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. (4 points)
1 answer
When a soccer ball is resting on the ground, the forces acting on it are balanced. The downward force of gravity is equal to the upward force exerted by the ground, resulting in a net force of zero. However, when a soccer ball is kicked, unbalanced forces come into play. The force from the player's foot is greater than the forces of friction and air resistance, causing the ball to move through the air or roll on the ground.
