Final answer:
FALSE. The position vs time graph of an object that is speeding up is not a straight line.
Step-by-step explanation:
The statement is b. False.
The position vs time graph of an object that is speeding up is not a straight line. When an object is accelerating, its velocity is changing, and therefore the slope of the position vs time graph is not constant. The graph would be curved, with the slope getting steeper as time goes on.
