After a soccer ball is kicked into the air, what force or forces are acting on it?
2 answers
gravity, air resistance?
The moment the ball gets kicked away from the foot, it starts accelerating, and from this point forward only two forces are put upon it: the drag with the air, which slows the ball's motion (or could be the friction from it rubbing against the ground), and gravity, which pulls it down. The ball started accelerating, and it used to be sitting still. When an object accelerates, it means that its changing speed, so it’s unbalanced.
