Question

An illustration of a position-time graph is utilized for learners to observe floors traveled by an individual in an elevator over a period of time.

The time-position graph shown shows that the starting point of the person traveling in the elevator is the ground floor. Moving up, or north, in the elevators, is considered positive displacement. The first floor can be assigned a value of positive one, the second a value of positive two, and so on. The starting point at the ground floor can be assigned a zero value as it is the starting point.



Consider the fact that displacement can have a positive, negative, or zero value. Can it be said that the overall displacement of the person traveling in the elevator is positive, negative, or zero?

Responses

The overall displacement is assigned a positive value.
The overall displacement is assigned a positive value.

The overall displacement is assigned a negative value.
The overall displacement is assigned a negative value.

The overall displacement is assigned a zero value.

Answer 1

To determine the overall displacement of the person traveling in the elevator, we need to consider their starting point and their final position as indicated on the position-time graph.

Since the starting point is the ground floor (assigned a value of 0), if the person moves up to the first floor (1), second floor (2), etc., their final position would be greater than their starting position.

Assuming the person ends at a floor above the ground floor, the overall displacement can be calculated as the final position minus the initial position (final position - initial position). Since the initial position is 0 (ground floor) and the final position is a positive number (such as 1, 2, or more), this confers a positive displacement.

Therefore, the correct response is:

The overall displacement is assigned a positive value.
