Detailed explanation-1: -STATEMENT-1 : A falling skydiver which has reached terminal velocity is considered to be in a state of free fall.
Detailed explanation-2: -As you freefall during your skydive, your body collides with these particles and encounters resistance. This air resistance then creates an oppositional force to counter the gravitational pull of the earth. The counter force of air resistance is why freefall doesn’t really feel like falling at all.
Detailed explanation-3: -As the skydiver falls faster and faster, the amount of air resistance increases more and more until it approaches the magnitude of the force of gravity. Once the force of air resistance is as large as the force of gravity, a balance of forces is attained and the skydiver no longer accelerates.
