the object starts at 9.81 m/s. after each second, it doubles. so.....
first second:9.81 m/s
second second: 19.62 m/s
third second: 39.24 m/s
fourth second: 78.48 m/s
fifth second: 156.96 m/s
and so on and so forth
The object remains in constant, uniform motion. That means its speed and direction of motion don't change. Note that its speed may or may not be zero.
If speed does not change then the object is moving with constant speed. when object moves in a circle its speed does not remains constant. Speed of object remains constant only if it moves along linear path.
The speed of an object at any instant in time is its instantaneous speed.
There is not one single answer for that. The terminal velocity of an object will depend on the amount of gravity (which wouldn't change much in this case), on the density of the atmosphere (which WILL change quite a bit, depending on what part of the atmosphere you are considering), and on the object's mass, size, and shape.
the conditions of free falling object are as follows: when there is no air resistance the body (object) tends to fall one by one but, when there is presence of air medium the object fall at once (simultaneously) ----salman-----
It suddenly stops and hits wherever it's landing. ---------------------------------------------- When a falling object stops accelerating then the body would continue moving with the speed attained. This speed is known as terminal speed. This is what happens when a rain drop falls from a large height through the atomosphere.
When the air resistance on a falling object equals the pull of gravity, the object reaches its terminal velocity. At terminal velocity, the object no longer accelerates and falls at a constant speed due to the balance of forces acting upon it.
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.
Speed = distance / time.
An object falling towards the Earth will stop accelerating once it reaches its terminal velocity, which is the maximum speed it can achieve due to air resistance. This happens when the force of air resistance is equal to the force of gravity acting on the object.

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.
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.
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.
