Izinkinga Ezixazululiwe ku-Basic Physics

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

Umphumela we-Doppler – izinkinga nezixazululo 1. (1) umbukeli ohambela emthonjeni wezinto zokubhala (2) umthombo ohambela kumbonisi omile (3) umbukeli nomthombo basondelana (4) umbukeli nomthombo bahamba ngesivinini esifanayo Uma iphimbo elizwakalayo liphakeme kunelomsuka womthombo okhishwayo, khona-ke yisiphi isitatimende … Funda kabanzi

I-Fluid dynamics – izinkinga nezixazululo I-theorem kaTorricelli 1. Isitsha sigcwele amanzi futhi kukhona imbobo, njengoba kuboniswe esithombeni esingezansi. Uma ukusheshisa ngenxa yamandla adonsela phansi kungu-10 ms-2, liyini ijubane lamanzi kulowo mbobo? Okwaziwayo: Ukuphakama (h) = 85 cm – 40 cm = 45 cm … Funda kabanzi

Izibalo zoketshezi – izinkinga nezixazululo Ingcindezi yoketshezi 1. Uyini umehluko phakathi kwengcindezi yoketshezi yegazi phakathi kobuchopho kanye nezinyawo zomuntu okuphakama kwakhe kungu-165 cm (ake sithi ukuminyana kwegazi = 1.0 × 103 kg/m3, ukusheshisa ngenxa yamandla adonsela phansi = 10 m/s2) Kwaziwa : Ukuphakama … Funda kabanzi

Ukwanda kokushisa – izinkinga nezixazululo Ukwanda kwendawo 1. Ishidi lensimbi ku-20oC linobukhulu njengoba kuboniswe esithombeni esingezansi. Uma i-coefficient yokwanda okuqondile kwensimbi ingu-10-5 oC-1, pho luyini ushintsho endaweni ku-60oC. Okwaziwayo: Ubude bensimbi = 40 cm Ububanzi bensimbi … Funda kabanzi

Umfutho – izinkinga nezixazululo 1. Ibhola elingu-0.5-kg lihamba ngesivinini esingu-2 m/s. Bese ibhola lishaywa ngamandla F maqondana nesiqondiso sebhola, ngakho isivinini sebhola sishintshwa sibe ngu-6 m/s. Ibhola lithintana nomshayi imizuzwana engu-0.01, luyini ushintsho ekushukumeni kwebhola. Kwaziwa: … Funda kabanzi

Ukulondolozwa kwamandla okusebenza – izinkinga nezixazululo 1. Ibhulokhi le-m-kg likhishwa phezulu endizeni ebushelelezi, njengoba kuboniswe esithombeni esingezansi. Ukuqhathanisa phakathi kwamandla adonsela phansi kanye namandla e-kinetic ebhulokhi endaweni M… Isixazululo Amandla adonsela phansi endaweni M: PEM = m … Funda kabanzi

I-Impulse – izinkinga nezixazululo 1. Ibhola elingu-0.5 kg liwela ngokukhululeka lisuka ekuphakameni okungu-h1 = 7.2 amamitha futhi libonisa ukuphakama okungu-h2 = 3.2 amamitha. Ukusheshisa ngenxa yamandla adonsela phansi = 10 m/s2. Thola i-implication. Eyaziwayo: Isisindo sebhola (m) = 0.5 kg Ukuphakama kokuqala (h1) = 7.2 amamitha Ukuphakama kwesibili … Funda kabanzi

Ukushayisana Kwejubane Lomfutho – Izinkinga Nezixazululo 1. Inhlamvu yerabha engamagremu angu-40 idubule ngokuvundlile odongeni, njengoba kuboniswe esithombeni esingezansi. Inhlamvu iboniswa ngesivinini esifanayo. Luyini ushintsho ekushukumeni kwebhola? Kwaziwa: Isisindo (m) = amagremu angu-40 = 0.04 kg Ijubane lokuqala (vo) = – … Funda kabanzi

Ukuqina komsindo - izinkinga nezixazululo 1. Amaphuzu A no-B atholakala kumamitha angu-4 namamitha angu-9 ukusuka emthonjeni womsindo. Uma i-IA ne-IB zinamandla ephuzwini A nasephuzwini B, khona-ke i-IA: IB =… Yaziwa: Ibanga lephuzwi A ukusuka emthonjeni womsindo (rA) … Funda kabanzi
