Theory of gravity
The theory of gravity, proposed by Sir Isaac Newton, is based on the idea that objects with mass exert a force that causes them to move toward each other. This force is known as gravitational attraction and is responsible for phenomena such as the motion of planets around the Sun.
The theory that objects with mass move toward each other is based on Isaac Newton's law of universal gravitation. This law states that the force of gravity between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them.
Gravity is the natural force that causes objects to move toward each other. This force is a fundamental property of matter that attracts all objects with mass toward each other.
The attraction between any two objects is called gravity. It is a force that pulls objects toward each other based on their mass and distance.
Gravity is the force that pulls objects toward each other, like the Earth pulling objects towards its center. Gravitation is the theory that explains how objects attract each other due to their mass. Friction is the resistance force that occurs when objects rub against each other, which can slow down or stop motion.

gravity is a force that pulls object toward each other
The mass of the most objects is too small to cause a force large enough to notice. This is why you don't see the objects moving toward each other.
One is based on scientific data the other is based on the unproven.
a force that pulls objects towards eachother is called a gravitational force. g = (G*m1*m2)/r^2
The 'theory' of Universal Gravitation (gravity) states that there is mutual forcebetween every two masses. It says nothing about how, or whether, they move.The theory has now graduated to the status of a Law.
Gravity causes forces that attract every two objects in the universe toward each other.
