Under most circumstances, a falling object is slowed by any fluid through which the object falls. In normal, real world circumstances, this is the air or water.
There are attributes of the fluid that will also affect the rate of fall. The amount the object is slowed depends on how fast it is going, its shape and weight, and the viscosity and density of the fluid.
The faster the object is going, the greater the resistance of air through which it passes, resulting in a terminal velocity.
But a very heavy object is affected less than the air than a light one, so the terminal velocity of a cannonball is higher than the terminal velocity of a raindrop.
In general, the air offers more resistance to an object with more area, so a raindrop will fall faster than a feather, even if they weigh the same amount.
And since the air is denser at sea level than at a mountaintop, an object will fall faster on the mountaintop than at sea level.
Honey is more viscous than water, so a spoon that is dropped will fall slower through the honey.
From these things, it can be seen that some things are so light that the slightest motion of a sufficiently viscous fluid is enough to cause them not to fall at all, creating such a thing as murky water that will not clear. This is called Brownian motion.
The object's speed after falling for 2 seconds can be calculated using the formula: speed = acceleration due to gravity (9.81 m/s^2) x time (2 s). Therefore, the speed of the object after falling for 2 seconds would be 19.62 m/s.
If the final velocity is less than the initial velocity, the object is decreasing speed. The object has slowed down or its speed has decreased compared to when it started.
The speed of a free falling object after ten seconds from rest is approximately 98 m/s. This speed is achieved due to the acceleration of gravity, which is about 9.8 m/s².
An object is closest to being in freefall right before it hits the ground, when air resistance has slowed it down such that its acceleration is primarily due to gravity. At that point, the object's speed is nearly constant and it is falling solely due to the force of gravity.
A falling object that has reached its terminal speed no longer accelerates due to air resistance balancing the gravitational force. At terminal speed, the object continues to fall with a constant velocity and no longer gains speed.

Speed = distance / time.

Factors that increase speed of a falling object:HEIGHT - The longer an object is in the air the more speed it gains due to gravityGRAVITY - The strength of the acelleration due to gravity (eg the moon is different to earth)STARTING VELOCITY - The speed the object starts at.Factors that decrease the speed of a falling object:AIR RESISTANCE - Air resistance is a major factor however it in itself is dependant on the air pressure around the object and the surface area of the object.
The speed of a free falling object after ten seconds from rest is approximately 98 m/s. This speed is achieved due to the acceleration of gravity, which is about 9.8 m/s².
The greatest speed a falling object is known as its terminal velocity. At this speed, the drag force from the air is equal to the object's weight, and so there is no net force to accelerate the object further.

If the object is falling in vacuum, then its direction is downward, and its speed at any time is Speed = (speed when time started) + [(acceleration of gravity) x (number of seconds since time started)]. If the object is falling through air, water, or some other fluid, then the formula is much, much more complicated. It involves the object's mass and shape, and the properties of the fluid it's falling in.
it slows down their speed
Everything falls at the same speed so there is no free falling object If everything falls at the same speed then everything is a free falling object... Air resistance or deflection controls the falling speed of any object, this crucial stipulation determines falling speed. I leanred this in flight school.. please someone intelligent communicate with me?
