Ukuhanjiswa kokushisa - izinkinga nezixazululo
1. Izinsimbi ezimbili zinobukhulu obufanayo kodwa zinezinhlobo ezahlukene. Ukushisa kwe-P = izikhathi eziphindwe kabili kunokushisa kwe-Q. Liyini izinga lokushisa phakathi kwezinsimbi ezimbili, njengoba kuboniswe esithombeni esingezansi.
Kwaziwa:
k Q = k
k P = 2k
Okufunwayo: Izinga lokushisa phakathi kwezinsimbi ezimbili

I-Torque
1. Ugongolo oluyi-140 cm ubude. Kunezenzo ezintathu zamandla kugongolo, F 1 = 20 N, F 2 = 10 N, kanye F 3 = 40 N ngesiqondiso nendawo njengoba kuboniswe esithombeni esingezansi. Iyini i- torque ebangela ukuthi ugongolo lujikeleze phakathi nendawo yobunzima bogongolo?
Kwaziwa:
Isikhungo sesisindo sitholakala enkabeni ye-beam.
Amasimu kagesi - izinkinga nezixazululo
1. Iphuzu A litholakala phakathi kwamashaji amabili. Womabili amashaji anobukhulu obufanayo kodwa uphawu oluphambene futhi ahlukaniswe yibanga elingu-a. Ubukhulu bensimu kagesi endaweni A bungu-36 N/C. Uma iphuzu A lihamba ngo-1/2a eduze nenye yamashaji womabili , buyini ubukhulu bensimu kagesi endaweni A?
Kwaziwa:
Ishaja 1 (q 1 ) = +Q
Ishaja 2 (q 2 ) = -Q
Ibanga eliphakathi kokushaja 1 nephuzu A (r 1A ) = ½ a
Amandla kagesi - izinkinga nezixazululo
1. Amacala amathathu njengoba kuboniswe esithombeni esingezansi . Yimaphi amandla kagesi atholakala ngecala B. k = 9 x 10 9 Nm 2 C −2 , 1 μC = 10 −6 C.
Kwaziwa:
qA = 10 µC = 10 x 10-6 C=10-5 I-Coulomb
q B = 10 µC = 10 x 10 -6 = 10 -5 Ama-Coulomb
q C = 20 µC = 20 x 10 -6 = 2 x 10 -5 Ama-Coulomb
Ugesi oqinile - izinkinga nezixazululo
Amandla kagesi
1. Iphuzu A ensimini kagesi . Ubukhulu bensimu kagesi endaweni A = 0.5 NC -1 . Uma kufakwa ishaja engu-0.25-C endaweni A, pho iyini amandla kagesi asetshenziswa ekushajeni.
Kwaziwa:
Insimu kagesi endaweni A = 0.5 NC -1
Ukushaja kukagesi endaweni A = 0.25 C
Kufunwa: Amandla kagesi
Imithetho kaNewton yokuhamba – izinkinga nezixazululo Umthetho wokuqala kaNewton wokuhamba 1. Uma kungekho mandla asebenzayo entweni, khona-ke: (1) into ayisheshiswanga (2) into iphumule (3) ushintsho lwejubane lento = 0 (4) into ayikwazi ukuhamba ngejubane elingaguquki Okungukuthi … Funda kabanzi
Ukunyakaza okuqondile – izinkinga nezixazululo 1. Igrafu yejubane (v) vs. isikhathi (t) eboniswe esithombeni esingezansi. Kuyini ukwehla kwejubane ngokwegrafu. Isixazululo AB = ukunyakaza ngokusheshisa okungaguquki, BC = ukunyakaza ngejubane elingaguquki, CD = ukunyakaza ngokusheshisa okungaguquki. 2. Igrafu yokunyakaza okuqondile eboniswe esithombeni … Funda kabanzi
Umthetho kaHooke kanye nokunwebeka – izinkinga nezixazululo Ushintsho lobude 1. Induku inobude obungu-L, obudonswa ngamandla ka-F. Inani lokunwebeka lingu-∆L. Ubukhulu bamandla buyini uma ushintsho lobude bungu-4∆L. Okwaziwayo: Amandla 1 (F1) = F Ushintsho … Funda kabanzi
Amandla ase-Centripetal – izinkinga nezixazululo 1. Ibhola elingamagremu angu-200, elinamathiselwe ekugcineni kwentambo, lizungezwa yindilinga evundlile enejubane eliyi-angle elingu-5 rad s-1. Uma ubude bentambo bungu-60 cm, iyini amandla ase-centripetal? Ayaziwa: Ubunzima bento (m) = 200 gr = 200/1000 kg = 2/10 … Funda kabanzi
Insimu yamandla adonsela phansi – izinkinga nezixazululo 1. Iyini isilinganiso sensimu yamandla adonsela phansi yento A kanye nento B? Eyaziwayo: Isisindo sento A (mA) = 1 Isisindo sento B (mB) = 2 Ibanga lento A ukusuka eplanethini yoMhlaba (rA) = 1 Ibanga lento … Funda kabanzi
