As distance increases, value of gravitational field strength

In physics, a gravitational field is a vector field that explains the effects a body has on the space around it. It's a region of space around a body of matter where other bodies can experience gravitational force.  The gravitational field is attractive and is expressed in terms of Newton per kilogram. It's represented by arrows or field lines, which are invisible because the gravitational field force is the weakest and cannot be experienced.  The gravitational field at a point is a vector quantity usually represented by the symbol g. It's defined as the force per unit mass that would act... Show more

In physics, a gravitational field is a vector field that explains the effects a body has on the space around it. It's a region of space around a body of matter where other bodies can experience gravitational force. 

The gravitational field is attractive and is expressed in terms of Newton per kilogram. It's represented by arrows or field lines, which are invisible because the gravitational field force is the weakest and cannot be experienced. 
The gravitational field at a point is a vector quantity usually represented by the symbol g. It's defined as the force per unit mass that would act on a particle located at that point. 
The gravitational field is defined in terms of gravitational potential. The potential is the work needed by the gravitational force to move a unit mass from infinity to a final position. 
The gravitational field strength on Earth is 10 N/kg. Other planets have different gravitational field strengths. For example, the Moon has a gravitational field strength of 1.6 N/kg.
