Why is the law of gravity an example of a universal law? A) Gravity exists between any two masses.

B) Gravity exists only on the earth and the moon.

C) Gravity exists for masses in a closed system only.

D) Gravity exists between small masses in an open system only.

A

Explanation:

The most important part about this is not only that objects pull on each other, but that two objects attract each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them. This is known as Newton's law of universal gravitation.
