Question

which statement best describes the gravitational force of an object? (1 point)
the object only has gravitational force when it is on the surface of a massive body, such as earth.
the greater the objects mass, the less its gravitational force will be.
the greater the objects mass, and the closer it is, the greater its gravitational force.
gravity only works over short distances, so the farther away an object is, the greater its gravitational force will be.

Explanation:

According to Newton's law of universal gravitation \( F = G\frac{m_1m_2}{r^2}\), where \(F\) is the gravitational force, \(G\) is the gravitational constant, \(m_1\) and \(m_2\) are the masses of two objects, and \(r\) is the distance between their centers of mass. The gravitational force is directly proportional to the product of the masses (\(m_1m_2\)) and inversely proportional to the square of the distance (\(r^2\)). So, the greater the mass of an object (assuming another object's mass is considered in the interaction) and the closer the distance between them, the greater the gravitational force.
The first option is wrong because objects have gravitational force everywhere (not just on a massive body's surface). The second option is wrong as gravitational force is directly proportional to mass. The fourth option is wrong because gravity works over long - distances (e.g., the gravitational pull between the Earth and the Moon) and gravitational force decreases with increasing distance.

Answer:

The greater the object’s mass, and the closer it is, the greater its gravitational force.
