Free fall is the downward motion under the influence of
In other words, when the only force acting on an object
is gravity, the object is said to be in free fall.
In a vacuum (no air) all objects in free fall accelerate at the
same rate, regardless of mass.
There are two important motion characteristics that are true of free-
Free-falling objects do not encounter air resistance.
All free-falling objects (on Earth) accelerate downwards at a rate of
