The forces acting on the ball when is the ball is in the hand of the player is the force due to gravity and the normal force.
Step-by-step explanation:
1. The force due to the gravity:
Yes, baseball relates to gravity. when a player throws the ball then the ball will be launched in the air
without the gravity they ball will not come back to the ground again.Due to the gravity, the ball will fall down
2. Normal forces:
When a baseball is thrown or struck, Newton's laws of motion determines the subsequent movement. Based
on the law, the ball will be still the motion until there is an external force acting on it.
