A vacuum is a space that is completely devoid of matter, meaning there is no air or any other substance present.
In a vacuum, there is no air resistance or friction, so the ball will continue to travel in a straight line at a constant speed unless acted upon by an outside force.
Gravity still affects objects in a vacuum, so the ball will still fall towards the ground due to the Earth's gravitational pull.
In a vacuum, the ball's velocity will remain constant as long as no other forces are acting on it.
Yes, because there is no air resistance in a vacuum, the ball will not slow down as quickly and can travel farther before coming to a stop.
