Kufamba kwemahara kwemwaka wechando - matambudziko nemhinduro
1. Dombo rinodonha zvakasununguka kubva pakakwirira kwemamita makumi mana nemashanu. Kana kukurumidza nekuda kwegiravhiti iri 10 ms-2, dombo rinomhanya zvakadii kana rikarova pasi?
Zvinozivikanwa:
Kureba (h) = mamita mashanu
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2
Zvaidiwa: Kumhanya kwekupedzisira kwedombo parinorova pasi (vt)
Kufambisa kupisa - matambudziko nemhinduro
1. Simbi mbiri dzine saizi imwe chete asi dzakasiyana. Kufambiswa kwemafuta eP = kaviri kupfuura kufambiswa kwemafuta eQ. Chii chinonzi tembiricha pakati pesimbi mbiri idzi, sezvakaratidzwa mumufananidzo uri pazasi.
Zvinozivikanwa:
kQ = k
kP = 2k
Kuda: Kupisa pakati pesimbi mbiri
Kufamba kwese kwese - matambudziko nemhinduro
Torque
1. Danda rakareba masendimita 140. Pane masimba matatu anoitwa padanda, F1 = 20 N, F2 = 10 N, uye F3 = 40 N ine gwara nenzvimbo sezvakaratidzwa mumufananidzo uri pazasi. Chii chinonzi torsion chinokonzera kuti danda ritenderere pakati pehukuru hwedanda?
Zvinozivikanwa:
Pakati pehukuru pacho panowanikwa pakati pedanda.
Minda yemagetsi - matambudziko nemhinduro
1. Poindi A iri pakati pemachaji maviri. Machaji ese ari maviri ane hukuru hwakafanana asi chiratidzo chakatarisana uye akaparadzaniswa nedaro re a. Hukuru hwesimba remagetsi panzvimbo A i36 N/C. Kana poindi A ichifamba ne 1/2a pedyo nechimwe chezvose zviri zviviri mhosva, hukuru hwei hwe munda wemagetsi padanho A?
Zvinozivikanwa:
murandu 1 (q)1) = +Q
murandu 2 (q)2) = -Q
Daro riri pakati pekuchaja 1 nepoindi A (r1A) = ½ a
Simba remagetsi - matambudziko nemhinduro
1. Tatu mhosva sezvakaratidzwa mumufananidzo uri pazasiChii chinonzi simba remagetsi akasangana nemhosva B. k = 9 x 109 Nm2C-2, 1 μC = 10-6 C.
Zvinozivikanwa:
qA = 10 µC = 10 x 10-6 C = zana-5 Coulomb
qB = 10 µC = 10 x 10-6 = 10-5 Coulomb
qC = 20 µC = 20 x 10-6 = 2 x gumi-5 Coulomb
Magetsi asingachinji - matambudziko nemhinduro
Simba remagetsi
1. Poindi A mune munda wemagetsiHukuru hwesimba remagetsi panzvimbo A = 0.5 NC-1Kana 0.25-C chaji yakaiswa panzvimbo A, saka chii chinonzi simba remagetsi akashandisa mhosva yacho.
Zvinozivikanwa:
Munda wemagetsi panzvimbo A = 0.5 NC-1
Kuchaja kwemagetsi panzvimbo A = 0.25 C
Kuda: Simba remagetsi
Mitemo yaNewton yekufamba - matambudziko nemhinduro Mutemo wekutanga waNewton wekufamba 1. Kana pasina simba remagetsi rinoshanda pachinhu, saka: (1) chinhu hachina kukurumidza (2) chinhu chiri pachigaro (3) kuchinja kwekukurumidza kwechinhu = 0 (4) chinhu hachigone kufamba nekufamba kwakasimba Izvo … Read more
Kufamba kwemutsetse - matambudziko nemhinduro 1. Girafu yekumhanya (v) vs. nguva (t) inoratidzwa mumufananidzo uri pazasi. Chii chinonzi kuderera kwedanho zvichienderana negirafu. Mhinduro AB = kufamba pakumhanya kusingachinji, BC = kufamba pakumhanya kusingachinji, CD = kufamba pakudzika kusingachinji. 2. Girafu yekufamba kusingachinji inoratidzwa mumufananidzo … Read more
Mutemo waHooke nekusimbaradza - matambudziko nemhinduro Kuchinja kwehurefu 1. Tsvimbo ine hurefu hweL, inodhonzwa nesimba reF. Huwandu hwekureba i ∆L. Chii chinonzi hukuru hwesimba kana kuchinja kwehurefu kuri 4∆L. Inozivikanwa : Simba 1 (F1) = F Kuchinja … Read more
Simba repakati nepakati - matambudziko nemhinduro 1. Bhora remagiramu 200, rakabatanidzwa kumagumo etambo, rinotenderedzwa mudenderedzwa rakatwasuka rine kumhanya kwekona kwe5 rad s-1. Kana kureba kwetambo kuri 60 cm, simba repakati nepakati chii? Rinozivikanwa: Huremu hwechinhu (m) = 200 gr = 200/1000 kg = 2/10 … Read more
