Heyy....
A field is something that has a magnitude and a direction at every point in space. Gravity is a good example - we know there is an acceleration due to gravity of about 9.8 m/s2 down at every point in the room. Another way of saying this is that the magnitude of the Earth's gravitational field is 9.8 m/s2 down at all points in this room.
Gravitational field: g = F/m
where F is the force of gravity.
We can draw a field-line pattern to reflect that, near the Earth's surface, the field is uniform. The strength of a field is reflected by the density of field lines - a uniform field has equally-spaced field lines.

Answer:
Gravitational field :-)
Two bodies attract each other by gravitational force even if they are not in direct contact. This interaction is called action at a distance. It can be best explained in the terms of concept of field.
according to field concept:-)
#1》Every mass modifies the space around it. This modified space is called gravitational field .
#2》 When any other mass is placed in this field, it feels a gravitational force of attraction due to its interaction with the gravitational field .
The space surrounding a material body with in which its gravitational force of attraction can be experienced is called its gravitational field .
