# Free Fall is defined as falling with one gravity acting. What are some things that will help us not ?

be in freefall, or helps  slow the  pull of gravity while falling.

"Free Fall is defined as falling with one gravity acting"

No it isn't. It is defined as falling without significant influence of forces other than gravity.

The moon is in  freefall around the earth

If you jump out of an airplane you will be in freefall until the airresistance (proportional to the square of your speed) stops your acceleration

Wikipedia:

In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it. An object in the technical sense of the term "free fall" may not necessarily be falling down in the usual sense of the term. An object moving upwards would not normally be considered to be falling, but if it is subject to the force of gravity only, it is said to be in free fall. The moon is thus in free fall.

With no air resistance, it is impossible to detect that you are in free fall. But air resistance will act as a counter force and you will slow down and you will feel some weight. At terminal velocity, where falling in air you reach the point where your speed is constant, you will fell your full weight.
