Here is a question on a quiz I took the other day: An object is in free fall in a vacuum. Which of the following is true? A. Velocity is increasing B. Acceleration is increasing C. A and B D. None are correct I might be thinking about this wrong, but I assumed it was a vacuum in space, which means there would be no gravity, which would mean the answer is D. However, if it was a man-made vacuum on Earth, gravity would increase it's velocity, which would mean the answer is A. Can someone clear this up for me, please?
