  1. In simple terms it means that the object is moving down just because of gravity and there is no other force excerted on it.  

    Free fall is motion with no acceleration other than that provided by gravity. Since this definition does not specify velocity, it also applies to objects initially moving upward. Although the definition specifically excludes all other forces such as aerodynamic drag, in nontechnical usage falling through an atmosphere is also referred to as free fall.

    Examples

    Examples of objects in free fall include:

        * A spacecraft (in space) with its rockets off (e.g. in a continuous orbit, or going up for some minutes, and then down)

        * The Moon orbiting around the Earth.

        * An object dropped in a drop tower for a physics demonstration at NASA's Zero-G Research Facility


  2. Free fall describes an object in motion due only to acceleration caused by gravity. Any planet or satellite is in free fall as their motion is caused entirely by gravity. Skydiving is technically not free fall because air resistance also affects the motion of the skydiver.
