Answer:
Newton's law of Universal Gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Explanation:
The force of gravity is an attractive force between two objects with mass. The force of gravity is directly proportional to both objects masses, and has an inverse square relationship with the distance between the objects' centers.
