What are gravitational field and gravitational field strength? Explain.

A gravitational field is the region around a mass where it exerts a gravitational force on other objects. The gravitational field strength (g) is the force experienced by a unit mass placed in the field and is given by the formula:

g = F/m

where is the gravitational force and is the mass. On Earth, is approximately 9.8 N/kg, meaning every kilogram of mass experiences a downward force of 9.8 N due to gravity.
