What is gravitation?

THE FORCE OF ATTRACTION BETWEEN TWO OBJECTS IN THE UNIVERSE IS CALLED GRAVITATION.

GRAVITATION

WHO INVENTED GRAVITATION & HOW?

When Newton saw the apple fall, Newton began to think about a specific kind of motion—gravity. Newton understood that gravity was the force of attraction between two objects. He also understood that an object with more matter –mass- exerted the greater force, or pulled smaller object toward it. That meant that the large mass of the earth pulled objects toward it. That is why the apple fell down instead of up, and why people don’t float in the air.

GRAVITATION FORCE OF ATTRACTIONThe force of attraction between all

masses in the universe; especially the attraction of the earth's mass for bodies near its surface.

Gravitation, or gravity, is a natural phenomenon by which physical bodies attract each other with a force proportional to their masses.

Gravitation radiation formation

 It is produced when massive bodies accelerate.

GRAVITATION FORCE OF ATTRACTION FORMULAG is the universal gravitational constant. This is

a universal constant so it is true everywhere.m1 is the mass of one of the objects.

m2 is the mass of the other object.r is the radius of separation between the centre

of masses of each object.FG is the force of attraction between the two

objects.

EXPLAIN THE TERM :- GRAVITATIONAL PULL?HOW IT IS RELATED WITH GRAVITATIONALN WAVES?In general terms, gravitational waves are radiated by objects whose motion involves acceleration, provided that the motion is not perfectly spherically symmetric (like an expanding or contracting sphere) or cylindrically symmetric (like a spinning disk or sphere).
