Tsanangudzo ye capacitor yeplate yakafanana

Parallel plate capacitor i capacitor ine maplate maviri e conductor akaenzana, plate imwe neimwe ine nzvimbo yakaenzana (A) uye maplate maviri akaparadzaniswa nedaro rakati (d), sezvakaratidzwa mumufananidzo uri kuruboshwe. Rimwe remaplate e conductor rakachajwa zvakanaka (+Q) nepo rimwe plate re conductor rakachajwa zvakaipa (-Q), uko huwandu hwe electric charge paplate yega yega yakaenzana. Kuti chaji isafambe ichienda kumorekuru yemhepo, capacitor inoparadzaniswa nenharaunda, uye pakati peplate mbiri, pane vacuum.

Nyaya inotaura nezve Mutemo waKepler

Uchiri kurangarira here ndangariro dzekutanga kutasva mota? Kana uri mumotokari inofamba, unoona sekunge muti kana chivakwa chiri kufamba. Panguva iyoyo, ungafunga kuti miti kana zvivakwa zviri kufamba, iwe nemotokari makazorora. Kutaura zvazviri, iwe nemotokari munofamba, miti kana zvivakwa zvichizorora. Chiitiko ichi chekufamba kwenhema chinoitika zuva nezuva. Mangwanani ega ega, "zuva rinobuda" kumabvazuva kwedenga robva raenda kumadokero robva "ranyura" kumadokero kwedenga masikati.

Saizvozvowo, husiku, unowanzoona mwedzi uchifamba kubva kumabvazuva uchienda kumadokero. Wakambofunga here kana kufungidzira kuti zuva nemwedzi zvaifamba-famba pasi rose, nyika ichizorora?

Chinyorwa pamusoro peMoment of Force

1. Ruoko rwechirevereri

Ongorora chinhu chinotenderera, senge gonhi rekamuri. Kana gonhi rakavhurwa kana kuvharwa, gonhi rinotenderera. Mahinji anobatanidza gonhi nemadziro anoshanda sechikamu chekutenderera.

Mufananidzo wemusuwo unoonekwa kubva kumusoro. Ongorora muenzaniso apo musuwo unosundwa mumasimba maviri akafanana ane hukuru negwara rakafanana, uko gwara resimba rakanangana nemusuwo. Pakutanga, musuwo unosundwa nesimba reF₁,r₁ kubva pachikamu chekutenderera. Zvadaro, gonhi rinosundirwa nesimba reF₂,r₂ kure nechikamu chekutenderera. Kunyange zvazvo hukuru negwara resimba F₁ =F₂, simba raF₂ zvinoita kuti gonhi ritenderere nekukurumidza kupfuura simba raF₁Nemamwe mashoko, simba raF₂ zvinokonzera kukurumidza kukuru kwekona zvichienzaniswa nesimba raF₁Unogona kuratidza izvi.

Nyaya pamusoro pemutemo wechipiri waNewton wekufamba kwese kwese

4.1 Hukama huripo pakati penguva yesimba, nguva yekusaita chinhu, uye kukurumidza kwekona

Kana paine simba rinobuda (ΣF) richishanda pachinhu chine huremu (m) chinhu chinofamba nenzira yakatwasuka nekuwedzera (a). Hukama huripo pakati pesimba rinobuda, huremu, uye kuwedzera hunoratidzwa ne equation:

Σ F = ma

Uyu ndiwo muenzanisiro wemutemo wechipiri waNewton.

Huwandu hwekufamba kwekutenderera kwakafanana nesimba rinobuda (ΣF) mukufamba kwakatwasuka ndiyo nguva yesimba rinobuda (Στ). Huwandu hwekufamba kwekutenderera kwakafanana nehukuru (m) mukufamba kwakatwasuka ndiyo nguva dzekusaita (I). Huwandu hwekufamba kwekutenderera kwakafanana nekuwedzera simba (a) mukufamba kwakatwasuka ndiyo angular acceleration (α).

