Expert Answer
Gravitational field: It is the space around a material body in which the gravitational pull can be experienced by the other bodies .
Gravitational intensity: The strength of gravitational field at a point is the measure of gravitational intensity at that point. The intensity of gravitational field of a body at a point in the field is defined as the force experienced by a body of unit mass placed at that point provided the presence of unit mass does not disturb the original gravitational field.
Gravitational potential:The gravitational potential at a point in a gravitational field is defined as the amount of work done in bringing a body of unit mass from infinity to that point without acceleration.
Gravitational potential energy of abody , at a point in the gravitational field of another body , is defined as the amount of work done in bringing the given body from infinity to that point without acceleration.
Gravitational potential energy= Gravitational potential x mass of body
