Chimiro chekutanga chekuenzana kwemuviri wakasimba :
Mutemo weChipiri waNewton unoti kana simba rinobuda richishanda pachinhu (chinhu chacho chinoonekwa sechimedu) risingaenzane ne zero, chinhu ichocho chichafamba nekukurumidzisa nguva dzose uko gwara rekufamba kwechinhu rakafanana negwara resimba rinobuda. Kana simba rinobuda riri zero, chinhu chacho chiri pazororo kana kuti chinhu chacho chiri kufamba nekumhanya kusingachinji.
Kana chinhu chikamira kana chichifamba nekumhanya kwakafanana, chinhu chacho hachina kukurumidza (a). Nekuti kukurumidza (a) = 0, equation iri pamusoro inoshanduka kuita:
Iyi equation inogona kupatsanurwa kuita zvikamu zvayo pa x-axis, y-axis uye z-axis.
Kana masimba achishanda munzvimbo yakatwasuka chete, saka equation 1 inoshandiswa. Kana masimba achishanda munzvimbo yakatwasuka chete, saka equation 2 inoshandiswa. Kana masimba achishanda panzvimbo imwe chete (madimension maviri), saka equation 1 ne2 dzinoshandiswa. Kana masimba achishanda munzvimbo imwe chete (madimension matatu), saka equation 1, 2 ne3 dzinoshandiswa.
Simba inhamba yevector, ine hukuru uye gwara. Tichitarisa maCartesian coordinates (x, y, uye z axes) uye zvichienderana nemitemo, kana simba rakafanana ne x-axis iri negative (kuruboshwe) kana simba rakafanana ne y-axis iri negative (pasi), simba racho harina kunaka. Kusiyana neizvi, kana simba rakafanana ne x-axis iri negative (kurudyi) kana simba rakafanana ne y-axis iri negative (kumusoro), simba racho rinenge riri negative.
Muenzaniso 1.
Mashoko ekuwedzera:
F = simba rekukwesha, fg = simba rekukweshana, N = simba rakajairika, w = simba rinokwevera pasi, m = uremu, g = kukurumidza nekuda kwesimba rinokwevera pasi.
Chinhu chiri panzvimbo yakanyarara nekuti huwandu hwemasimba ese ari kushanda pachinhu chacho i zero.
Ongorora simba rega rega riri kushanda pachinhu chacho.
Masimba anoshanda munzira yakatwasuka (x-axis):
Simba rekukwesha (F) uye simba rekukwesha (f)g) dzine hukuru hwakafanana asi dzakatarisana. Kutungamira kwesimba rekudhonza kuri kurudyi kana pamwe chete ne x-axis (simba rakanaka), zvakasiyana, kutungamira kwesimba rekudhonza kuri kuruboshwe kana pamwe chete ne x-axis (chiratidzo chisina kunaka). Nekuti hukuru hwemasimba ese ari maviri hwakafanana (hunomiririrwa nehurefu hwemuseve wakafanana) uye kutungamira kwemasimba ese ari maviri kwakatarisana, huwandu hwemasimba maviri aya hwakaenzana ne zero.
Masimba anoshanda akananga kwakamira (y-axis):
Pachikamu chakamira (y-axis) pane simba rekukweva (w) uye simba rakajairika (N). Kutungamira kwesimba rekukweva kwakatarisana nepakati peNyika kana munzira ye y-axis isina kunaka (simba rine chiratidzo chekunega), nepo simba rakajairika riri munzira ye y-axis yakanaka (simba rine chiratidzo chekunega). Hukuru hwemasimba maviri aya hwakafanana asi mafambiro awo akasiyana, saka masimba maviri aya anokamurana.
Chinhu chiri mumuenzaniso uri pamusoro apa chakazorora nekuti simba rinobuda rinoshanda pachinhu chacho, pamativi akatwasuka nepamativi akatwasuka, rakaenzana ne zero.
Muenzaniso 2.
Simba rinokwevera pasi nemasimba akajairika anoshanda pachinhu ichi hazviratidzwe nekuti zvinodzimana. Kana simba F rikaiswa kumativi ese echinhu sezvakaratidzwa mumufananidzo, hukuru hwemasimba maviri hwakaenzana asi hwakasiyana. Chinhu chacho chicharamba chakamira here?
Kuti zvikubatsire kunzwisisa izvi, isa bhuku patafura. Pakutanga bhuku harina kumira nekuti simba rinobuda mubhuku izero. Tevere, isa simba kumativi ese ebhuku, sezvakaratidzwa mumufananidzo. Kana simba rikashanda kumagumo ebhuku nehukuru negwara sezvakaratidzwa mumufananidzo, izvi zvakafanana nekutenderera bhuku uye zvechokwadi bhuku richatenderera. Bhuku rinotenderera nekuti pane nguva yesimba inokonzerwa nesimba F. Akisi yekutenderera iri pakati pebhuku. Kana pasina simba rekukweshana riri kushanda pachinhu, nguva yesimba inoenderana nehuwandu hwenguva dzesimba rinogadzirwa nemasimba maviri F. Nzira yekutenderera kwechinhu inoenderana newachi kuitira kuti nguva dzese dzesimba dzive dzisina kunaka.
Chimiro chechipiri chekuenzana kwemuviri wakasimba
Zvichibva pamuenzaniso wechipiri uri pamusoro apa, zvinogona kugumiswa kuti kana nguva yesimba rinobuda pachinhu isiri zero (chinhu chinoonekwa sechinhu chakasimba), ipapo chinhu chinotenderera.
Kuti chinhu chisatenderere (chisafambe), simba rinobuda rinofanira kuva zero. Kana chinhu chisiri kutenderera, hachina angular acceleration. Nekuti angular acceleration iri zero, equation iri pamusoro inoshanduka kuita:
Dzidza mienzaniso yezvinetso zvepakati nepakati uye mienzaniso yezvinetso zvepakati nepakati zvemuviri.
