What is gravitation.

movement, or a tendency to move, towards a centre of gravity, as in the falling of bodies to the earth.

the force responsible for gravitation; gravity.

"Gravitation" is a property of space and mass that causes a pair of forces

between every two specks of mass anywhere. The forces are equal, their

strength depends on the amount of mass in both masses and the distance

between them, and the forces act in the direction to pull the masses together.

The word was adopted by Sir Isaac Newton to describe this phenomenon.
