Question

select the correct answer. the motion of a car on a position - time graph is represented with a horizontal line. what does this indicate about the cars motion? a. its not moving. b. its moving at a constant speed. c. its moving at a constant velocity. d. its speeding up.

Explanation:

Step1: Recall position - time graph concept

In a position - time graph, the slope represents velocity. A horizontal line has a slope of zero.

Step2: Analyze the motion

If the slope of the position - time graph is zero, the object's position is not changing with time, which means it is not moving.

Answer:

A. It's not moving.
