The object that exerts gravity is an object with mass.
It is known as the "gravitational" force.
Gravity exerts an acceleration a= GM/r2 = v2/r.

Gravity is approximately a 9.8 newton force towards the center of the earth.
True. Gravity.
Gravity.
I think that gravity exerts an attractive force that gives the material potential energy.
None. Gravity IS the force in this case.
Gravity exerts an acceleration a= GM/r2 = v2/r.
The fource of Gravity.

Anything that has mass exerts a gravitational field, so yes, earth exerts one.
the mass of the earth exerts gravity on all objects around it

Not sure what you mean by "change gravity"; a nebula has mass, therefore it exerts a gravitational force.
