Question

on a position-time graph, why does the x-axis only show positive values? (1 point) the x-axis shows the motion of an object, and motion cannot be assigned a negative value on a position-time graph. the x-axis shows time, and time cannot be assigned a negative value on a position-time graph. the x-axis shows position, and position cannot be assigned a negative value on a position-time graph. the x-axis is a dependent variable, and a dependent variable cannot be assigned a negative value on a position-time graph. check answer remaining attempts : 3

Explanation:

On a position - time graph, the x - axis represents time. Time is a quantity that progresses forward and cannot be negative in the context of such a graph. Motion (which could be related to position changes) can have negative values (e.g., negative displacement), and position can also have negative values (depending on the coordinate system). The x - axis (time) is an independent variable (not a dependent variable).

Answer:

The x - axis shows time, and time cannot be assigned a negative value on a position - time graph.
