Gravity is produced by all matter, including that of Earth.
because of the gravity of the earth
By having mass (matter) it will have gravity.
The pull of Earth's gravity gives all matter on Earth weight, which is the force exerted on an object due to gravity. This weight is the reason why objects fall towards the Earth and why all matter on Earth experiences a downward force.
Gravity seems to be an inherent property of mass; the more mass, the greater the gravity. It has nothing to do with the spinning of the Earth.
Gravity is not unique to the Earth. All matter has gravity and all matter attracts all other matter. Since the Earth has mass it also has a gracvitational field associated with it.
The force of gravity remains constant no matter where you are on Earth.
Without gravity we could not stay on the surface of the Earth -- but that wouldn't matter, because gravity is what keeps the Earth from flying apart.
Sorry, but earth is not a gravity free system. No matter where it is placed in the universe it will still have gravity that will affect all around it and that upon it.
Yes. Earth's*
the gravity does not decrease it increases because their is more matter the deeper you go down into the earth.
On earth its 9.8 m/s/s
Yes. Without the gravity, we wouldn't be able to land on the ground after we jump.
