The best answer choice that best explains acceleration is B. A change in velocity over time.
Answer:
B. It is a change in velocity over a time period
Explanation:
Take into account that velocity is a vector quantity, so a change of it can be a change in magnitude (like in a vehicle which moves in a straight line an accelerates from 25 mph to 40 mph), or direction (like a vehicle describing a circular motion at 25 mph which receive a centripetal acceleration), or even a combination of both.
