An object which experiences either a change in the magnitude or the direction of the velocity vector can be said to be accelerating. This explains why an object moving in a circle at constant speed can be said to accelerate - the direction of the velocity changes. 3.

Can acceleration be a vector?

Since acceleration is a vector quantity, it has a direction associated with it. The direction of the acceleration vector depends on two things: whether the object is speeding up or slowing down. whether the object is moving in the + or - direction.

Is acceleration a vector quantity yes or no?

It has only magnitude, no direction. Force, displacement, and acceleration all occur with a designated direction. ... Distance is a scalar, while displacement is a vector. Force and acceleration are vectors.
