= verandering in de snelheid, er is een toename of een afname
Versnelling = a = delta v/ delta t uitgedrukt in m/s² = constant
, Toename (delta v > 0) = a is positief stijgende rechte
Afname (delta v < 0) = a is negatief dalende rechte
Hoe groter de waarde van de α , hoe steiler de rechte (1e
formule)
hoe groter de waarde van de α , hoe steiler de
parabool (2e formule)
a > 0 = dalparabool
a < 0 = bergparabool

algemene verplaatsing
De snelheidsvector ( ⃗v) raakt steeds aan de baan. De versnellingsvector a⃗ kan aan de baan raken, maar dit is niet
altijd het geval
tangentiele versnelling ⃗a t verandert de grootte v/d snelheidsvector, niet de richting
normale versnelling ⃗a N verandert de richting van de beweging
bij een EVRB verandert de bewegingsrichting niet, wel de grootte van de snelheid (normale versnelling = 0
en tangentiele versnelling aanwezig)
