In physics, there is the concept of a gravitational field, which is a vector field utilized to explain how bodies exert attractive forces in space. This field is based on Newton's Law of Gravitation, which states that the force between two masses is dependent on their distance and size. It is described as an imaginary region around an object that causes other objects to experience an attractive force. This concept is related to mass, as the larger the mass, the stronger the gravitational pull. The Earth's gravity, for example, is due to its mass pulling on all other masses. The gravitational field is calculated using the gravitational potential, which is influenced by the mass of an object and its distance from a given point.
