Why is the law of gravity an example of a universal law?
The law of gravity is considered a universal law because it applies to all objects with mass in the universe. It states that every two objects in the universe attract each other with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. This law holds true regardless of the objects' size, shape, or location in the universe.

Gravity exists between small masses in an open system only.
Gravity exists for masses in a closed system only.
The law of gravity is an example of a universal law because it states that gravity exists between any two masses in the universe. This means that gravity is not limited to specific objects or locations such as the Earth and the Moon, or small masses in an open system. It applies to all objects and is present in any closed system where mass is present.
