If an object changes it's direction but not speed, then velocity vector will only change its direction but not magnitude.

* ... delta

*r... displacement vector

Formula for velocity change is *v = *r / *time

This formula doesn't tell us anything about the direction of *v, it tells us

only about its magnitude ?

Same could be said for acceleration vector a. Formula will only tell you acceleration vector's magnitude, but not it's direction ( well we do know the direction is same as *v, but since we don't know the direction of *v it's of little use ) ?
