Why would the ball move forward? I assumed in a vacuum, the only force acting upon the object was gravity. So, when i let go of the ball, shouldn't it be affected only by gravity and therefore drop straight down?

Hi guys, This is the scenario: a car moving at 20 mph in a vacuum (gravity exists). I drop a ball (just drop, not throw) out the window. What happens to the ball? Straight down? Forward? Backward? Thanks
