Depends what you mean by "freely falling". If you consider a body falling toward the earth through a complete vacuum, there is practically no limit to its speed. The gravitational attraction will cause the body to accelerate, so the speed will keep increasing until it collides with the earth.
If the body is falling though the atmosphere, however, we must take air resistance into account.
Let the force (downward) due to gravity be F.
Let the drag coefficient of the falling body be C.
Let m be the mass of the body, and v be the speed of the body.
Then we have the equation;
m dv/dt = F - Cv
The speed will be constant when dv/dt = 0, so then F-Cv=0.
Solving for v we get
v = F/C, which will be the terminal velocity of the falling body.
Close to earth, F=mg. The drag coefficient C is much harder to determine. It will depend on the shape of the object, and will also depend on the speed. However, you can look up values for C that can give pretty good approximations if the body is a nice shape.

The theoretical velocity of a freely falling body can be calculated using the formula v = gt, where v is the final velocity, g is the acceleration due to gravity (approximately 9.81 m/s^2 on Earth), and t is the time the body has been falling.

∙ 15y agoA free falling body has no apparent weight but weight. concept of apparent wt is valid as long as rection plane is present. be carefull don't confuse wt and apparent wt. wt remains constant till the body is outside the gavity.

∙ 14y agoThat depends on the object. Some bodies have very low freefall speeds, while others have very high ones, and most have sort of "average" speeds.
Usually sky Divers experience a maximum free fall speed (Also known as Terminal Velocity) of 60m/s (meters per second). But that also depends on weight and air conditions.

If the 'weight' of a body is the gravitational force between the body and the Earth,
then as long as the body stays at about the same distance from the center of the
Earth, its weight is constant, and has no connection with its motion.

∙ 9y agoNear Earth, the acceleration (due to Earth's gravity) is approximately 9.8 meters/second2. In other places, for example at a greater distance from Earth, or on the Moon or on other planets, the acceleration due to gravity takes on other values.

How would the terminal velocity of an object falling towards earth differ than the terminal velocity of the same object falling through water?
because water has higher viscosity than air so resisting the movement of the body in it more than air so decreasing the velocity
What is absolute velocity is it the other name for the velocity of a free falling body when the net force of air resistance and gravity is zero?
Absolute velocity refers to the speed and direction of an object relative to a fixed point, regardless of any external factors. In the context of a free falling body with zero net force due to air resistance and gravity, its absolute velocity would be constant and equal to the velocity just before air resistance became negligible.
Does the body falling to the earth travel at the same speed from the very beginning of its travel?
No, the speed of an object falling to the Earth increases due to the acceleration of gravity. At the beginning, the object has zero velocity and then accelerates until it reaches its terminal velocity, which is when the force of air resistance equals the force of gravity.
The displacement time graph of a body is ll to time axis what will you infer about the velocity of the body?
That the component of the velocity towards or away from the origin is zero. You can infer nothing at all about its overall velocity since it could be travelling in a transverse direction at any velocity.
What is acceleration of a body moving with uniform velocity?
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
What changes in a freely falling body?
In a freely falling body, its velocity increases due to the acceleration caused by gravity. The acceleration is constant (9.8 m/s^2 on Earth), and the body's motion is only affected by gravity, not air resistance. The body's position changes continuously as it falls towards the ground.
What is freely body?
A freely body is the body which is freely falling under the force of gravity i.e. an acceleration of 9.8 m/s2
A body falling freely from a height towared the earth moves with uniform?
... accelerates at approx 9.81 metres per second squared and experiences weightlessness. Friction with the air prevents continuous acceleration and the falling body reaches a maximum velocity called the terminal velocity.
If a body falls freely from infinity then it will be striking the earth with what velocity?
The body will be striking the Earth with a velocity equal to its escape velocity, which is around 11.2 km/s. At this velocity, the body will have enough kinetic energy to overcome the gravitational pull of the Earth and reach the surface.
The sumof the kinetic and potential energies of a freely falling body is?
The sum of the kinetic and potential energies of a freely falling body is constant and equal to the total mechanical energy. This is a result of the conservation of energy principle, where the body's potential energy is converted into kinetic energy as it falls, keeping the total energy constant.
What is the terminal velocity of body in a freely falling system?
Assuming the object starts at rest, it is zero. However, if the object is thrown upward or downward, its inital velocity will not be zero.
What is the direction of the acceleration of a freely falling body?
9.8 m/s2
When a body is falling freely which force act on it?
When a body is falling freely, the only force acting on it is gravity. This force causes the body to accelerate downwards at a rate of 9.81 m/s^2 near the surface of the Earth.
What is the kinetic energy for freely falling body at the ground level?
The kinetic energy of a freely falling body at ground level is equal to its potential energy at the starting height, assuming no air resistance or other external forces are acting on it. The kinetic energy is given by ( KE = \frac {1}{2} m v^2 ), where (m) is the mass of the object and (v) is its velocity just before hitting the ground.
What is the effect of mass of a freely falling body on the gravitational accelaeration?
None whatsoever.
Which type of motion is exhibited by a freely falling body?
A freely falling body exhibits uniform acceleration motion due to the force of gravity acting on it. This means that the body's speed increases by the same amount every second as it falls towards the Earth.
What is the effect of distance of freely falling body from the centre of earth on gravitational acceleration?
