Yawan Jiki Girman Raka'a - Matsaloli da Magani

Yawan Jiki Girman Raka'a - Matsaloli da Magani

1.

Yawan jiki, raka'a, girma - matsaloli da mafita 1

Dangane da teburin da ke sama, wadanne adadi ne ke da ainihin raka'a da girma.

Magani:

1) lokacinta

Lissafin ƙarfin lantarki shine p = mv

p = ƙarfin motsi, m = taro, v = gudu

Girman nauyi = M da girman gudu = L/T = LT-1 don haka girman ƙarfin = MLT-1

Naúrar ƙarfin lantarki ta duniya = kg m/s = kg ms-1

2) Ƙarfi

Lissafin ƙarfi shine F = ma

F = ƙarfi, m = nauyi, a = hanzari

Girman nauyi = M da girman hanzari = L/T2 = LT-2 don haka girman ƙarfi shine MLT-2

Nau'in ƙarfi na ƙasa da ƙasa shine kg m/s2 = kg ms-2

3) Ƙarfi

Daidaiton iko shine W = F d

W = aiki, F = ƙarfi, d = matsar da

Girman ƙarfi = MLT-2 da girman sauyawa shine L don haka girman aikin shine [M][L][T]-2 [L] = [M][L]2[T]-2

Daidaiton iko shine P = W/t

P = iko, W = aiki, t = lokaci

Girman aiki = [M][L]2[T]-2 da girman lokaci = [T] don haka girman iko = [M][L]2[T]-2 / [T] = [M][L]2[T]-2 [T]-1 = [M][L]2[T]-3

Nauyin ƙarfin ƙasa da ƙasa shine kg m2/s3 = kg m2 s-3

2. Dangane da teburin da ke ƙasa, yawa tare da daidaitattun raka'a da girma sune….

Daidaiton ƙarfin lantarki shine p = mv.

Nau'in taro (m) shine kilogiram (kg) kuma naúrar saurin (v) shine mita a kowace daƙiƙa (m/s) don haka naúrar ƙarfin yana kg m/s ko kg m/sKilogram shine girman nauyi tare da girman [M], mita shine naúrar tsayi tare da girman [L], na biyu shine naúrar lokaci tare da girman [T] don haka girman motsi shine [M][L]/[T] ko [M][L][T]-1.

Ka kuma duba  Zafin jiki da zafi - matsaloli da mafita

Daidaiton ƙarfi shine F = ma.

Raka'ar nauyi (m) ita ce kilogiram (kg) kuma raka'ar hanzari (a) ita ce mita a kowace daƙiƙa murabba'i (m/s)2) don haka naúrar ƙarfi ita ce kg m/s2 ko kg ms-2Nauyin nauyi shine kilogiram tare da girman [M], naúrar tsayi shine mita tare da girman [L], naúrar lokaci shine na biyu tare da girman [T] don haka girman ƙarfi shine [M][L]/[T]2 ko [M][L][T]-2

Daidaiton iko shine P = W/t, lissafin aiki shine W = Fs s, lissafin ƙarfi shine F = m a.

Nauyin nauyi shine kilogram (kg), naúrar hanzari shine mita a kowace daƙiƙa murabba'i (m/s)2) don haka naúrar ƙarfi shine kg m/s2Naúrar matsar da ita mita ce (m), naúrar ƙarfin ita ce kg m/s2 don haka sashin aikin shine kg m/s2 xm = kg m2/s2Nau'in lokaci shine na biyu (s), naúrar aiki shine kg m2/s2 don haka naúrar wutar lantarki shine kg m2/s2 : s = kg m2/s3 ko kg m2 s-3.

Nauyin nauyi shine kilogiram tare da girman [M], naúrar tsayi shine mita tare da girman [L], naúrar lokaci shine na biyu tare da girman [T] don haka girman iko shine [M][L]2/[T]3 ko [M][L]2[T]-3.

3. Ana ƙayyade ƙarfi a matsayin ƙimar da ake yi aiki. Ko kuma ƙarfi shine rabon aiki da tazara lokaci. A ƙayyade girman iko.

Daidaiton iko:

Matsalolin jiki, raka'a, girma 3

W = aiki, F = ƙarfi, a = hanzari, v = gudu, d = nisa, t = tazara lokaci

m = nauyi (Girman na nauyi = M), d = nisa (girman nisa = L), t = lokaci (girman lokaci = T).
