Ƙarfin gogayya mai tsauri shine ƙarfin gogayya da ke aiki akan saman abubuwan da ke hulɗa da juna lokacin da abubuwan ba sa motsi.
Siffa ta 1 yana nuna wani abu da har yanzu yana kan saman lebur ana ja shi da ƙarfi F. Idan abin ba ya motsi to fs ƙarami fiye da ƙarfin tensile (F). Idan ƙarfin tensile ya ƙaru, abin zai motsa. Lokacin da abin ya kusa motsawa, girman f ya fi girma fiye das daidai da girman ƙarfin jan (F).
Dokar Farko ta Newton ta bayyana cewa abu yana hutawa idan ƙarfin da aka samu ko jimlar ƙarfin ya yi daidai da sifili.

1. Ana jan tubalin kilogiram 1 da aka sanya a kan wani wuri mai faɗi ta amfani da na'urar auna ƙarfi (kayan aiki don auna ƙarfi). Lokacin da tubalin zai yi motsi, na'urar auna ƙarfin tana karanta Newtons 2. Saurin gudu saboda nauyi = 10 m/s2Kayyade (a) girman ƙarfin gogayya (b) ma'aunin gogayya
Tattaunawa
An sani :
Nauyin tubali (m) = 1 kg
Saurin gudu saboda nauyi (g) = 10 m/s2
Nauyin tubalin (w) = mg = (1 kg)(10 m/s2) = 10 kg m/s2 = 10 Newton
Ƙarfin taurin kai (F) = 2 Newton
Jawab :
(a) Girman ƙarfin gogayya mai motsi (f)s)
Lokacin da tubalin zai yi motsi, girman ƙarfin gogayya mai tsauri = girman ƙarfin tensile (kwatanta lissafi 1.4).
Don haka ƙarfin gogayya mai motsi (f)s) = ƙarfin tensile (F) = 2 Newton
(b) Ma'aunin gogayya mai tsayayye
