Simba resimba rinokwevera pasi - matambudziko nemhinduro

1. Muviri we1 kg free-fall kubva pakuzorora, kubva pakukwirira kwemamita gumi.

Sarudza:

(A) Basa rakaitwa nechisimba of giravhiti

(b) Kuchinja kuri simba regiravhiti

Kuwedzera nekuda kwegiravhiti (g) = 10 m/s2

Simba resimba rinokwevera pasi - matambudziko nemhinduro 1Zvinozivikanwa:

Misa (m) = 1 kg

Kureba (h) = 10 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2

uremu (w) = mg = (1 kg)(10 m/s2) = 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.

ΔEP = 100 Joule

onawo  Kushandiswa kwemutemo wekutanga wethermodynamics mune mamwe maitiro ethermodynamic (Isobaric Isothermal Isochoric)

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

Simba resimba rinokwevera pasi - matambudziko nemhinduro 2Zvinozivikanwa:

huremu (w) = 10 N

wx = chivi θ = (10)(chivi 30o) = (10)(0.5) = 5 N

d = 2 m

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2

Zvaidiwa: basa rinoitwa nesimba rinorema

Solution:

W = F d = wx d = (5)(2) = 10 Joule

Imwe mhinduro:

Pasina makumi matatu nemavirio = 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

onawo  Kuwanda kweruzha - matambudziko nemhinduro

3. Chinhu che 1,500 gram pa 20 metres pamusoro pevhu, kudonha pasi pasina muripo. Chii chinonzi simba rekukwevera rechinhu chacho. Kukurumidza kunokonzerwa nekukwevera pasi i10 m/s2.

Zvinozivikanwa:

Kukurumidza kunokonzerwa negiravhiti (g) = 10 m/s2

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

Kureba (h) = mamita mashanu

Zvaidiwa: Simba regiravhiti

Solution:

PE = mgh = (1.5 kg)(10 m/s2)(20 m) = 300 kg m2/s2 = 300 Joule

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 ndiko…..

Zvinozivikanwa:

Huremu hwechinhu 1 (m1) = 2 kgSimba resimba rinokwevera pasi - matambudziko nemhinduro 5

Huremu hwechinhu 2 (m2) = 4 kg

Kureba 1 (h)1) = mamita makumi matanhatu

Kureba 2 (h)2) = mamita makumi matanhatu

Kuda: Ckuenzanisa 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 chemamita pasekondi imwe chete, chakapfupikiswa m/s2)

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

PE = simba rekukwevera pasi (chikamu chayo chepasi rose i kg m2/s2 kana Joule)

Simba rekukwevera rechinhu 1:

EP1 = m1 gh1= (2)(g)(12) = 24 g

Simba rekukwevera rechinhu 2:

EP2 = m2 gh2 = (4)(g)(9) = 36 g

Ckuenzanisa simba rinogona kuwanikwa rechinhu 1 nechinhu 2:

PE1 : PE2

24 g : 36 g

24: 36

12/24: 12/36

2: 3
