In 3 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.
When a soccer ball is resting on the ground, the balanced forces acting on it are the force due to gravity pulling it downwards and the normal force exerted by the ground pushing upwards. These forces are equal in magnitude and opposite in direction, resulting in the ball staying still. When a soccer ball is kicked or rolls, unbalanced forces come into play. The kick or the external force applied to the ball creates an unbalanced force, causing the ball to move in a particular direction, overcoming the balanced forces and inertia.
