Which describes an object’s speed in free fall?

the object accelerates until it reaches its terminal velocity.
the object falls at a constant speed because only one force acts on it.
the object falls faster and faster until it strikes the ground.
the object speeds up and then stops when air resistance equals gravity.

the object accelerates until it reaches its terminal velocity.

Explanation:

When object falls under the gravity and friction due to air is not small or negligible then in that case object have two force on it

1). weight of the object

2). air drag

so here we will have

since the weight of the object is more than the air drag initially so the speed of the object will increase and then as the speed increases after some the air drag will balance the force due to weight

so after that the speed will become constant which is also known as terminal speed

so here correct answer would be

the object accelerates until it reaches its terminal velocity.

moisture is lackin, and organic acids are scarce.
