Question

what must be included when describing the displacement of an object?
measurement and direction
direction and speed
total distance and position
speed and total distance

Explanation:

Displacement is a vector quantity. It requires both magnitude (measurement) and direction to be fully described. Speed is a scalar related to rate of motion, total - distance is a scalar of path - length covered, and position is a location. Only measurement (magnitude) and direction are essential for displacement.

Answer:

A. measurement and direction
