Isantya

Isantya ngumlinganiselo obonakalisa okokuba ingaba into ihamba ngokukhawuleza kangakanani na.  Umyinge wokuhamba kwesantya sento ngelo xesha limisiweyo ngumgama ohamjwa yiloo nto uze  ducukucezwe okanye wohlulwahlulwe ngexesha.

Isantya sifumaneka ngo-${\displaystyle s}$ ,

${\displaystyle s=}$ ${\displaystyle d \over t}$ 

apho ke u-${\displaystyle d}$  ungumgama aze yena u-${\displaystyle t}$  abelixesha elichithiweyo. 

Zininzi ii-units zomlinganiselo wesantya. Umzekelo, isantya sokuhamba kwento singalinganiswa ngee

• imayile ngeyure (mph),
• khilomitha  ngeyure (km/h)
• mitha ngomzuzwana (m/s), noyi-SI-unit yesantya.

Xa into itshintsha isantya, ihamba ngokukhawuleza okanye chu kancinane.Ukuba siyanda isantya sento ethile, kuthiwa xa ibizwa yi-acceleration. Ukuba into iya ihamba kancinane, size isantya sinciphe, ibizwa ngokuba yideceleration, okanye i-negative acceleration.
