A gravitational field as a region in which an object experiences a force due to gravitational attraction

The gravitational field strength at a point in the gravitational field is the gravitational force acting on a mass of 1 kg placed at that point.

Unit: N/kg

Symbol: g

The gravitational acceleration is the acceleration of an object due to the pull of the gravitational force.

Unit: ms-2

Important notes:

The weight of an object is defined as the gravitational force acting on the object.

Unit: Newton (N)

Free falling is a motion under force of gravity as the only force acting on the moving object.

Practically, free falling can only take place in vacuum.

Acceleration = 10ms-2 Initial velocity = 0 Displacement = high of the location

Acceleration = -10ms-2 Velocity at maximum height = 0
