Is the change in position relative to an initial location a: speed b: velocity c: displacement d: acceleration plz

The correct answer is C. Displacement.

Explanation:

Displacement is defined as the movement of an object according to a reference frame. It is also a vector that has a direction and magnitude and its representation is through an arrow that aims from an initial position to a final position. An example of this could be when a passenger tries to move towards the back of the plane.

There is a problem related to the distance and the magnitude's displacement because people must remember that the distance traveled could be higher than the magnitude's displacement.
