Kuti mudziwe kuchuluka kwa zinthu zofunika, choyamba tengani fomula ya kuchuluka komwe kwachokera.
Kuchuluka kochokera: Mphamvu
Fomula Yamphamvu
P = W / t
Kufotokozera: P = mphamvu, W = ntchito, t = nthawi
Nthawi ndi kuchuluka koyambira, pomwe W ndi kuchuluka kochokera, choncho chepetsani ntchitoyo mpaka kuchuluka koyambira kokha kutsala.
Fomula ya Bizinesi
W = F s
Kufotokozera: W = khama, F = mphamvu, s = kusamuka
Kusamutsa mphamvu ndi kuchuluka koyambira kwa kutalika, pomwe mphamvu ndi kuchuluka komwe kumachokera, choncho chepetsani mphamvuyo mpaka kuchuluka koyambira kokha kutsala.
Fomula ya mphamvu
F = ma
Kufotokozera: F = mphamvu, m = kulemera, a = kufulumira
Kulemera ndi kuchuluka koyambira kwa kutalika, pomwe kufulumira ndi kuchuluka komwe kumachokera, motero chepetsani kufulumira mpaka kuchuluka koyambira kokha kutsala.
Fomula yofulumizitsa
a = v / t
Kufotokozera: a = kuthamanga, v = liwiro, t = nthawi
Nthawi ndi kuchuluka koyambira, pomwe liwiro ndi kuchuluka komwe kumachokera, choncho chepetsani liwiro mpaka kuchuluka koyambira kokha kutsala.
Fomula ya liwiro
v = s / t
Kufotokozera: v = liwiro, s = kusamuka, t = nthawi
Kusamutsa ndi kuchuluka koyambira kwa kutalika, nthawi ndi kuchuluka koyambira.
Fomula Yamphamvu
Konzaninso njira ya mphamvu:
Kufotokozera: m = kulemera, s = kutalika, t = nthawi
Ndalama yaikulu
Mphamvu imakhala ndi kuchuluka koyambira kamodzi, kuchuluka kwapakati kawiri ndi nthawi zitatu.
Mphamvu Kukula
Kutengera ndi fomula ya mphamvu yomwe imangokhala ndi kuchuluka koyambira pamwambapa, miyeso ya mphamvu ndi iyi:
[M][L2] / [T3] = [M][L2][T3]
Chigawo Champhamvu Padziko Lonse
Kutengera ndi njira ya mphamvu ndi miyeso yomwe ili pamwambapa, gawo la mphamvu yapadziko lonse lapansi ndi:
Kilogalamu imodzi yozungulira pa sekondi iliyonse yodulidwa (kg m)2/s3)

1. Samalani ndi kuchuluka kwa zinthu zotsatirazi!
Kutengera tebulo lomwe lili pamwambapa, kuchuluka komwe kwapezeka ndi gawo lake lolondola mu International System ndi…
A. (1), (2), ndi (3)
B. (2), (3) ndi (4)
C. (2), (4) ndi (5)
D. (3), (4) ndi (5)
Kukambirana
Kuchuluka kwa thupi Zili ndi ziwiri, zomwe ndi kuchuluka koyambira ndi kuchuluka komwe kwachokera.
Ndalama yaikulu
Kuchuluka koyambira ndi kuchuluka kwa zinthu zakuthupi komwe mayunitsi ake adadziwikiratu pasadakhale. Kuchuluka koyambira 7 ndi mayunitsi ake apadziko lonse lapansi akuwonetsedwa mu tebulo ili m'munsimu.
Kuchuluka kochokera
Zochuluka zochokera kuzinthu ndi zochuluka zenizeni zomwe mayunitsi ake amachokera ku zochuluka za maziko. Kuwonjezera pa zochulukira zisanu ndi ziwiri za maziko zomwe zatchulidwa pamwambapa, zochulukira zina zakuthupi zimachokeranso. Zochuluka zochokera ku funsoli ndi voliyumu, liwiro, ndi kuchulukana.
