Which describes an object's speed when free falling in a vacuum?
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 falls faster and faster until it strikes the ground.

Explanation:

-When objects are in free fall, the only force acting on these objects is gravity. Free fall thus occurs when an object is dropped in air that experiences no air resistance.

-Freely falling objects will fall with same acceleration due to the force of gravity and thus the object falls faster and faster as the speed increases, the net force acting on the objects is weight, their weight-to-mass ratios are always the same, their acceleration is g which is as a result of the force of gravity.
