Without air, it doesn't. All objects accelerate in free fall with the same acceleration.
If they're dropped from the same height above the surface of the same planet at the same time, they hit the ground at the same time. If any difference is noticed,
it's strictly the effect of air resistance. Try it in a tube from which the air has been
pumped out, and a feather and a Bowling ball really do fall together.
If there is an atmosphere thick enough to produce aerodynamic drag on the object in free fall, then a frictional force will develop in the opposite direction of the objects movement. Terminal velocity occurs when the reactionary drag force and the force due to gravity are in equilibrium. Since a more massive object with the same aerodynamic properties is driven by a greater force due to gravity, it will need to travel faster than a lighter object to acheive an equilibrium in the reactionary drag force. This means the more massive object achieves a higher terminal velocity and reaches the ground faster.
If there is no air resistance, it doesn't. However, the size can alter the aerodynamics, providing more or less air resistance.

When does the mass and or size of an object affect the time of its free fall?
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster
How many meters will a 2kg ball moves starting from rest fall freely in one second?
The mass is irrelevant. If the object is in free fall (that is, air resistance can be neglected), an object will fall 4.9 meters in one second.
Why light and heavier object when fall through vacuum more side by side?
This is because the weight of an object does not affect the acceleration of that object due to gravity. At Earth's surface, the acceleration due to gravity is roughly 9.8m/s2, regardless of the mass of the object.What does differ with the mass of the object is the force of gravity. Force is equal to mass multiplied by acceleration. So a one kilogram object will fall with a force of roughly 9.8 meters squared per second squared, or 9.8 Newtons (N). A two kilogram object would fall with a force of about 19.6N (2kg * 9.8m/s2). This is why when -NOT- in a vacuum, items of different mass can fall at different rates. The additional force of the more massive object will better counter the force of friction with the air, allowing it to fall faster even though it's acceleration is the same.
Does the mass effect the time taken for objects rolling down a slope?
Galileo dropped two different sized objects from the tower of Pisa and they both hit the ground at the same time. The object was to prove that the size/weight (i.e. mass) of the object would not affect the rate of fall.
How will an object size and mass affect its terminal velocity?
The terminal velocity of a falling object depends upon its aerodynamics (which is to say, its shape) rather than its size and mass.
If an object is in free fall what does it have?
Mass and inertia.
What is the relationship between free-fall acceleration and mass?
The rate of free-fall acceleration is a constant based upon the local gravity - on planet Earth the acceleration is 9.8m/s2. Mass is a function of the object being measured or observed, which can vary considerably. The two do not directly affect each other, but both taken together determine the force of the object in free-fall - by knowing the free-fall acceleration and the mass of the object, you can calculate how hard it will impact the Earth.
How does mass effect the time of a falling object?
The mass of an object does not affect the time it takes to fall to the ground in the absence of air resistance. In a vacuum, all objects fall at the same rate regardless of their mass, following Galileo's principle of free fall. However, in the presence of air resistance, the mass of the object can influence the time it takes to reach the ground.
When does the mass and or size of an object affect the time of its free fall?
if an object is lightr it will fall slower because gravity wont take it down as fast if it is heavier it will make the gravity pull it down faster
How does an object affect its accelration during free fall?
During free fall, the acceleration of an object is constant at approximately 9.8 m/s^2, regardless of its mass or size. This acceleration is due to the gravitational force pulling the object downward. Therefore, an object's mass does not affect its acceleration during free fall.
While an object near the earths surface is in free fall its mass increases?
No, the mass of an object does not increase while it is in free fall near the Earth's surface. The object's mass remains constant regardless of its motion or position.
How does gravity affect weight mass microgravity and free fall?
Gravity is the force that pulls objects towards each other; weight is the measure of the gravitational force acting on an object’s mass. In space or during free fall, objects experience microgravity, where they appear weightless because they are in a state of continuous free fall. However, the mass of the object remains the same regardless of the gravitational force affecting it.
How does the mass of an object affect it' s acceleration during free fall?
The acceleration of an object during free fall is not affected by its mass. All objects near the surface of the Earth experience the same acceleration due to gravity, which is approximately 9.8 m/s^2. This means that regardless of their mass, objects will accelerate at the same rate when falling freely.
How does the surface area of an object affect the free-fall time?
The surface area of an object does not directly affect its free-fall time. Free-fall time is primarily determined by the height from which the object falls and the acceleration due to gravity. The object's surface area may affect air resistance, which could influence the object's acceleration and speed during free fall, but it doesn't directly impact the time it takes to fall.
What Italian scientist argued that mass of an object does not affect the time the object takes to fall to the ground?
Galileo
Does the size of an object affect the time of its free fall?
No, the size of an object does not affect the time of its free fall. In a vacuum, all objects fall at the same rate regardless of their size or mass, as described by the principle of equivalence in the theory of general relativity. This means that in the absence of air resistance, objects of different sizes will reach the ground at the same time when dropped from the same height.
What Italian scientist argued that the mass of an object does not affect the time the object takes to fall to the ground?
Galileo galilei
