Since all objects have an acceleratio due to gravity of 9.8ms-1, the only thing affecting how fast it falls is the object's surface area.Weight has nothing to do with how fast things fall, only wind resistance. Take two 16 ounce soda bottles, open one drink eight ounces. The unopened bottle is twice as heavy as the opened bottle. Close the bottle you just drank half of and drop them at the same time from a tall building, they will hit the ground at the same time. That is because gravity is a constant and the velocity of any falling object is 9.8 meters per second/per second.
Acceleration is the same for all objects at m/s^2 (32.2 ft/s^2 or 22 mph) for each second of its descent. Thus, ignoring air resistance an object starting from rest will attain a velocity of 9.81 m/s after one second, 19.62 m/s after two seconds, and so on. If you are wondering why a hammer hit the ground before a feather, look at it's aerodynamic qualities, it has nothing to do with its weight. Air resitance depends on the
coefficient of drag and has nothing to do with weight.
Two forces affect the rate at which things fall. These are gravity, which always applies, and air resistance, which only acts if there is an atmosphere. Eventually, if an object has enough distance to fall, the upward force of air resistance and the downward force of gravity will be the same. The velocity at which this occurs is called terminal velocity. For humans, when we skydive, is roughly 120 miles per hour, if we are in a prone position(meaning we are belly down, with arms and legs outstretched).
The gravity which comes from the center of the eath which is why everything is on the floor and not floating around.
Some factors that would influence the speed of a falling object:
* size of object (air resistance) * air density * object's aerodynamics Objects fall in a vacuum at 9.8 m/s2
In air, it might ... and then the shape would make a difference too. But if it's
just the falling object and gravity, then weight makes no difference.
It initially accelerates at about 9.82 m/s/s, diminishing to no acceleration at terminal velocity where force of (mass * gravity) is matched by (velocity * drag coefficient)
air resistance, mass, and gravity
gravity and air resistance
The speed of an object in free fall near the earth's surface is always 9.8 meters (32.2 feet) per second morethan it was one second earlier.
No. When an object is in free fall it has a downward force (it's mass) and an opposite, upward force of air resistance.

Terminal velocity that occurs during free fall describes the velocity at which drag force from the air becomes equal to the force from the weight of an object, and the object no longer accelerates, causing velocity to remain constant.
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.

Yes I can! I shall now do so, ignoring the effects of air resistance: During free fall, the direction of motion doesn't change. But the speed increases, steadily and continuously. The amount by which the speed increases each second is called the "acceleration of gravity". On earth, the speed is 9.8 meters per second (32.2 ft per second) greater after each second of free fall.

If the object has less speed, then it will fall back to Earth.
The speed stays thesame but the distance stays the same.
