OK, if the mass is small and close to the surface of the Earth, then the force of gravity is a constant downward. Two more similar sized objects show a (1/distance) squared relationship that is proportional to each mass.
Gravity.
Gravity is a force that acts on every object in the universe. If two objects have mass, there will be a force due to Gravity between them, proportional to their masses and inversely proportional to the square of their distance between each other.
yes :D
Both Magnetism and Gravity meet that criterion.
Transfer of energy is called work.

There's no limit to the distance over which the force of gravity extends.

It acts over very large distances
yes :D

all forces are either a push or a pull. even over a distance. gravity is a pull and its opposing force, upthrust, is a push or for ipc its work
Transfer of energy is called work.
One method is to determine the effectivity of the electromagnetic force over a distance. The electromagnetic force acts over an infinite distance and therefore the photon, the particle that mediates the electromagnetic force, is massless.
since the qn is not answered yet in my opinion the cause of gravity may be the mass of the earth and the particles in it acts as a magnetic particle and all the objects in earth acts as the magnetic materials which are attracted by the earth with aforce of 9.81 m/s^2
Gravity is the weakest force. In order from strongest to weakest is the strong force, the electromagnetic force, the weak force, and gravity. However, this is relative to distance - one could consider that gravity is the strongest force because its effect can be felt over enormous distances, even astronomical distances.
