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
