Simba resimba rinokwevera pasi - matambudziko nemhinduro

1. Muviri we 1 kg wakadonha kubva pakuzorora, kubva pakukwirira kwemamita gumi.

Sarudza:

( a) Basa rinoitwa nesimba regiravhiti

(b) Kuchinja kwesimba regiravhiti

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Zvinozivikanwa:

Huremu (m) = 1 kg

Kureba (h) = 10 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Huremu (w) = mg = (1 kg)(10 m/s ² ) = 10 N

Solution:

(a) Basa rinoitwa nesimba regiravhiti

W = wh = mgh

W = (1)(10)(10) = 100 Joule

(b) Kuchinja kwesimba regiravhiti

Kuchinja kwesimba regiravhiti kwakaenzana nebasa rinoitwa negiravhiti.

Δ EP = 100 Joule

2. Chinhu che10 N chinotsvedza pasi panzvimbo yakatsetseka yakatsetseka nemamita maviri. Tsvaga basa rinoitwa nesimba rehuremu!

Zvinozivikanwa:

huremu (w) = 10 N

w _x = w chivi θ = (10)(chivi 30 ^o ) = (10)(0.5) = 5 N

d = 2 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Zvinodiwa: basa rinoitwa nesimba rinorema

Solution:

W = F d = w _x d = (5)(2) = 10 Joules

Imwe mhinduro:

Chivi 30 ^o = h / d

0.5 = awa / 2

h = (0.5)(2)

h = 1 m

Basa rinoitwa nesimba rinorema;

W = F d = wh = (10 N)(1 m) = 10 N m = 10 Joules

3. Chinhu chinorema magiramu 1,500 chiri pamamita makumi maviri pamusoro pevhu , chinodonha pasi pasina muripo. Chii chinonzi simba regiravhiti rechinhu chacho. Kukurumidza kunokonzerwa negiravhiti i10 m/s ².

Zvinozivikanwa:

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s ²

Huremu (m) = 1500 magiramu = 1500/1000 makirogiramu = 1.5 makirogiramu

Kureba (h) = mamita mashanu

Zvinodiwa: Simba regiravhiti

Solution:

PE = mgh = (1.5 kg)(10 m/s ² )(20 m) = 300 kg m ² /s ² = 300 Joules

4. Zvichibva pamufananidzo uri pazasi, kana huremu hwechinhu 1 huri 2 kg uye huremu hwechinhu 2 huri 4 kg, kuenzanisa simba rinogona kuwanikwa rechinhu 1 nechinhu 2 kuri …..

Zvinozivikanwa:

Huremu hwechinhu 1 (m₁) = 2 kg

Huremu hwechinhu 2 (m2 ₎ = makirogiramu mana

Kureba 1 (h1 ₎ = mamita mapfumbamwe

Kureba 2 (h2 ₎ = mamita mapfumbamwe

Zvinodiwa: Kuenzanisa simba rinogona kuwanikwa rechinhu 1 nechinhu 2

Solution:

PE = mgh

m = huremu (chiyero chayo chepasi rose ikirogiramu, kg yakapfupikiswa)

g = kukurumidza kunokonzerwa negiravhiti (chikamu chayo chepasi rose chiri mamita pasekondi imwe chete, chakapfupikiswa m/s ² )

h = kureba (chikamu chayo chepasi rose imita, chakapfupikiswa m)

PE = simba rekukwevera pasi (chikamu chayo chepasi rose i kg m ² /s ² kana Joule)

Simba rekukwevera rechinhu 1:

EP ₁ = m ₁ gh ₁ = (2)(g)(12) = 24 g

Simba rekukwevera rechinhu 2:

EP ₂ = m ₂ gh ₂ = (4)(g)(9) = 36 g

Kuenzanisa kwesimba rinogona kuwanikwa rechinhu 1 nechinhu 2:

PE ₁ : PE ₂

24 g : 36 g

24: 36

12/24: 12/36

2: 3
