1. Momentum
Fomula ya mphamvu ndi p = mv
Kufotokozera: p = mphamvu, m = kulemera, v = liwiro
Mulingo wa kulemera = M ndi muyeso wa liwiro = L/T = LT-1 kotero kuti miyeso patsogolo ndi MLT-1
Chigawo cha padziko lonse cha mphamvu ndi kg m/s = kg ms-1

2. Kalembedwe
Fomula ya mphamvu ndi F = ma
Kufotokozera: F = mphamvu, m = kulemera, a = kufulumira
Mulingo wa kulemera = M ndi muyeso wa kufulumira = L/T2 = LT-2 kotero kuti miyeso gaya ndi MLT-2
Chigawo cha mphamvu yapadziko lonse lapansi ndi kg m/s2 = kg ms-2

3. Mphamvu
Fomula yogwirira ntchito ndi W = F s
Kufotokozera: W = khama, F = mphamvu, s = kusamuka
Mulingo wa mphamvu ndi MLT-2 ndipo gawo losamuka ndi L kotero kuti gawolo usa ndi [M][L][T]-2 [L] = [M][L]2[T]-2

Fomula ya mphamvu ndi P = W / t
Kufotokozera: P = mphamvu, W = ntchito, t = nthawi
Miyeso ya bizinesi ndi [M][L]2[T]-2 ndipo muyeso wa nthawi ndi [T] kotero muyeso wa mphamvu ndi [M][L]2[T]-2 / [T] = [M][L]2[T]-2 [T]-1 = [M][L]2[T]-3
Chigawo cha mphamvu yapadziko lonse lapansi ndi kg m2/s3 = kg m2 s-3

Chigawo cha SI cha kulemera ndi kilogalamu (kg)
Chigawo cha SI cha kufulumizitsa ndi mita pa sekondi imodzi yozungulira sikweya (m/s)2)
Kotero gawo la mphamvu = kg m/s2 = kg ms-2

Kupanikizika = Mphamvu / Malo Ozungulira
Mphamvu ya SI ndi kg m/s2
Chigawo cha SI cha malo ozungulira ndi m2
Kotero gawo la kupanikizika = kg / ms2 = kg m-1 s-2

Mphamvu = Ntchito
Ntchito = Mphamvu x Kusamutsidwa
Chigawo cha mphamvu cha SI ndi mita ya kilogalamu pa sekondi imodzi yozungulira (kg m/s)2)

7. Hafu ya lita imodzi ya mkaka watsopano imafunika ngati chosakaniza cha msuzi wa pudding, kotero kuchuluka kwa mkaka komwe kuyenera kuwonjezeredwa ku zosakaniza za msuzi wa pudding ndi….

  1. 5000 ml ya
  2. 500 cc
  3. 50 dm3
  4. 5 mamita3

Zokambirana
Amadziwika kuti:
Kuchuluka kwa mkaka = malita 0,5
Funso: 0,5 malita = ….. ml = ….. cm3 (cc) = ….. dm3 = ….. m3
Yankho:
Lita imodzi = mamililita 1000 (1000 ml)
Lita imodzi = 0,001 m3 = 1 dm3 = 1000 masentimita3 (1000 cc)

0,5 lita = (0,5)(1000 ml) = 500 ml
0,5 dm3 = (0,5)(1000 cc) = 500 cc
Lita imodzi = 0,5 dm3 = 0,0005 m3
Yankho lolondola ndi B.

8. Ngati madzi okwana 250 cc awonjezeredwa ku ma mililita 100 a mkaka wamadzimadzi, mkaka wotsatira udzakhala….

  1. 12,5 dm3
  2. 1,25 dm3
  3. 3,5 dm3
  4. 0,35 dm3

Zokambirana
Amadziwika kuti:
Kuchuluka kwa mkaka = 100 ml
Kuchuluka kwa madzi = 250 cc = 250 cm3
Funso: 100 ml + 250 cc = ….. dm3
Yankho:
ml = mililita
cc = cm3 = masentimita a kiyubiki
dm3 = kiyubiki desimita

1 dm3 = lita imodzi = mamililita 1000 kotero mamililita 100 = malita 100/1000 = lita imodzi/10 = lita 0,1 = 0,1 dm3
1 dm3 = 1000 masentimita3 mpaka 250 cm3 = 250/1000 dm3 = 1/4 dm3 = 0,25 dm3

100 ml + 250 cm3 = 0,1 dm3 + 0,25 dm3 = 0,35 dm3

9. Kalasi yokhala ndi kutalika kwa mamita 10 ndi m'lifupi mamita 8 ili ndi pansi pa ceramic yolemera masentimita 20 x 20. Chiwerengero cha matailosi a ceramic pansi m'chipindamo ndi….

  1. 20 buah
  2. 200 buah
  3. 2000 buah
  4. 20000 buah

Zokambirana
Amadziwika kuti:
Kukula kwa kalasi:
Kutalika = mamita 10
M'lifupi = mamita 8
Malo ophunzirira = 10 m x 8 m = 80 m2

Kukula kwa ceramic:
Kutalika = 20 cm
M'lifupi = 20 cm
Malo a ceramic = 20 cm x 20 cm = 400 cm2

Funso: Chiwerengero cha matailosi pansi m'chipindamo
Yankho:
1 m = 100cm
1 mamita2 = 10.000 masentimita2
Kotero 80 m2 = 80 x 10.000 cm2 = 800.000 masentimita2

Chiwerengero cha matailosi = Malo a kalasi / Malo a matailosi
Chiwerengero cha zoumbaumba = 800.000 cm2 / 400 masentimita2
Chiwerengero cha zoumbaumba = zidutswa 2000

10. Sekondi iliyonse, madontho a madzi okwana 4 cc amatuluka m'madzi otayikira madzi. Madontho a madzi amasonkhanitsidwa mu chidebe cha malita 5. Chidebecho chimadzaza….

  1. 125 deti
  2. 200 deti
  3. 1250 deti
  4. 2000 deti

Zokambirana
Amadziwika kuti:
Lita imodzi = 1 dm3 = 1000 masentimita3

Kuchuluka kwa madzi = 4 cc = 4 cm3
Kuchuluka kwa chidebe = malita 5 = 5 dm3 = 5 x 1000 cm3 = 5000 masentimita3   
Funso: Zimatenga nthawi yayitali bwanji kuti chidebe chidzaze?
Yankho:
5000 masentimita3 / 4 masentimita3 = masekondi 1250
