Gravity is defined as the attraction between masses, modeled as the curvature of spacetime caused by mass. All objects, regardless of size, possess gravity, with larger masses exerting a stronger gravitational field. The fundamental equation governing gravitational force is F = G * (M*m) / r^2, where G is the gravitational constant, M is the mass of the larger object, m is the mass of the smaller object, and r is the distance between their centers. The discussion highlights the distinction between gravitational force and acceleration due to gravity, emphasizing the need for clarity in terminology. Understanding gravity involves recognizing how mass influences the curvature of spacetime and the resulting motion of objects.
