When a soccer ball is resting on the ground, the forces acting on it are balanced: the downward gravitational force that pulls it towards the Earth is countered by the upward normal force exerted by the ground. However, when the soccer ball is kicked, unbalanced forces come into play; the force of the kick provides a greater forward motion than the opposing forces of friction and air resistance. As a result, the ball accelerates and moves through the air or rolls on the ground until these forces become balanced again.
In 3-5 sentences, summarize the balanced forces that are present when a soccer ball is resting on the ground, and the unbalanced forces that are present when a soccer
ball is kicked and moves through the air or rolls on the ground.
