Displacement is neither a vector nor scalar quantity, which accounts for how far away an object is after a period of time has
elapsed from its initial starting point.
Kelley is playing pool and hits the cue into the nine ball, which is directly in the center of the pool table. The nine ball travels a total of 7 meters before stopping, 1 meter to the left of the initial starting point of the nine ball.

Question
Imagine a time-position graph where the velocity of an object is constant. What will be observed on the graph concerning the slope of the line segment as well as the velocity of the object?(1 point)
Responses
The slope of the line is equal to zero and the object will be stationary.
The slope of the line is equal to zero and the object will be stationary.
The slope of the line is positive, and the object will be stationary.
The slope of the line is positive, and the object will be stationary.
The slope of the line is negative, and the object will be stationary.
The slope of the line is negative, and the object will be stationary.
The slope of the line is equal to zero and the object will be in motion.
The slope of the line is equal to zero and the object will be stationary.
Select the option that best summarizes the reason for the use of position-time graphs when studying physical science.(1 point)
