What does the law of universal gravitation state?
Every object in the universe is attracted to every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
For every action, there is an equal and opposite reaction.
An object at rest stays at rest unless acted upon by an unbalanced force.
Force equals mass times acceleration (F=ma).
