Answer

There would be two forces acting on the ball immediately after the ball leaves the hand. The force of gravity is directed straight down and the force from the air drag is also directed straight down (because the ball is moving upward). The force of gravity is a long-range force caused by the gravitational pull between the ball and the Earth. The force of air drag is a contact force caused by collisions between the ball and the particles in the air as the ball moves through the air.
