⊕ANSWER⊕
- In Newtonian physics, free fall is defined as the motion of an object where gravity is the only force acting upon it.
- Free-falling objects do not encounter air resistance.
- All free-falling objects (on Earth) accelerate downwards at a rate of 9.8 m/s/s (often approximated as 10 m/s/s for back-of-the-envelope calculations)
- By this definition then, a skydiver is never in true free fall, even before they deploy their parachute.
- As such, all objects free fall at the same rate regardless of their mass.

ANSWER :
When an object falls under gravity with an acceleration 'g' the object is said to be a free fall. Free fall is considered to be a uniformly accelerated motion.
