Kumhanya kwekupararira kwemafungu kunogona kutsanangurwa uchishandisa fomura yakajairika:
Tsananguro yefomura:
v = kumhanya kwekuparadzira mafungu (mayuniti imita/sekondi)
T = nguva yemafungu = nguva inodiwa kuti mafungu afambe nehurefu hwewavelength imwe (mayuniti masekondi)
f = frequency = huwandu hwema wavelengths anopfuura poindi imwe chete mukati mesekondi imwe (yuniti yacho i1 / sekondi = hertz)
lambda = kureba kwehurefu (mayuniti mamita)
Fomura iri pamusoro apa inobva kupi? Pamwe unoyeuka fomura yekumhanya v = s / t, apo v = velocity, s = distance travel, uye t = time interval. Iyi ndiyo fomura yekumhanya kwechinhu, sezvakadzidzwa munyaya yekufamba kwemutsara.
Kana zvikagadziriswa kuti zvienderane nekufamba kwemafungu, daro rinofambwa rakafanana nerefurefu rewavelength, nguva inosara yakafanana nenguva (T = 1/f) kana kuti frequency (f = 1/T).
Kumhanya kwekupararira kwemafungu patambo
Mafungu anopararira patambo kana tambo mafungu anochinjika, akaverengerwa achishandisa fomura:
Tsananguro yefomura:
v = kumhanya kwemafungu patambo (mayuniti ari mamita/sekondi)
F = simba rekusunga tambo (mayuniti kg m/s)2 (anozivikanwawo saNewton)
Myu = kuwanda kwetambo = huremu pahurefu hwetambo (mayuniti makirogiramu/mita)
Zvichibva pafomura iri pamusoro apa, zvakagumiswa kuti kumhanya kwemafungu patambo kunoenderana nesimba rekumanikidzwa kwetambo uye huremu hwehurefu hwetambo. Kuti fomura iyi inowanikwa sei kunogona kudzidzwa mukubva kwefomura. kumhanya kwekuparadzira mafungu patambo.
Kumhanya kwemafungu eruzha
Mafungu eruzha mafungu erefu anopararira kuburikidza nenzira dzakasiyana-siyana. Kune nzira dzakawanda dzinogona kufamba nemafungu eruzha, kusanganisira mhepo, mvura, madziro, nezvimwewo. Kumhanya kwekupararira kwemafungu eruzha kunoenderana nechimiro chechinhu chaanofamba nacho, sekumhanya kwekupararira kwemafungu anochinjika mutambo kunoenderana nechimiro chetambo.
Kana mafungu eruzha akafamba nemumvura yakaita semhepo kana mvura, kumhanya kweruzha kunoverengerwa uchishandisa fomura
Tsananguro yefomura:
v = kumhanya kwemafungu eruzha
B = modulus yakawanda
rho = kuwanda
Kana ruzha rukabuda netsvimbo refu, yakasimba, kumhanya kweruzha kunoverengerwa uchishandisa fomura
Tsananguro yefomura:
Y = Modulus yemudiki
Kumhanya kwemafungu emagetsi
Kumhanya kwemafungu emagetsi (kumhanya kwemafungu echiedza) i3,00 x 108 m/s.
Kumhanya kwekupararira kwemafungu patambo
Zvinhu zvinopesvedzera kumhanya kwemafungu anochinjika mutambo
Kumhanya kwemafungu emuchina kunoenderana chete nechimiro chechinhu chaanofamba nacho. Kumhanya kwemafungu egungwa kunoenderana nechimiro chegungwa, kumhanya kwemafungu eruzha kunoenderana nechimiro chemhepo yaanopfuura nayo. Saizvozvowo, kumhanya kwemafungu mutambo kunoenderana nechimiro chetambo. Kuti ujekese izvi, tanga waita bvunzo yekuferefeta zvinhu zvinopesvedzera kumhanya kwemafungu mutambo.
Zvichibva pakuedza kwakaitwa, zvakagumiswa kuti kumhanya kwemafungu patambo kunoenderana nesimba rekumanikidzwa patambo uye huremu hwehurefu hwetambo. Simba rekumanikidzwa patambo rakakura (tambo yakasimba), uye kufamba kwemafungu kunokurumidza. Kusiyana neizvi, huremu hwetambo hwakakura, kufamba kwemafungu kunononoka.
Kutorwa kwefomura yekumhanya kwemafungu anochinjika mutambo
Kuwanikwa kwefomura yekumhanya kwemafungu patambo humbowo hwemasvomhu hwezvinhu zvinopesvedzera kumhanya kwekupararira kwemafungu patambo.
Funga nezvechikamu chemafungu kana kurova kwemoyo kuchifamba kurudyi kuburikidza netambo (mufananidzo wepamusoro). Mufananidzo wekurova kwemoyo wakakura, uchiperekedzwa nemufananidzo wesimba rekumanikidzwa kwetambo F richishanda patambo inopfuura nepamusoro pemafungu (mufananidzo wepazasi).
Simba rega rega rekumanikidzwa kwetambo (F) rinotsanangurwa nenzira yakatwasuka (F)x) uye nzira yakatwasuka (F)yMauto ese ari maviri Fx dzine hukuru hwakafanana uye dzine mativi akasiyana saka dzinodzimana. Pane kudaro kune masimba maviri eFy akananga pakati pedenderedzwa.
Hukuru hwesimba rega rega riri munzira yakatwasuka (F)y):
Simba rinobuda richienda pakati pedenderedzwa
Musangano wevanhu vakawanda
Mutemo wechipiri waNewton wekufamba kwese kwedenderedzwa
Tsananguro yefomura:
v = kumhanya kwemafungu patambo (m/s)
F = simba rekumanikidzwa kwetambo (Newton)
myu = kuwanda kwetambo = huremu pahurefu hwetambo (kg/m)
Zvichibva pa equation iri pamusoro apa, zvinogona kugumiswa kuti kumhanya kwemafungu kunoenderana nekumanikidzwa kwetambo uye kunoenderana nehuremu hwetambo pahuniti imwe neimwe. Saka, kana tambo yakabatana, mafungu anokurumidza, uye huremu hwetambo hwakakura, mafungu anononoka.
