When a soccer ball is resting on the ground, balanced forces are present, primarily the gravitational force pulling the ball downward and the normal force exerted by the ground pushing upward. These forces cancel each other out, keeping the ball stationary. However, when the ball is kicked, an unbalanced force is applied, overcoming the gravitational force; this pushes the ball forward. As it moves through the air or rolls on the ground, additional unbalanced forces such as air resistance and friction come into play, affecting its speed and direction.
In 3-5 sentences, summarizes the balanced forces that are present when a soccer ball us 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.
