7. What is the relationship between force and mass in gravitational force?

The relationship between force and mass in gravitational force is described by Newton's Law of Universal Gravitation. This law states that every particle of matter in the universe attracts every other particle 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. This can be mathematically represented as:

F = G * (m1 * m2 / r^2)

Where:

• F is the force of attraction between the two bodies,
• m1 and m2 are the masses of the two bodies,
• r is the distance between the centers of the two bodies, and
• G is the gravitational constant.

So, if the mass of either of the bodies increases, the force of gravity between them also increases. Similarly, if the distance between the bodies increases, the gravitational force decreases.
