Final answer:
The graph of a ball moving in a straight line typically depicts Velocity over time, where the slope represents acceleration and the horizontal line reflects steady motion.OPTION B.
Step-by-step explanation:
The graph of a ball moving in a straight line along the x-axis typically represents Velocity over time. This means that the graph will show how the velocity of the ball changes as time passes. If the ball's velocity remained constant, the graph would display as a horizontal straight line. However, if the ball's velocity changes, then the graph could either be a sloped line (representing constant acceleration or deceleration) or a curve (for changing acceleration).
In the case of constant velocity, the position vs. time graph would also be a straight line with a constant slope, reflecting steady motion in one direction. When looking at a velocity vs. time graph, you can determine the ball's acceleration and the direction of motion. Acceleration is depicted by the slope of the line; if the slope is positive, the ball is accelerating, and if negative, it is decelerating.
