Kufamba kwemahara kwemwaka wechando - matambudziko nemhinduro
1. Dombo rinodonha zvakasununguka kubva pakakwirira kwemamita makumi mana nemashanu. Kana kukwira kwesimba nekuda kwegiravhiti kuri 10 ms -2 , kumhanya kwedombo kana rikarova pasi chii?
Zvinozivikanwa:
Kureba (h) = mamita mashanu
Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s 2
Zvinodiwa: Kumhanya kwekupedzisira kwedombo parinorova pasi (v t )
Kufambisa kupisa - matambudziko nemhinduro
1. Simbi mbiri dzine saizi imwe chete asi dzakasiyana. Kufambiswa kwekupisa kweP = kaviri kupfuura kufambiswa kwekupisa kweQ. Chii chiri tembiricha iri pakati pesimbi mbiri idzi, sezvakaratidzwa mumufananidzo uri pazasi.
Zvinozivikanwa:
k Q = k
k P = 2k
Zvinodiwa: Tembiricha iri pakati pesimbi mbiri
Kufamba kwese kwese - matambudziko nemhinduro
Torque
1. Danda rine urefu hwe 140 cm. Pane masimba matatu anoshandiswa padanda, F 1 = 20 N, F 2 = 10 N, uye F 3 = 40 N ine gwara nenzvimbo sezvakaratidzwa mumufananidzo uri pazasi. Chii chinonzi torque chinoita 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 ne1/2a pedyo neimwe yemachaji ese ari maviri , hukuru hwesimba remagetsi panzvimbo A hwakaita sei?
Zvinozivikanwa:
Mutengo 1 (q 1 ) = +Q
Mutengo wechipiri (q 2 ) = -Q
Daro riri pakati pekuchaja 1 nepoindi A (r 1A ) = ½ a
Simba remagetsi - matambudziko nemhinduro
1. Machaji matatu sezvakaratidzwa mumufananidzo uri pazasi . Chii chinonzi simba remagetsi rinowanikwa nechaji B. k = 9 x 10 9 Nm 2 C −2 , 1 μC = 10 −6 C.
Zvinozivikanwa:
qA = 10 µC = 10 x 10-6 C = zana-5 Coulomb
q B = 10 µC = 10 x 10 -6 = 10 -5 Coulombs
q C = 20 µC = 20 x 10 -6 = 2 x 10 -5 Coulombs
Magetsi asingachinji - matambudziko nemhinduro
Simba remagetsi
1. Poindi A mumunda wemagetsi . Hukuru hwemunda wemagetsi panzvimbo A = 0.5 NC -1 . Kana 0.25-C charge yakaiswa panzvimbo A, saka simba remagetsi ripi rinoiswa pamuchina uyu?
Zvinozivikanwa:
Munda wemagetsi panzvimbo A = 0.5 NC -1
Chaja yemagetsi panzvimbo A = 0.25 C
Zvinodiwa: 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 … Verenga zvakawanda
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 pakuderera kusingachinji. 2. Girafu yekufamba kusingachinji inoratidzwa mumufananidzo … Verenga zvakawanda
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 … Verenga zvakawanda
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 … Verenga zvakawanda
