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.(
When a soccer ball is resting on the ground, the forces acting on it are balanced. Gravity pulls the ball downwards, while the ground exerts an equal and opposite normal force upwards, resulting in no motion. However, when the ball is kicked or rolls, unbalanced forces are present. The force of the kick or the rolling action generates a greater force in one direction, causing the ball to accelerate and move.
When a soccer ball is resting on the ground, the balanced forces are the gravitational force pulling the ball downwards and the normal force exerted by the ground upwards. These forces cancel each other out, resulting in a state of equilibrium.
However, when a soccer ball is kicked and moves through the air or rolls on the ground, unbalanced forces come into play. The initial force from the kick overcomes the inertia of the ball, causing it to accelerate. In the air, the force of gravity acts on the ball, while air resistance opposes its motion. On the ground, frictional forces come into play, opposing the ball's movement. These unbalanced forces cause the ball to move or change direction.
