Here's a more detailed breakdown:Initial Force:When a ball is initially projected, it's a contact force applied by an external agent (like a hand or foot). This force imparts the initial velocity and direction to the ball. Gravity:After the initial force, gravity acts on the ball, pulling it downwards, causing it to accelerate downwards and curve its path. Air Resistance (Optional):In many real-world scenarios, air resistance (or drag) also plays a role, particularly at higher speeds or in windy conditions. Air resistance opposes the ball's motion, slowing it down and affecting its trajectory.
