Gravity, air resistance, force produced by the spinning of the ball.
Some forcess that affect the path of the ball is gravity which pushes the ball down to earth and wind could effect the path by blowing the ball a certain direction.
Gravitational Forces,Magnetic Forces,Spring Forces,Electric Force....... They do not depend on the path followed,they depend on initial and final point of work.

because of magnetic forces around us. and even the earth is a ball of magnet so they're always around us.
All forces produce an effect of some sort. If a force appears to have no effect, then it has been missed in observation. For example when you press your finger down onto a solid table, you might say it had no effect on the table but it would have had an observable effect on your finger, flattening the part of your finger in contact with the table.
Setting aside the physiological issues, force is applied to a baseball to accelerate it. The ball rotates in flight according to any "spin" (which is torque) applied to it as it is released. It's shape (particularly the seams) and the spin combine in its flight to apply forces that deflect it from a straight line path. Certainly gravity is pulling the ball down from the moment it is released. The analysis of fluid mechanics as it applies to the ball can become complex. Any breeze will also play a part. The batter applies a moving mass (the bat) to the ball to strike it (if he can), and accelerate it from the point of impact. We'll again see gravity clinging onto the ball as it leaves the bat, and we'll see more complex motion of the ball due to the way it moves through the air. Some spin may still be present on it after it leaves the bat, either because of the original forces that set in motion, or some spin applied by virtue of the ball impacting the bat off center, or a combination of the two.
I don't know the answer I'm asking the question does some one else know the answer
It just effects some interactions and choices in the game.
