which statement correctly describes the differences between positive and negative acceleration?\npositive acceleration describes a change in speed; negative acceleration describes no change in speed.\npositive acceleration describes no change in speed; negative acceleration describes a change in speed.\npositive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.\npositive acceleration describes a decrease in speed; negative acceleration describes an increase in speed.
Answer
Answer:
C. Positive acceleration describes an increase in speed; negative acceleration describes a decrease in speed.
Brief Explanations:
Acceleration is the rate of change of velocity. Positive acceleration means velocity (speed in non - vector context here) is increasing, and negative acceleration (also called deceleration) means speed is decreasing.
