Ubuningi kanye nokuntanta ngokulinganayo - izinkinga nezixazululo

1. Ibhulokhi elibekwe eziketshezini ezimbili ezinezinhlobo ezahlukene. Kuketshezi u-A, ingxenye engu-0.6 yento isemanzini. Kuketshezi u-B, ingxenye engu-0.5 yento isemanzini. Thola isilinganiso sobuningi boketshezi u-A kuya kuketshezi u-B.

Kwaziwa:

Ubuningi bebhulokhi = x

Ingxenye yento eseketshezini A = 0.6

Ubuningi boketshezi A = y

Ingxenye yento eketshezi B = 0.5

Ukulondolozwa kwamandla okusebenza ezindaweni ezigobile - izinkinga nezixazululo

1. Uma ijubane lebhola endaweni A lingu-6 m/s, ijubane lebhola endaweni B lingu-√92 m/s, kanti ukusheshisa ngenxa yamandla adonsela phansi kungu-g = 10 m/s ^2. Kuyini ukuphakama kwephuzu B (h)?

Kwaziwa:

Isivinini sebhola endaweni A (v)_A) = 6 m/s

Isivinini sebhola endaweni B (v _B ) = √92 m/s

Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s ²

Ukuphakama kwe-A (h _A ) = amamitha angu-5.6

Isikhungo samandla adonsela phansi - izinkinga nezixazululo

1. Thola izixhumanisi zesikhungo sokudonsa phansi kwento njengoba kuboniswe esithombeni esingezansi.

Isixazululo:

Hlukanisa into ibe izingxenye ezintathu.

Indawo yengxenye 1 (A ₁ ) = (2)(6) = 12 cm ²

Iphuzu eliphakathi lilele ku-x axis (x ₁ ) = 1/2 (2) = 1 cm

Iphuzu eliphakathi lilele ku-axis ka-y (y ₁ ) = 1/2 (6) = 3 cm

Ithiyori kaTorricelli - izinkinga nezixazululo

1. Ipayipi elinokuphakama okungamasentimitha ayi-100 eligcwele amanzi. Umgodi u-Q utholakala kumasentimitha ayi-10 ngaphezu komhlabathi. Liyini ibanga elivundlile (x)?

Kwaziwa:

Ibanga phakathi komgodi kanye nobuso bamanzi (h) = 100 cm – 10 cm = 90 cm = 0.9 m

Ukusheshisa ngenxa yamandla adonsela phansi (g) = 10 m/s ²

I-Vector - izinkinga nezixazululo

I-Vector kanye ne-Scalar

1. Phakathi kwezinketho ezilandelayo, okuyizibhangqa ze-scalar-vector…

A. Amandla – ukusheshisa

B. Ukucindezela – amandla

C. Ukufuduka – ​​isivinini

D. Ugesi wamanje – ingcindezi

Amandla angenzeka - izinkinga nezixazululo

Amandla adonsela phansi anamandla

1. Amandla angu-4900 Joules asetshenziswa ukuphakamisa into enesisindo esingu-50 kg ibe ukuphakama okungu-h. Kuyini ukuphakama okungu-h? Ukusheshisa ngenxa yamandla adonsela phansi (g) = 9.8 ms ^-2.

Kwaziwa:

Ushintsho lwamandla angase abe khona (ΔPE) = 4900 Joules

Isisindo sento (m) = 50 kg

Ukusheshisa ngenxa yamandla adonsela phansi (g) = 9.8 m/s ²

Isikhathi sokungahlaliseki kwezinhlayiya - izinkinga nezixazululo

1. Amabhola amabili axhunywe yinduku, njengoba kuboniswe esithombeni esingezansi. Unganaki isisindo senduku . Isisindo sebhola u-P singamagremu angu-600 kanti isisindo sebhola u-Q singamagremu angu-400. Iyini isikhathi sokungapheleli kwesistimu mayelana ne-AB?

Kwaziwa:

I-axis yokujikeleza yi-AB.

m _p = amagremu angu-600 = 0.6 kg, m _q = amagremu angu-400 = 0.4 kg

r _p = 20 cm = 0.2 m, r _q = 50 cm = 0.5 m

Okufunwayo: Isikhathi sokungakhathali kwesistimu
