Explanation:
Detailed explanation-1: -Answer. When we throw a ball into the air it falls back because of the gravitational pull that forces the ball back to the ground. . The gravitational acceleration that act on the free falling object is the effect caused by the gravitational force.
Detailed explanation-2: -When we throw or drop an object it finally returns to ground unless it is restricted to move. This is because the gravitational force of earth pulls the object towards it.
Detailed explanation-3: -The faster the air moves, the less pressure it exerts, an effect that is called Bernoulli’s Principle. This lower pressure air above the ball helps generate lift, a force that pushes the ball upward, helping it to travel farther.