Volume
Fomula ya voliyumu (monga voliyumu ya cuboid) = kutalika x m'lifupi x kutalika
Kutalika ndi gawo loyambira la kutalika, m'lifupi ndi gawo loyambira la kutalika, ndipo kutalika ndi gawo loyambira la kutalika. Ngakhale amagwiritsa ntchito mawu osiyanasiyana, kutalika, m'lifupi, ndi kutalika zimayesedwa pogwiritsa ntchito chida choyezera chomwecho, chomwe ndi kutalika. Kutalika, m'lifupi, ndi kutalika zilinso ndi gawo lofanana lapadziko lonse lapansi, lomwe ndi mita. Chifukwa chake, gawo lapadziko lonse lapansi la voliyumu ndi mita x mita x mita = mita ya kiyubiki, chidule chake ndi m.3
Kecepatan
Fomula ya liwiro = kusamuka / nthawi
Kusamutsa deta ndi kuchuluka koyambira kwa kutalika, ndipo nthawi ndi kuchuluka koyambira kwa nthawi. Gawo lapadziko lonse la kusamutsa deta ndi mita, ndipo gawo lapadziko lonse la nthawi ndi lachiwiri. Chifukwa chake, gawo lapadziko lonse la kusamutsa deta ndi mita/sekondi, mwachidule m/s.
Kuchulukana
Fomula yochulukira = kulemera / voliyumu
Unyinji ndi kuchuluka kofunikira, ndipo voliyumu ndi kuchuluka komwe kumachokera. Gawo lapadziko lonse la kulemera ndi kilogalamu, ndipo gawo lapadziko lonse la voliyumu ndi mita ya cubic. Chifukwa chake, gawo lapadziko lonse la kuchuluka ndi mita ya kilogalamu/cubic, chidule cha kg/m3.
Yankho lolondola ndi C.
2. Yang'anani tebulo lotsatira!
Kutengera tebulo, nambala yomwe ili mgulu la kuchuluka komwe kwachokera ndi mayunitsi mu International System (SI) ndi...
A. (1), (2), ndi (3)

Zokambirana
Kuchuluka koyambira kumaphatikizapo (1) kulemera ndi (3) kutalika. Kuchuluka komwe kumachokera kumaphatikizapo (2) kuchuluka, (4) dera, (5) magetsi.
Kuchulukana
Chigawo cha kuchuluka kwa anthu ndi kilogalamu/kiyubiki mita, chidule ndi kg/m3Onani kufotokozera mu kukambirana kwa funso nambala 1.
Luwas
Fomula ya dera (monga dera la sikweya) = kutalika x m'lifupi.
Kutalika ndi gawo loyambira la kutalika ndipo m'lifupi ndi gawo loyambira la kutalika. Gawo la kutalika la mayiko onse ndi mita ndipo gawo la m'lifupi la mayiko onse ndi mita. Chifukwa chake, gawo la dera la mayiko onse ndi mita x mita = mita yozungulira, chidule m.2.
Mphamvu yamagetsi
Gawo lapadziko lonse la mphamvu yamagetsi kapena kusiyana kwa mphamvu yamagetsi ndi Joule / Coulomb. Dzina lina la gawo lapadziko lonse la mphamvu yamagetsi ndi Volt.
Yankho lolondola ndi C.
3. Tebulo lotsatirali lili ndi kuchuluka kwa zinthu ndi mayunitsi ake.
Gulu la kuchuluka komwe kunachokera ndi mayunitsi awo mu Dongosolo Loyenera Lapadziko Lonse limawonetsedwa ndi manambala...
A. (1), (2), ndi (3)
B. (1), (3), ndi (4)
C. (2), (3), ndi (5)
D. (3), (4), ndi (5)
Zokambirana
Kuchuluka koyambira patebulo ndi (5) Kuchuluka kwa kuwala. Kuchuluka komwe kumachokera patebulo ndi (1) voliyumu, (2) kuchuluka, (3) mphamvu, ndi (4) liwiro.
