Tšebeliso ea paballo ea matla a mechini bakeng sa motsamao sefofaneng se sekametseng - mathata le litharollo

1. Boloko bo thella bo boreleli sefofane se sekametseng ntle khohlano. . Block's ke eng Velocity ha e fihla fatshe. Ho potlaka ka lebaka la matla a khoheli ke 10 m/s2

Tšebeliso ea paballo ea matla a mechini bakeng sa motsamao sefofaneng se sekametseng 1Tse tsejoang:

Bolelele (h) = 8 m

Ho potlakisa ka baka la matla a khoheli (g) = 10 m/s2

o ne a batla : lebelo (v)

tharollo :

Matla a pele a mechini (ME)o) = matla a khoheli a ka bang teng (LEOTO)

MEo = PE = mgh = m (10) (8) = 80 m

Matla a ho qetela a mechini (ME)t) = matla a kinetic (HO)

MEt = KE = ½ mv2

Molao-motheo oa paballo ea matla a mechini o bolela hore matla a maiketsetso = matla a ho qetela a mechini:

MEo = 'NAt

80 m = ½ mv2

80 = ½ v2

160 = v2

v = √160 = √(16)(10) = 4√10 m/s

bona le  Rarolla lebelo la pele likarolong tse otlolohileng le tse otlolohileng tsa motsamao oa projectile

2. Ntho e boima ba 1-kg e thella tlase ka dimithara tse 8. Fumana matla a kinetic kamora hore ntho e tsamaye ka dimithara tse 5… Ho potlaka ka lebaka la matla a khoheli g = 10 m/s2

Tšebeliso ea paballo ea matla a mechini bakeng sa motsamao sefofaneng se sekametseng 2Tse tsejoang:

Boima (m) = 0.2 kg

d = limithara tse 5

Ho potlaka ka lebaka la matla a khoheli (g) = 10 m/s2

o ne a batla : matla a kinetic (KE)

Tharollo:

sebe 30o = h / d

0.5 = lihora / 5

h = (0.5)(5) = limithara tse 2.5

Phetoho ea bophahamo ba ntho ke limithara tse 2.5.

Matla a pele a mechini (ME)o) = matla a khoheli a khoheli (PE)

MEo = PE = mgh = (1)(10)(2.5) = 25 Joule

Matla a ho qetela a mechini (ME)t) = matla a kinetic (KE)

MEt = HO

Molao-motheo oa paballo ea matla a mechini e bolela hore matla a pele a mechini = matla a ho qetela a mechini:

MEo = 'NAt

25 = KE

Matla a kinetic = Lijoule tse 25.
