An object at rest on the surface of the **Earth **is experiencing a zero net force because all forces acting upon it are balanced, keeping it from motion. However, an object in free fall, while appearing 'at rest' relative to a falling observer, is under the influence of gravity and is not experiencing zero net force. ;
An object at rest on the Earth's surface experiences zero net force due to balanced forces acting on it. The downward gravitational force is countered by an upward normal force. This balance ensures the object does not accelerate or move.
