Final answer:
The position vs time graph of an object that is speeding up is not a straight line.
Step-by-step explanation:
B. False. The position vs time graph of an object that is speeding up is not a straight line. When an object is speeding up, its velocity is changing, which means there is acceleration. Acceleration is the rate of change of velocity over time, and a changing velocity will result in a curved graph on a position vs time graph.
