On or near the Earth, the mutual gravitational forces between the center of
the Earth and the center of any other mass are 9.8 newtons (2.205 pounds),
in each direction, for each kilogram of the smaller mass.
Mass is the source of Earth's gravity. Any object that has mass has gravity.
Any object that has mass - i.e., any object - has gravity.
Yes. Why? Because any object that has a mass has gravity.
Any object with mass affects gravity
Yes, there is. In fact, anything that has mass will have gravity. In the case of Pluto, it has a mass of 0.0125x1024kg, and a force of gravity of 0.58m/s2 (which is about 6% that of Earth's gravity).
No. Mass is not gravity, any more than fat is weight. Mass is the material that you're made of. Gravity is the name for the characteristic of our universe that causes two pieces of mass to attract each other.
gravitational mass
Gravity is caused by mass which is a property of physical matter. Even hydrogen, the lightest element in the Universe, has mass and is subject to gravity. An interesting question would be why the mass has gravity?
All objects with mass have gravity, as gravity is a fundamental force that exists between all objects with mass. However, the strength of gravity can vary depending on the mass of the object and the distance between objects.
Gravity needs no specific "devices". ANY mass in the Universe attracts ANY other mass. So, the only thing you need for gravity to work, is to have two objects that have mass - so basically, any two objects.
may be the gravity of any matter is greater than it mass.
Any object with mass has gravity, no matter how small. However, the strength of the gravitational force depends on the mass of the object - the more massive the object, the stronger the gravitational force it produces.
