Extract

Berzes spēku starp dažādām virsmām raksturo berzes koeficients, piemēram,
tērauds pa tēraudu - 0,24;
gumija pa asfaltu - 0,45;
gumija pa slapju asfaltu - 0,2.

Berze ir gan noderīga, gan kaitīga.

Berze ir noderīga, piemēram, bez berzes mēs nevarētu paspert ne soli (uz ledus ir maza berze), miera stāvokļa berzes spēks liek priekšmetiem palikt savās vietās, neļauj izslīdēt balstiem, tas notur vietās skrūves un naglas, arī diegus audumā.
