It is gravity that will be acting on the object as always with everything on Earth, and air resistance will also be present as this opposes the direction of movement.

∙ 11y agoGravity and drag (air resistance), if any.
Where there is resistance, the mass and leading surface area of the object will define its maximum falling speed, which is called terminal velocity. At that speed, the drag force (air resistance) is equal to the accelerating force of gravity.

∙ 12y agoPhysics: Force = Mass x Accelleration
So because in free fall the only source of accelleration is gravity (assuming no air resistance) the force is the objects mass times 9.8m/s2
But based on your question i think you might be asking something more like...
What is the damage an object in free fall can do? Which is different. In that case we could use momentum:
Momentum = Mass x Velocity
In free fall velocity theoretically should just keep getting larger and larger (as the object accelerates from gravity), but in real cases air resistance stops it at a certain point.
For example: Because of this air resistance, skydivers often cant fall any faster than 720m/s. If we say a skydiver weighs 60 kg, then
Momentum = Mass x Velocity = (60) x (720) = 43200 kgXm/s, which indicates that the mass in kg is multiplied times the velocity in m/s, and is stated as "kilogram meters per second."
That's quite a bit. You could also look at energy, which has a different formula relating to velocity...
Helpful at all?

∙ 9y agoif there is force pulling on an object like lets say an apple is falling from a tree what force is acting on gravity right well it affects the speed depending on how high it falls and what caused to fall and air resistance is another force that is happening to if you get what I'm trying to say.

∙ 9y agoThe downward force that acts on it is gravity. If it's falling through some substance,
such as air or water, then the upward forces that act on it are the buoyant force
and the force of friction with the surrounding subsrance.

∙ 8y agoThe speed of an object in free-fall will depend on how far it fell and the gravitational acceleration. You gave neither.
Note: an object cannot free fall in an atmosphere as drag will eventually balance the gravitational acceleration and the object will reach terminal velocity. Free fall is only possible in a vacuum.

What is the effect of gravity on a falling object?
The effect of gravity on ANY object - falling or not - is to pull it downward. If the object is in free fall, it will accelerate downwards.
How does gravity effect a falling object?
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
How does force and gravity effect a falling object?
Gravity is a force that accelerates the falling object towards the ground.
What effect does friction and gravity have on an object?
One effect of friction on an object is the ability to make an object stop when moving such as a car's tires on the road at a stop sign. One effect of gravity is the falling of objects to Earth.
What is freefalling?
free falling is whena gravity is pulling a object or anything down and no other forces are acting on it.

free falling is whena gravity is pulling a object or anything down and no other forces are acting on it.
Definition of cause and effect?
Cause is the reason something happens. For instance, the cause of something falling is gravity. Effectis the result that happens due to the cause. For instance, the effect of gravity is the falling of the object. They are pretty much opposite.
When equals the force of gravity on a falling object the object reaches terminal velocity.?
When THE FRICTION BETWEEN THE OBJECT AND THE ATMOSPHEREequals the force of gravity on a falling object the object reaches terminal velocity.
How does gravity make things fall?
The weight of the object causes gravity to take the object falling
Explain the effect that gravity has on the velocity of falling objects?
The force of gravity causes the falling object's velocity to grow in magnitude by 9.8 meters per second every second, while its direction remains constant.
What are the impacts of relativistic gravity on falling objects on light?
what are the impacts of relativistic gravity on falling object on ligh?
What force is working on a falling object?
Gravity
How does gravity effect the velocityof a falling object?
In response to the force of gravity, the downward speed of a falling object would increase smoothly, constantly, and continuously, at the rate of 9.8 meters per second faster every second, if it were not for the resistance of the air that a falling object must plow through. This number is called the "acceleration of gravity" on Earth ... it's a different number on the moon and on every different planet.
