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)
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.
When a soccer ball is resting on the ground, the forces acting on it are balanced. This means that the force of gravity pulling the ball downward is equal to the normal force exerted by the ground pushing it up, resulting in no motion. However, when the ball is kicked or rolling, unbalanced forces are at play. In the air, the force of the kick propels the ball forward while air resistance opposes its motion. When rolling on the ground, the kicking force and frictional force between the ball and the ground are unbalanced, causing the ball to move.