Muviri wakasimba unoumbwa nezvidimbu zvakawanda; saka, simba rekukwevera rinoshanda pane chimwe nechimwe chezvidimbu izvi. Nemamwe mashoko, chidimbu chimwe nechimwe chine huremu hwacho. Pakati pesimba rekukwevera chinhu ipo pachinhu apo huremu hwezvikamu zvese zvechinhu hunoonekwa sehwakaiswa pakati ipapo.

Chinyorwa pamusoro peMhando dzekuenzana kwe muviri wakaoma

Hazvisi zvinhu zvese zvatinowana muhupenyu hwezuva nezuva zvinogara zvichizorora. Pamwe pakutanga chinhu chinozorora, asi kana chikafambiswa (semuenzaniso nemhepo) zvinhu zvinogona kufamba. Dambudziko nderekuti, kana mushure mekufamba, zvinhu zvinodzokera panzvimbo yazvo yekutanga kana kwete. Izvi zvinoenderana nerudzi rwekuenzana kwechinhu. Mushure mekufamba, pachava nemikana mitatu, inoti:

(1) chinhu chinodzokera panzvimbo yacho yekutanga,

(2) chinhu chinobva panzvimbo yacho yepakutanga,

(3) chinhu chinoramba chiri panzvimbo yacho itsva.

Chinyorwa pamusoro pekuenzana kwemuviri wakasimba

1. Chimiro chekutanga

Mutemo Wechipiri waNewton unoti kana simba rinobuda pachinhu (chinhu chinoonekwa sechikamu chimwe chete) risiri zero,

ipapo chinhu chichafamba nekukurumidzisa nguva dzose, uko kutungamira kwekufamba kwechinhu = kutungamira kwesimba rose. Kana simba rinobuda riri zero, zvinoreva kuti chinhu chacho chiri pazororo kana kuti chichifamba nekumhanya kunogara kuripo.

ΣF = ma

Kana chinhu chakamira kana kuti chichifamba nekumhanya kwakafanana, chinhu chacho hachina acceleration (a). Nekuti acceleration (a) = 0, equation iri pamusoro inoshanduka kuita:

Chinyorwa pamusoro pe Zvitubu zvakatevedzana uye zvakafanana

1. Zvitubu zvakatevedzana

Kana chitubu chakabatana zvakatevedzana, sezviri pamufananidzo uri padivi, saka:

1. Kuwedzera kwehurefu hwechitubu = kuwedzera kwehurefu 1 + kuwedzera kwehurefu 2

Δ y = Δ y ₁ + Δ y ₁

2. Simba rinoonekwa nechitubu chakaenzana = simba rinoonekwa nechitubu 1 = simba rinoonekwa nechitubu 2

F _s = F ₁ = F ₂

1. Mutemo waHooke wezvitubu

Kana chitubu chikadhonzwa kurudyi, chitubu chinotambanuka uye chinowedzera kureba (mufananidzo 1). Kana simba rekudhonza risiri guru, zvinowanikwa kuti kuwedzera kwehurefu hwechitubu (Δx) kunoenderana nehukuru hwesimba rekudhonza (F). Nemamwe mashoko, simba rekudhonza rakakura, kureba kwechitubu kunowedzerawo. Kuenzanisa hukuru hwesimba rekudhonza (F) nekuwedzera kwehurefu hwechitubu (Δx) kunogara kuripo.

Tsanangudzo yemutemo weOhm

Munenge mune zvese zvinofambisa simbi, simba remagetsi rinoenderana nehuwandu hwemagetsi, uko chiyero chesimba remagetsi nehuwandu hwemagetsi chinoramba chiripo. Zvinoratidzwa nemasvomhu kuburikidza ne equation:

ρ = E / J

E = munda wemagetsi , ρ = resistivity , J = density yemazuva ano

Iyo ρ inogara ichishandiswa inonzi resistivity, iyo kukosha kwayo kunogara kuripo uye haitsamiri pamunda wemagetsi unoburitsa magetsi.
