Depends on gravitation. On Earth, the acceleration is 9.8 meters per square second.
Technically, "free fall" means that gravity is the only force acting on a body. Since something falling to Earth is also experiencing air resistance, it is not really in free fall. Something falling to the surface of the moon would be in free fall.

∙ 9y agoFree fall, in Newtonian physics, is defined as the motion of an object or body where its weight is the only force acting upon it. Alternately, another definition of free fall is the ability to feel a sense of weightlessness. Jumping out of a plane before a parachute is deployed is an example of this.

How do objects in free fall in a vacuum accelerate?
Because in air there is gravity which can make that to accerelate
In free fall all objects fall with the same acceleration?
In free fall in a vacuum, all objects fall at the same rate of acceleration. In air, however, friction comes into play, so that various objects can fall at different rates.
What is a freely falling projectile?
It is a projectile falling with an acceleration equal to that of free fall. (an object falling in a vacuum at the earth's surface)
Which is faster to reach ground feather or ball in free fall?
In vacuum they reach ground exactly at the same time. In a medium other than vacuum the ball will reach ground first.
Do objects with larger mass fall faster outside of a vacuum?
No. Everything, no matter what the mass, free falls at about 10m/s/s.

Which would fall faster in a vacuum a science table or a bar of soap?
In a vacuum they would both fall at the same speed.
Which will fall faster a feather or ping pong ball if dropped in a vacuum?
Both will fall at the same time in vacuum because there is no resistance.
What will drop first a big ball or a small ball?
Both will reach the ground at the same time if they were dropped at the same time in a vacuum. This is a well proven fact that the mass has no effect on the acceleration of an object in a free fall in a vacuum.
Why do objects fall faster than others in free fall?
The air resistance varies due to shape. In a vacuum (space) it would be largely because one started accelerating first. It would also be (2nd order effect) because there is no perfect vacuum and one has more resistance than the other.
What is use of free fall?
You fall for free
How do different masses fall in a vacuum?
In vacuum, all masses big and small fall with the same acceleration, and reach the same speed in the same amount of time.
What is a volume empty of free molecules?
a vacuum
