Its direction is towards the object that causes the field.
The less concentrated the field lines the smaller the force.

Gravitational field strength diagram. Draw a graph of gravitational field strength against distance. Thus a gravitational field is used to explain gravitational phenomena and is measured in newtons per kilogram nkg. If a second body is placed at distance x from the first body it will experience a gravitational attractive force towards the first body. If the distance from the point p to one of the masses is s the gravitational force towards that mass has strength g m s 2.
The gravitational field strength is the force per unit mass at a point in a gravitational field. Since gravitational field strength is proportional to gravitational force the two graphs look very similar. In physics a gravitational field is a model used to explain the influence that a massive body extends into the space around itself producing a force on another massive body. What is the gravitational field strength of the sun mass 2 x 10 30 kg on the earth mass 6 x 10 24 kg mean orbital radius 15 x 10 10 m.
It is measured in newton per kilogram. In its original concept gravity was a force between point masses. For a uniform field the equation is fm where f is the force experienced by the body and m is the. Always use the given value for g.
Gravitational field strength is a vector quantity. All objects set up a gravitational field around itself. If the gravitational field strength at any point is known then the size of the force can be calculated. By symmetry the field at p must point along the x axis so all we have to do is compute the strength of the x component of the gravitational force from one mass and double it.
