Question

What does a horizontal line on a position-time graph indicate about the object?

a. the object has a position of zero
b. the object is accelerating
c. the object has a constant, nonzero velocity
d. the object remains still

Answer 1

A horizontal line on a position-time graph indicates that the object's position is not changing over time. This means that the object is not moving, and therefore, it remains still.

The correct answer is:
d. the object remains still.
