1] Free fall is the motion of an object in which it is affected only by the influence of gravity.
2] The accleration which is gained by an object because of the gravitaional force is called acceleration due to gravity.
3] The lowest velocity which a body must have in order to escape the gravitational attraction of a particular planet or other object.
4] A force which acts on a body moving in circular path and is directed towards the centre around which the body is moving.

Answer:
1) An object moves under the influence of the force of gravity alone, it is said to be falling freely.
2) The Acceleration produced in a body due gravitational force of the earth is called the acceleration due to gravity.
3) when a body is thrown vertically upward from the surface of the earth , the initial velocity of the body which is able to overcome the downward pull by the earth and can escape the earth forever is called the escape velocity.
4) The force is directed on the body is towards the centripetal force.
