Hey!

Free fall - All objects falling towards earth under action of gravitational force of earth alone are said to be in 'free fall'.
Acceleration due to gravity (g) - Acceleration due to gravity is acceleration produced in a body in free fall due to gravitational force of earth on the body.
Escape velocity - As the name says, escape velocity is velocity needed by an body to escape from gravitational influence of a big and heavy object.
Centripetal force - Force applied on an object moving in a circular path which attracts object towards centre around which body is moving.

Answer:
Acceleration due ti gravity:-
In physics, gravitational acceleration is the free fall acceleration of an object in vacuum — without any drag. This is the steady gain in speed caused exclusively by the force of gravitational attraction.
centripetal force:-
a force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.
Escape velocity:-
the lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
