(In general all test objects, if their mass is unspecified, is 1kg in mass)
[h3]Uniform Fields[/h3]
[ul]
[li]The lines represent the gravitational pull[/li]
[li]the are equally spaced out and parallel[/li]
[li]The force is constant[/li]
[li]The close the lines the stronger the force[/li]
[/ul]
[b]Stronger Uniform Field[/b]:

[h3]Radial Fields[/h3]
[ul]
[li]The straight lines represent the uniform field lines.[/li]
[li]The curved lines represent the non-uniform field lines.[/li]
[li]A magnet or compass will always point along a field line.[/li]
[/ul]

The further away from the centre of Gravity an object is, the lower the density of the field lines, therefore, the [b]GFS[/b] (Gravitational Field Strength) decreases.

[h3]Electrostatic Fields[/h3]
The test object for an Electrostatic field is an object which is positively charged.
