Tsanangudzo yekufamba kwemutsara kusingaenzaniswi
Kufamba kwemutsetse kusina kufanana kufamba kwekukurumidza nguva dzose. Nemamwe mashoko, kufamba kwemutsetse kusina kufanana = kufamba nekuwedzera kwekumhanya nguva dzose uye gwara rekumhanya nguva dzose. Kutungamira kwekumhanya nguva dzose = gwara rekumhanya nguva dzose = gwara rekumhanya nguva dzose = gwara rekutama nguva dzose = gwara rekutama nguva dzose = gwara rekufamba nguva dzose = gwara rekufamba nguva dzose = gwara rekufamba nguva dzose = chinhu chinofamba mumutsara wakatwasuka. Kukura kwekumhanya nguva dzose zvinoreva kuti hukuru hwekumhanya kana kumhanya hunowedzera nguva dzose.

Equation yekufamba kwemutsara kusingaenzaniswi
Kune mafomura matatu e equation anowanzoshandiswa:
v t = vo + pa
d = vot + 1⁄2 pa2
v t 2 = vo 2 + 2 ad
v o = kumhanya kwekutanga (mita/sekondi), v t = kumhanya kwekupedzisira (mita/sekondi), a = kumhanyisa (mita/sekondi), t = nguva (yechipiri), d = daro (mita).
Dambudziko remuenzaniso 1:
Chidimbu, pakutanga chakazorora, chobva chawana kumhanya kwakasimba kwe2 m/s kwemasekondi gumi . Verenga kumhanya kwekupedzisira kwechidimbu.
Solution:
Pasina equation:
Kukurumidza (a) = 2 m/s 2 zvinoreva kuwedzera kwekumhanya (v) ne2 m/s sekondi imwe neimwe. Mushure memasekonzi maviri, v = 4 m/s. Mushure memasekonzi gumi, v = 20 m/s.
Kushandisa equation:
Inozivikanwa: v o = 0 m/s (chidimbu chiri pakuzorora), a = 2 m/s 2 , t = 10 s
Zvaidiwa: v t
v t = vo o + pa = 0 + (2)(10) = 20 m/s
Dambudziko remuenzaniso 2:
Mota inofamba nenzira yakatwasuka ichimhanya makiromita makumi matanhatu paawa. Nekuti pane chipingamupinyi, mutyairi anobhureka, saka mota ine kudzikira kwe10 m/s2. Mota ichiri kufamba chinhambwe chakadii kusvika yamira mushure mekunge yabhureka?
Anozivikanwa:
v o = 60 km/h = 60(1000 m)/3600 s = 17 m/s
v t = 0 m/s (nzvimbo dzemotokari)
2a = – 10 m/s
Zvinodiwa: daro (d)
Solution:
v t 2 = vo 2 + 2 ad
(0) 2 = (17) 2 + 2(-10) d
0 = 289 – 20 d
289 = 20 d
d = 289 : 20 = 14.45 mamita
Dambudziko remuenzaniso 3:
Girafu riri pazasi igrafu yekufamba kwemutsara isingaenderane, v inomiririra kumhanya, uye t inotaura nguva. Hukuru hwekumhanya kwezvinhu zvichibva pagirafu ndehwekuti …
Dambudziko remuenzaniso 4:
Kufamba kwemotokari kunogadzira chati yekumhanya (v) vs nguva (t) sezvakaratidzwa pamufananidzo uri padivi. Kana nzvimbo iri pasi pegirafu (nzvimbo ine mumvuri) iri 48 m, saka kumhanya kwemotokari kuri …
Nzvimbo ine mumvuri = daro rese = mamita makumi mana nemasere
v o = 8 m/s, v t = 16 m/s, t = 1 m/s
v t = vo + pa
16 = 8 + a (1)
a = 16 - 8
a = 8 m/s 2
