Isantya

Isantya ngumgama ohanjwa yinto ngexesha elithile nelibekiweyo. 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.  

 Ukufumana isantya  
Isantya sifumaneka ngo-,

apho ke u- ungumgama aze yena u- abelixesha elichithiweyo.  

 Ii-units zomlinganiselo wesantya 
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.

 Ukutshintsha isantya 
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.
