Answer the following question given this paragraph: Calculating acceleration is complicated if both speed and direction are changing. It's easier to calculate acceleration when only speed is changing. To calculate acceleration without a change in direction, you just divide the change in velocity (represented by ) by the change in time (represented by ). The formula for acceleration in this case is:. Q: To calculate acceleration without a change in direction, you just divide the change in velocity by the change in what? Choices: - weight - height - size - time A:
time
