When a football is at rest on the ground, the forces acting on it are balanced forces. Balanced forces are forces that have equal magnitude but act in opposite directions, resulting in a net force of zero. In this case, the two balanced forces acting on the football are:
Gravitational force: The Earth exerts a downward gravitational force on the football, pulling it towards the ground.
Normal force: The ground exerts an equal and opposite upward force on the football, preventing it from sinking into the ground.
Since these two forces are equal in magnitude and opposite in direction, they cancel each other out, resulting in a net force of zero. As a result, the football remains at rest on the ground.
