Which of the following statements is true regarding gravitational force?

Gravitational force is a fundamental interaction that exists between any two masses, and its strength is determined by the mass of the objects involved as well as the distance between them. This means that the greater the mass of either object, the stronger the gravitational attraction between them. This principle is articulated by Newton's law of universal gravitation, which states that every point mass attracts every other point mass with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Thus, the assertion that gravitational force depends on the mass of the objects involved is essential in understanding how gravity operates throughout the universe, regardless of location or the size of the objects involved.

The other options suggest misunderstandings about gravitational force. For instance, gravitational force does not only exist on Earth; it is a universal force that acts between any two masses, whether they are on Earth, in space, or elsewhere. It is also not repulsive at small distances; gravity is always an attractive force. Lastly, gravitational force affects all masses, no matter how small, not just large objects. This means even tiny particles experience gravitational attraction, albeit to a much lesser extent than larger bodies.
