Select the correct option for the force involved in the gravitational interaction between two objects.

The force involved in the gravitational interaction between two objects is known as gravitational force. It is a fundamental force that causes two bodies to attract each other due to their mass. The strength of this force is described by Newton's law of universal gravitation, which states:

$F = G \frac{m_1 m_2}{r^2}$

where:

• $F$ is the gravitational force between the two objects,
• $G$ is the gravitational constant ($6.674 \times 10^{-11} \, \text{N m}^2/\text{kg}^2$),
• $m_1$ and $m_2$ are the masses of the objects,
• $r$ is the distance between the centers of the two objects.

This equation illustrates how the force increases with greater masses and decreases as the distance between the objects increases. The options might include terms like attractive force, gravitational pull, or simply gravity. The correct choice would typically be one of these terms, with "gravitational force" being the most precise.
