Answer:
An applied force, drag force and gravitational force.
Explanation:
When Amy throws a softball through the air, there is some force that acts on it. The forces that are experienced by the ball in the air as follows :
The softball experiences an applied force as a result of Amy’s throw. As the ball moves, it experiences a drag from the air it passes through. It also experiences a downward pull because of gravity.
The applied force is defined as the force applied by the person who is throwing the ball.
Drag is equivalent to the frictional force that is applied in the opposite direction.
The gravitational force always acts in downward direction.
