What acceleration due to gravity of all objects in free fall is the same?

Because
-- acceleration of an object depends on its mass and the force on it
-- the force of gravity is weaker on objects with less mass, and stronger
on objects with more mass, in such a way that
-- for every object, (gravitational force on it) divided by (mass of the object)
is always the same number, which means that
-- the acceleration of every object is always the same number.
If that answer is too complicated to follow, then an answer to the question that's
just as good is: Because that's the way that gravity works.

∙ 14y agoLets try to make this easy. Suppose you have ping pong ball and a Golf ball. If you tested to see which object falls on the ground first, you would think the golf ball because it has more mass in it. When you the ping pong ball and the golf ball in the same distance high and the ping pong ball is in vacuum air the would both fall at the same time.

∙ 14y agoNewton's Law of Universal gravitation says that F = G * m1 * m2 * r-2. G is the gravitational constant, which as you might guess from the name never changes. m1 and m2 are the masses of the objects; in this case, one of them is the Earth and the other could be anything. r is the distance between the centers of gravity of the two objects. All that boils down to: the force acting on two objects the same distance from the Earth's surface depends on a lot of values that don't change plus one that does: the mass of the object. So why should the acceleration of the two be the same, if they have different forces? Because Newton's Third Law of Motion (that Newton guy was into everything) says that F = ma, or rearranged, a = F/m. If we combine these equations, the mass term of the object drops out and we're left with a = G mE r-2 where mE is the mass of the Earth. G doesn't change, mE doesn't change, so if r is the same then a must also be the same.

Does free-fall acceleration vary on other planets?
Yep. So would terminal velocity in free-fall. It would depend entirely on the gravity of the planet.
The acceleration due to gracity of all objescts in free fall is the same Why then do some objects fall through the air at a different rate than others?
The acceleration due to gravity is the same, and in an idealized world all objects would fall at the same rate. But we do not live in an idealized world, there are other forces acting on objects as they fall. The most notable one is drag, the air resistance. This affects each object as it falls, giving them different rates of descent.
What is the acceleration of an object in a free fall at Earth's surface?
The acceleration is 9.807 meters per second squared.
Why there is zero gravity in space?
Actually there is gravity (non-zero gravity) in space. You just don't feel it when you are in free fall. For more details, read some articles (for example, in the Wikipedia) about "free fall".
How fast do objects go in free fallouter space?
You can't fall in space, there is no gravity. An object will travel as fast as it is accelerated and continue at that speed forever as there is no air resistence to slow it down.
How is the acceleration of an object in free-fall related to the acceleration due to gravity?
The acceleration in free fall IS the acceleration due to gravity, since "free fall" is the assumption that no forces other than gravity act on the object.
The acceleration due 2 gravity of all objects in free fall is the same?
if you are asking that, in general, all objects accelerate at an equal speed due to gravity in free fall, yes.they are slowed by air resistance.
In free fall do all objects fall with the same acceleration?
yes, objects fall at a rate of 9.8m/swith acceleration. For every second in free fall you must add 9.8m/s to get the acceleration of an object.
What is the definition of free fall?
when the acceleration of the freely falling object is equal to the acceleration due to gravity then there occurs free fall.
Near earth's surface an objects free fall acceleration increases as its?
Near earth's surface, an object's free fall acceleration is constant.The value is 9.8 meters (32.2 feet) per second2. That number is called the 'acceleration of gravity on earth'.
Do heavier objects fall with a greater acceleration than lighter objects in free fall?
false
How is gravity related to free fall?
Gravity and free fall are similar because they are both a force that pulls objects downward. <><><><><> Gravity is the force that pulls you down. Free fall is when you have no opposing force keeping you up.
What occurs when objects free fall near the Earths surface constant acceleration?
Yes, exactly. Free fall results in constant acceleration.
In freefall do heavier objects fall with a greater acceleration than lighter objects?
no, they fall the same acceleration ( one gravity ) neglecting air resistance; however they may reach different velocities with air resistance.
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.
When does a body has a positive acceleration during free fall?
When affected by gravity.
What occurs when objects free fall near earth's surface?
Constant acceleration
