# Ubudlelwano Phakathi Kwesisindo Nesisindo: Umdanso Oyinkimbinkimbi Ku-Fiziksi Ukuqonda imiqondo yesisindo nesisindo kusenhliziyweni ye-fiziksi kanye nokuhumusha kwethu umhlaba ongokoqobo. Naphezu kokushintshana kwazo njalo olimini lwansuku zonke, isisindo nesisindo kuyizinto ezihlukile ezinezici ezihlukile. Lesi sihloko sigxila ezingosini ze … Funda kabanzi
Indlela Yokubala Amandla Angaba Khona Amandla angaba khona (PE) angenye yemiqondo eyisisekelo ku-physics. Ichaza amandla aphethwe yinto ngenxa yesikhundla sayo, ukwakheka kwayo, noma isimo sayo. Kunezinhlobo ezahlukene zamandla angaba khona okuhlanganisa amandla adonsela phansi, amandla angaba khona anwebekayo, kanye namandla angaba khona amakhemikhali. Ukuqonda ukuthi ungabala kanjani amandla angaba khona … Funda kabanzi
Umehluko Phakathi Kwe-Scalar Ne-Vector Ku-Fiziksi Emkhakheni we-physics, ukuqonda imiqondo eyisisekelo yobuningi be-scalar ne-vector kubalulekile ekuhlaziyweni okunembile kanye nencazelo yezehlakalo zomzimba. Lezi zinhlobo ezimbili zobuningi zakha isisekelo lapho kwakhelwe khona izimiso nemithetho ehlukahlukene ye-physics. Lesi sihloko sihlola … Funda kabanzi
Incazelo Yombono Ka-Einstein Wokuhlobana Imibono ka-Albert Einstein yokuhlobana, equkethe i-Special Theory of Relativity (1905) kanye ne-General Theory of Relativity (1915), yashintsha ukuqonda kwethu isikhala, isikhathi, kanye namandla adonsela phansi. Le mibono iyizinsika ze-physics yesimanje, ithonya amasimu ahlukahlukene kusukela ku-cosmology kuya ku-quantum mechanics. Kulesi sihloko, sihlola izisekelo zale mibono, … Funda kabanzi
# Izibonelo Zezinkinga Zokunyakaza Okulinganayo Okuqondile Ukunyakaza okulinganayo okuqondile, okwaziwa nangokuthi ukunyakaza okulinganayo okuqondile, kubhekisela ekuhambeni kwento ngesivinini esingaguquki endleleni eqondile. Lolu hlobo lokunyakaza lubonakala ngesivinini esingaguquki, okusho ukuthi akukho ukusheshisa. Emikhakheni eyahlukahlukene efana nefiziksi, ubunjiniyela, kanye nokwansuku zonke … Funda kabanzi
Ukuqonda Umthetho Wokuqala KaNewton Iminikelo kaSir Isaac Newton kwisayensi yayiyinto entsha, futhi uMthetho wakhe Wokuqala Wokunyakaza, ovame ukubizwa ngokuthi uMthetho Wokungabi Nandaba, umi njengenye yezimiso eziyisisekelo kakhulu kwifiziksi. Lo mthetho usungula isisekelo semishini yakudala futhi usisiza siqonde ukuziphatha kwezinto ezihambayo noma … Funda kabanzi
Imibuzo emi-3 mayelana ne-Gravity equation
1. Izinhlayiya ezintathu ngasinye esinesisindo esingu-1 kg ziseziqongweni zonxantathu olinganayo onezinhlangothi ezi-1 m ubude. Zingakanani amandla adonsela phansi atholakala yinhlayiya ngayinye ekhombayo (ku-G)?
Isixazululo
Ubukhulu bamandla adonsela phansi atholwa yinye yezinhlayiya.
F12 = G (m1)(m2) /r2 = G (1)(1) / 12 = G/1 = G
F13 = G (m1)(m3) /r2 = G (1)(1) / 12 = G/1 = G
Amandla adonsela phansi aphumela endaweni 1:
Imibuzo emi-3 mayelana nezibalo zensimu kagesi
1. Ibhola eliqhubayo elinobubanzi obuyi-10 cm linomshini kagesi ongama-500 μC. Amaphuzu A, B, no-C ahambisana nendawo ephakathi yebhola ebangeni elingama-12 cm, 10 cm kanye no-8 cm ngokulandelana ukusuka enkabeni yebhola. Bala amandla ensimu kagesi kumaphuzu A, B, kanye no-C!
Kuyaziwa:
Irediyasi yebhola eliqhubayo (R) = 10 cm = 0.1 m
Ishaja kagesi (q) = 500 μC = 500 x 10-6 C
rA = 12 cm = 0,12 m
rB = 10 cm = 0,1 m
rC = 8 cm = 0,08 m
I-Coulomb constant (k) = 9 x 109
Okufunayo: Amandla ensimu kagesi endaweni A (E)A), endaweni B (EB) kanye nasephuzwini C (EC)

Imibuzo emi-3 mayelana ne-equation eqhubekayo yaseNtwasahlobo
1. Intwasahlobo efakwe ku-free suspension inobude obuyi-10 cm. Engxenyeni ekhululekile, isisindo esingamagremu angu-200 siyalengiswa ukuze ubude bentwasahlobo bube yi-11 cm. Uma g = 10 m/s2, iyini i-spring force constant?
Kwaziwa:
Ubude bokuqala bentwasahlobo (y1) = 10 cm = 0.10 m
Ubude bokugcina bentwasahlobo (y2) = 11 cm = 0.11 m
Ukushintsha kobude bentwasahlobo (Δy) = 0.11 – 0.10 = 0.01 amamitha
Isisindo somthwalo (m) = 200 amagremu = 0.2 kg
Isisindo somthwalo (w) = mg = (0,2)(10) = 2 amaNewton
Okufunayo: I-Spring constant (k)
