In a velocity-time graph, acceleration, or positive velocity, is represented by the steepness of the line. Deceleration, or negative velocity, is represented with a slope downward. Assuming that the following graph demonstrates a sprinter’s velocity over time, how would you best describe this graph? Image Source The sprinter accelerated for the majority of the duration of the chart’s plotting time. It took longer for the sprinter to decelerate than accelerate. The sprinter achieved the greatest positive velocity during the middle of the race. The sprinter maintained the same velocity after a burst of increasing acceleration.