Volume
Chigawo chapadziko lonse cha voliyumu ndi mita ya kiyubiki, chidule cha m3Onani kufotokozera mu kukambirana kwa funso nambala 1.
Kuchulukana
Gawo la kuchuluka kwa anthu padziko lonse lapansi ndi kilogalamu/kiyubiki mita, chidule cha kg/m3. Gramu/cm3 si gawo lapadziko lonse lapansi. Onani kufotokozera mu kukambirana kwa funso nambala 1.
Gaya
Fomula ya mphamvu = kulemera x kufulumizitsa. Kulemera ndi kuchuluka kofunikira, ndipo kufulumizitsa ndi kuchuluka komwe kumachokera. Gawo lapadziko lonse la kulemera ndi kilogalamu, chidule cha kg, ndipo gawo lapadziko lonse la kufulumizitsa ndi mita/sekondi sikweya, chidule cha m/s.2Kotero gawo la mphamvu yapadziko lonse lapansi ndi kilogalamu mita / sekondi sikweya, chidule kg m/s2Gawoli lapatsidwa dzina lapadera lakuti Newton, polemekeza katswiri wa sayansi ya zamoyo Isaac Newton.
Kecepatan
Chigawo cha liwiro lapadziko lonse lapansi ndi mita/sekondi, chidule cha m/s. Onani kufotokozera mu kukambirana kwa funso nambala 1.
Yankho lolondola ndi B.
4. Kutengera kusanthula kwa magawo, kuchuluka kwa thupi komwe kuli pansipa komwe kuli ndi miyeso yofanana ndi…
- khama ndi mphamvu
- mphamvu ndi kupanikizika
- mphamvu ndi mphamvu
- ntchito ndi kutentha
Zokambirana
Amadziwika kuti:
Kutalika kwa Muyeso Kukula = M'lifupi Kukula = Kusamuka Muyeso = L
Kukula kwa Nthawi = T
Kukula kwa Misa = M
Yankho:
Kukula kwa Malo = Kutalika Kukula x M'lifupi Kukula = [L][L] = [L]2
Kukula kwa Liwiro = Kukula kwa Kusamuka / Kukula kwa Nthawi = [L] / [T] = [L][T]-1
Kukula kwa Kuthamanga = Kukula kwa Kuthamanga / Kukula kwa Nthawi = [L][T]-1 / [T] = [L][T]-1[T]-1 = [L][T]-2
Kukula kwa Mphamvu = Kukula kwa Misa x Kukula kwa Kuthamanga = [M][L][T]-2
Mulingo wa Ntchito = Mulingo wa Mphamvu x Mulingo wa Kusamuka = [M][L][T]-2 [L] = [M][L]2[T]-2
Mphamvu Kukula = Khama Kukula / Nthawi Kukula = [M][L]2[T]-2 / [T] = [M][L]2[T]-2[T]-1 = [M][L]2[T]-3
Kukula kwa Kupanikizika = Kukula kwa Mphamvu / Kukula kwa Malo = [M][L][T]-2 / [L]2 = [M][L][T]-2 [L]-2 = [M] [L]-1[T]-2
Kukula kwa Mphamvu = Kukula kwa Misa x Kuthamanga Kukula = [M][L][T]-1
Kukula kwa Kutentha = Kukula kwa Mphamvu = Kukula kwa Ntchito = [M][L]2[T]-2
Yankho lolondola ndi D.
Katatani:
Kutentha ndi mphamvu yomwe imasamutsidwa chifukwa cha kusiyana kwa kutentha.
Ntchito ndi njira yotumizira mphamvu kudzera mu kayendedwe ka zinthu.
Kotero kukula kwa kutentha = kukula kwa mphamvu = kukula kwa ntchito.
