Question

what is freefall? when is the velocity of a freely falling body minimum and maximum?

Answer 1

free fall in any position of a body where gravity is on the force acting upon it. in the context of general relativity, where gravitational is reduced to a space-time curvature, a body in free fall has no force acting on it.
when a body falls freely then it is moving under gravity and acceleration due to gravity is acting downward on the body. because of this gravitational acceleration velocity of a moving body increases with a constant rate of 9.8 m/s².
