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.
The speed of an object changes during a fall due to the acceleration from gravity. As the object falls, it accelerates and its speed increases at a constant rate of 9.8 m/s^2 near the surface of the Earth. This means that the speed of the object will continue to increase until it reaches its terminal velocity or hits the ground.
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)

Can you describe how velocity changes during free fall?
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.
Can you describe how velocity changes during free-fall?
The velocity of an object in free-fall increases as it falls due to the acceleration of gravity acting on it. As the object falls, its velocity will continue to increase until it reaches a terminal velocity, at which point the forces of air resistance will balance out the force of gravity.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.
Who does the weight of an non-free fall opject compare with the air resistance when it is in its termenal speed?
In an object in terminal speed, the weight of the object is equal to the air resistance acting on it. This balance of forces allows the object to fall at a constant speed, as the downward force of gravity is exactly countered by the resisting force of the air.
Suppose an object in free fall is dropped from a building Its starting velocity is 0 Ignoring the effects of air resistance what is the speed of the object after falling 3 seconds?
The speed of the object after falling for 3 seconds in free fall is 29.4 m/s.

Why don't objects fall to earth at the same velocity?
Air resistance of an object can slow its fall. If every object had the same resistance, everything would fall at the same speed.
When an object reaches its termainal speed its acceleration is zero right?
Yes, when an object reaches its terminal speed, the acceleration becomes zero because the forces acting on the object (such as air resistance) have balanced out the force of gravity causing the object to fall at a constant speed. This constant speed is the terminal speed of the object.

An object launched from Earth must attain a speed of 7900 m per second to achieve a low orbit What happens if the object its maximum speed is less than 7900m per second?
If the object's maximum speed is less than 7900 m/s, it will not reach a low orbit and will fall back towards Earth due to gravity. To achieve a stable low orbit, an object needs to reach the necessary speed to counteract the gravitational pull and continuously fall towards Earth.
What is the relationship between gravity an speed?
Gravity affects the speed at which objects fall towards the Earth's surface. The greater the gravitational force, the faster an object will accelerate towards the ground. However, once an object reaches terminal velocity, the force of gravity is balanced by air resistance, and the object will fall at a constant speed.
Does the speed of free fall affected by the density of the object?
No, the speed of free fall is not affected by the density of the object. All objects fall at the same rate in a vacuum, regardless of their density, due to the effect of gravity on all objects. This phenomenon is known as the equivalence principle.
An object is in free fall until it reaches terminal velocity?
During free fall, an object accelerates due to gravity until air resistance balances the gravitational force, reaching terminal velocity. At terminal velocity, the object falls at a constant speed because the air resistance is equal to the force of gravity acting on it.
What is uniform for an object falling from a height and non uniform?
For an object falling from a height, its speed increases uniformly due to the constant acceleration of gravity. On the other hand, for non-uniform motion, the speed of the object changes unevenly over time due to varying forces or accelerations acting on it.
An object is dropped and is in free fall The speed of the falling object and the distance it falls are measured every second Which of the following is correct?
The speed stays thesame but the distance stays the same.
