Gravitational force is the fundamental attractive force that exists between any two objects that have mass. It's a specific type of force, described by Newton's Law of Universal Gravitation, which states that the force is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Gravity is a broader term that often refers to the phenomenon or effect of this gravitational force, especially in the context of a large celestial body (like a planet or star) attracting objects towards its center. It can also refer to the acceleration experienced by objects due to this force (e.g., the acceleration due to gravity on Earth, approximately 9.8 m/s²).
In essence, gravitational force is the interaction itself, while gravity often describes the manifestation or consequence of that force, particularly the pull experienced near a massive object.
