Answer:
In Newtonian physics, free fall is any motion of a body where gravity is the only acceleration acting upon it. In the context of general relativity, where gravitation is reduced to a space-time curvature, a body in free fall has no force acting on it.

Explanation:
In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it. By this definition then, a skydiver is never in true free fall, even before they deploy their parachute. A skydiver may be pulled towards earth by gravity, but they are also affected by air resistance, a force opposing their downward movement. For this reason it doesn’t match the strict definition of a free fall.
