Izinkinga nezixazululo ezi-3 mayelana ne-Momentum equation
1. Uma ijubane lento liba ngokuphindwe kahlanu ijubane layo lokuqala, khona-ke umfutho wento uba ….. umfutho wayo wokuqala.
Kwaziwa:
Isivinini sokuqala = v
Isivinini sokugcina = 5v
Isisindo = 1
Okufunwayo: Umfutho
Isixazululo:
Ifomula ye-Momentum
p = mv = 1 (5) = 5
Uma ijubane liphindwe kahlanu kunelokuqala futhi isisindo singaguquguquki, khona-ke umfutho uphindwe kahlanu kunelokuqala.
2. Into iphonswa phezulu endizeni ebushelelezi enejubane lokuqala elingu-10 m/s. I-engeli yokuthambekela kwendiza iye endaweni evundlile ingu-30 o . Uma u-g = 10 m/s 2 , khona-ke uma isisindo sento singama-2 kg, umfutho wento ngemva komzuzwana owodwa u...
Kwaziwa:
Ijubane lokuqala (v o ) = 10 m/s
I-engeli = 30 o
Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s 2
Isisindo (m) = 2 kg
Okufunwayo: Umfutho (p)
Isixazululo:
Ifomula Yejubane
P = mv = (2 kg)(10 m/s) = 20 kg m/s
Umfutho awuxhomekile esisindweni (w = mg).
3. Inhlamvu idutshulwa ngesivinini esingu-10 m/s. Uma isisindo senhlamvu singamagremu angu-20, bala umfutho wenhlamvu.
Kwaziwa:
Isisindo sezinhlamvu (m) = amagremu angu-20 = 20/1000 kg = 0.02 kg
Isivinini (v) = 10 m/s
Okufunwayo: Umfutho (p)
Isixazululo:
Ifomula ye-Momentum
p = mv = (0,02 kg)(10 m/s) = 0,2 kg m/s
