Gitoya yo gushiraho, imikorere myiza yo gufunga.
Igikorwa kirahagaze neza cyane kubera geometrike yiminwa ifunga neza ifata amavuta meza, kandi kubera gukoresha ibikoresho bya reberi byagaragaye ko bikwiye kubikoresho byumusonga.
Imiterere ntoya, so static and dynamic friction ni hasi cyane.
Bikwiranye numwuka wumuyaga numwuka udafite amavuta, amavuta yambere mugihe cyo guterana bigira uruhare runini mubuzima burambye.
Imiterere yiminwa yerekana imikorere ikwiye.
Biroroshye guhuza mumashanyarazi afunze.
Irakwiriye kandi gushiramo silinderi.
