune yokungotaura acho ane bhuku chikoro.
