Gravitational Fields: Factors Affecting Force

In summary, the factors that influence the force exerted by the gravitational field on a large object to another object are distance, mass, energy, and momentum. These factors are determined by the objects' properties and are combined in the energy-momentum-stress tensor, which is the source of the gravitational field.

:cry: can someone please explain and/or elaborate on:

What thoughts have you had about it?

honestly ...nothing much...
i'm wondering if there's anything else i should refer to beside the distance and the weight of the objects

Risaka-
"honestly ...nothing much...

You mean distance and mass. These are the factors that determine the mutual force of attraction between objects. The gravitational field created by an object depends on the object's mass.

Actually it depends on the objects energy (including rest mass) and momentum. These are combined in the so-called 'energy-momentum-stress' tensor which is the source of a gravitational field.
 

1. What is a gravitational field?

A gravitational field is a region in space where a massive object, such as a planet or star, can exert a force on other objects due to its mass. This force is known as gravitational force.

2. What are the factors that affect the force in a gravitational field?

The force in a gravitational field is affected by two main factors: the mass of the objects and the distance between them. The greater the mass of the objects, the stronger the gravitational force, and the closer the objects are, the stronger the force.

3. How does distance affect the force in a gravitational field?

The force in a gravitational field decreases as the distance between the objects increases. This is known as the inverse square law, meaning that the force is inversely proportional to the square of the distance between the objects.

4. Can objects in a gravitational field have more than one force acting on them?

Yes, objects in a gravitational field can have multiple forces acting on them. For example, a satellite in orbit around a planet experiences both the gravitational force from the planet and the centripetal force needed to keep it in orbit.

5. How do we measure the strength of a gravitational field?

The strength of a gravitational field can be measured using the gravitational field strength (g), which is the force per unit mass at a particular point in the field. It is measured in units of meters per second squared (m/s²).
