Kuti uwane huwandu hwehuwandu hwekutanga, tanga watora fomura yehuwandu hwakawanikwa.
Huwandu hwakawanikwa: Simba
Fomura yeSimba
P=W/t
Tsananguro: P = simba, W = basa, t = nguva
Nguva inhamba yekutanga, nepo W iri nhamba inobva muhuwandu, saka deredza basa racho kusvika kwasara huwandu hwayo hwekutanga chete.
Fomura yeBhizinesi
W = F s
Tsananguro: W = kushanda nesimba, F = simba, s = kutama
Kuchinja huremu hwepakutanga, nepo simba riri huwandu hunobva, saka deredza simba zvakanyanya kusvika huwandu hwepakutanga hwasara chete.
Fomura yekumanikidza
F = ma
Tsananguro: F = simba, m = uremu, a = kukurumidza
Huremu ihuwandu hwehurefu, nepo kukwidza kuri huwandu hunobva, saka deredza kukwidza kusvika kwasara huwandu hwehuremu chete.
Fomura yekukurumidzira
a = v/t
Tsananguro: a = kukurumidza, v = kumhanya, t = nguva
Nguva inhamba yekutanga, nepo kumhanya iri huwandu hunobva, saka deredza kumhanya kusvika kwasara huwandu hwayo hwekutanga chete.
Fomura yekumhanya
v = s/t
Tsananguro: v = kumhanya, s = kutama, t = nguva
Kutamiswa kwechinhu inhamba yehurefu, nguva inhamba yehurefu.

Kukurukurirana
Zvinozivikanwa kuti:
Kureba kweDimension = Upamhi Dimension = Kutamiswa kwenzvimbo Dimension = L
Chiyero cheNguva = T
Kukura Kwehuremu = M
Mhinduro:
Saizi yeNzvimbo = Kureba Saizi x Upamhi Saizi = [L][L] = [L]2
Kureba Kwekumhanya = Kureba Kwekutamiswa / Kureba Kwenguva = [L] / [T] = [L][T]-1
Kukura Kwekukurumidza = Kukura Kwekukurumidza / Kukura Kwenguva = [L][T]-1 / [T] = [L][T]-1[T]-1 = [L][T]-2
Chiyero cheSimba = Chiyero cheMass x Chiyero cheKukurumidzira = [M][L][T]-2
Chiyero Chebasa = Chiyero Chesimba x Chiyero Chekudzingwa = [M][L][T]-2 [L] = [M][L]2[T]-2
Simba Saizi = Kushanda Saizi / Nguva Saizi = [M][L]2[T]-2 / [T] = [M][L]2[T]-2[T]-1 = [M][L]2[T]-3
Chiyero cheKumanikidzwa = Chiyero cheSimba / Chiyero cheNzvimbo = [M][L][T]-2 / [L]2 = [M][L][T]-2 [L]-2 = [M] [L]-1[T]-2    
Kukura Kwesimba = Kurema Kukura x Kumhanya Kukura = [M][L][T]-1
Chiyero cheKupisa = Chiyero cheSimba = Chiyero cheBasa = [M][L]2[T]-2
Mhinduro chaiyo ndiD.

Catatan :
Kupisa isimba rinopfuudzwa nekuda kwekusiyana kwekupisa.
Basa inzira yekufambisa simba kuburikidza nekufamba kwezvinhu.
Saka chiyero chekupisa = chiyero chesimba = chiyero chebasa.
