How do the resistance and the weight of a falling object compare when terminal speed is reached?

Air resistance doesn't change with weight. It changes with speed and shape. More speed, more air resistance. If the shape has a lot of surface are to drag the air, it is more resistant, but this factor does not change with weight or speed.
This is why terminal velocity is possible. As the object falls, its speed increases, so its resistance increases also, because resistance depends directly on speed. But as this resistance is increasing, the gravity is staying the same. So, eventually, resistance catches up with gravity and cancels it out, causing an end to acceleration, or constant speed.

∙ 12y agoforce down is constant = (mass * acceleration due to gravity) newtons
force up is (velocity ^2 * drag coefficient)
terminal velocity is balance of forces (net force is 0)
if terminal velocity is known, drag coefficient can be calculated, and net force at any velocity can be calculated
say mass = 80 kg, g= 9.8 m/s^2, terminal velocity = 70 m/s
at terminal velocity:
force down 80 * 9.8 = 784 newtons
therefore force up 784 newtons = ( v^2 * drag coefficient)
so 784 = 4900 * drag coefficient
so 784/4900 = 0.16

∙ 12y agoforce down (constant) = (mass (m) kg * acceleration due to gravity (g)) newtons.
force up at any given velocity = (velocity squared * drag coefficient) newtons.
forces balance at terminal velocity
if terminal velocity known, drag coefficient can be calculated:
say terminal velocity = 70 m/s, mass = 80 kg , g = 9.8 m/s^2
forces balanced at terminal velocity
force down = 80 * 9.8 = 784 n
therefore force up 784 n = v^2 * drag coefficient
then 784/4900= drag coefficient = 0.16.
acceleration at 0 m/s is (784-0)/80 = 9.8 m/s^2
acceleration at say 20 m/s is ((784 - (20^2*0.16)) /80 = 9.0 m/s^2
acceleration at say 60 m/s is ((784 - (60^2*0.16)) /80 = 2.6 m/s^2

In free fall when the air resistance is equal to the weight of the falling object we say that the object has reached velocity.?
That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.
What is the maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to force due to gravity?
Its called terminal velocity
The maximum velocity reached by a falling object that occurs when the resistance of the medium is equal to the force due to gravity?
It's called terminal velocity! :)
When gravitational forces and air resistance equalize on an object that is falling toward earth and the object stops accelerating its velocity is called?
In that case, the object is said to have achieved terminal speed.
When air resistance equals pull of gravity?
When air resistance equals the pull of gravity, terminal velocity is reached. This is experienced by all falling objects if given enough time, and this is classically explained in Physics using skydivers.

How is terminal velocity reached by a falling object?
While an object falls faster and faster, the backwards force of air resistance will increase. Once the force of air resistance equals the force of gravitation, the object will no longer accelerate, and is said to have reached "terminal velocity".While an object falls faster and faster, the backwards force of air resistance will increase.

Does A free falling object experiences a balance of forces?
Yes, if it reaches terminal velocity, which is a constant velocity. When terminal velocity is reached, the downward gravitational force is equal to the upward force of air resistance, and the object no longer accelerates.
Why is terminal velocity an example of balanced forces?
When terminal velocity is reached, the gravitational force is balanced with the force of resistance.
When is air resistance stronger than gravity?
When terminal velocity has been reached.
