Choose the correct answer.

When an object moves with a constant acceleration, under the influence of the force of gravitation of the earth only, the object is said to have a free fall.

Free fall of a body refers to its motion only under the influence of its own weight, that is, in the existence of the gravitational pull only. No other external force will work on it. Such a motion is possible only if it will fall from a certain height above the earth's surface and is termed the free fall.
