Every object with any mass has one.
Objects of greater mass have more gravitational pull.
Large dense objects, and the closest objects.
Gravitational force exerts an attraction on objects.
Anything that has mass has a gravitational pull. I do not know the formula that determines an objects gravitational pull based on mass, but there definetly is one.
Gravitational forces between objects depend only on their masses and the distance between them. Velocity has no effect.
Gravitational force between objects is proportional to the sum of their mass and inversely proportional to the square of their distance
Yes, if the objects are side by side or at least in identical gravitational fields.
Everywhere in the universe. Gravitational fields are steeper and more intense around very massive objects such as stars and planets.
Yes if the moon fell on earth it would definetly produce a noticable magnetic field.
Anything with mass produces a gravitational field which is infinite in extent, though it gets progressively weaker with distance. Therefore there are always billions of objects producing a gravitational fields which combine into one overall field.
Gravitational fields are caused by masses.
No, there are many, many other objects, more massive or at a higher location (or both) that will have greater gravitational potential energy. Furthermore, there will be objects in stronger gravitational fields - for example, near neutron stars or black holes.
The gravitational and electric fields share similarities in that they are vector fields and both transmit forces between objects, Gravitational force is equal to the product of two MASSES divided by the distance between them squared. Electric force is equal to the product of two CHARGES divided by the distance between them squared.
yes
If there is a single property of physical objects upon which both electrical and gravitational forces depend it is the property of mass. Without mass, there is no gravity. Likewise, without mass, the are no sources for electrical fields or apparatus for separating and transmitting charges.
Gravitational attraction.
== == This is what keeps Earth in place. If there was no gravitational feilds, the Earth would crash into other planets, and space objects. It pushes the moon away from the Earth and the sun pushes the Earth away. Like repelling magnets. == == == == == == == ==
