An object that's falling "freely" has no final velocity. The longer it falls, the faster it goes.

An object falling through air is not falling "freely", because the friction between it

and the air acts as if there were a force acting on it, opposite to the direction in

which it's moving. We call that firce "air resistance".

The faster the object moves, the stronger the force of air resistance grows. Eventually,

it becomes equal to the object's weight, whereupon the object has reached its final

velocity and stops accelerating.

It's not possible to know what that speed is, because it depends on the object's

shape and weight.

What is the final velocity of a freely falling object?

The final speed of an object in free fall is known as terminal velocity. Terminal velocity on Earth can range from 54 meters per second (in SI units) to 90 meters per second based on aerodynamics.


What is the hypothesis of how does air resistance affect the velocity of falling objects?

The object opposes the air and while falling of the object the initial velocity will become zero , and the final velocity will have some value's this is how air will resist the velocity of falling object ...........


Does potentail energy have an influence on the final velocity of a falling object?

yes it does. u can calculate the final velocity of the falling object with the following eqn: initial potential energy= final kinetic energy or mgh = 1/2mv2 where m=mass, h = height,v=final velocity


How does air resistance affect fallig objects?

terminal velocity is the final maximum velocity of a falling object.



What is the definition of final speed?

final velocity v of an object which starts with velocity u and then ... vector w,then the velocity of object A relative to object B is defined as the difference


How do you find final Velocity of an object?

The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).



How does mass affect the maximum velocity?

Mass by itself has no effect on velocity. In terminal velocity (velocity of an object falling through a fluid) the mass tovolume ratio (density) can change the final velocity at any given medium density, but in acceleration in a vacuum there is no impact from mass on velocity.


Do Two objects of different masses freely fall with same momentum?

No.....because we need both mass and velocity to find the momentum if velocity is same that is 9.8m/s that is of free falling bodies.........mass will effect the final result.


What is the relationship of height of a free falling object in terms of final velocity and its time of fall?

The height where from the body is dropped ie h is given as h = v2 / 2g and h = (1/2) g t2 v is the final velocity and t is time of falling g = acceleration due to gravity


How do you find acceleration falling object with only speed and distance?

a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled



Formula in getting the acceleration of a moving object?

final velocity-initial velocity --------------------------------- time


What causes a freely falling object to stop acclerating and continue to fall at its final velocity?

The answer lies in air resistance, which sets a limit, the so-called terminal velocity, on the speed of a falling object. Air resistance creates drag, a real physical phenomenon associated with objects moving through a fluid. You experience drag riding a bike. Imagine how much drag is on a jet airliner! A boat is affected by drag moving through water. Aerodynamics and hydrodynamics address these issues.


How do you find Final velocity in the absence of acceleration and initial velocity?

With no acceleration the final velocity is the same as the initial velocity. If the initial velocity is zero, the object is not moving. Unless there is some kind of force influencing the object. Then you have to calculate the acceleration: a=F/m where "F" is the force influencing the object (in Newtons) and "m" is its mass (in kilograms).


How do you find the total time that on object is in the air with an initial velocity?

You can use the equation v = u + at from kinematics v = final velocity, which in this case is 0 because the object eventually hits the floor. u = initial velocity which is given to you a = acceleration which is always 9.8m/s^2 when dealing with falling objects t = time. manouver the equation and solve for time. Keep in mind that I havn't taken into account movement in the x-y direction and assumed that it is just a falling object falling in the -y direction. CG


How do you find final velocity given height and mass?

the final velocity assuming that the mass is falling and that air resistance can be ignored but it is acceleration not mass that is important (can be gravity) final velocity is = ( (starting velocity)2 x 2 x acceleration x height )0.5


What is the final velocity of an object that decreases in kinetic energy and increases in potential energy?

Its final velocity will be zero when it reaches maximum potential energy.


What is the speed of an free falling object?

The speed of a free falling object is never constant. It changes with respect to time as a free falling object always is acted upon by g,i.e, acceleration due to gravity. thus, if v is the final speed of the particle, u is the initial velocity of the particle and t time then v= u+gt, where g =9.8/10(approx.)


If a moving body comes to a stop what will be it's final velocity?

If an object doesn't move, then its velocity is zero.


20kg mass falls 10m what is maximum velocity?

Starting from rest, the final velocity in a fall of 10 meters is 14 meters per second. Without air resistance, the mass or weight of the falling object makes absolutely no difference.



What is the difference between initial velocity and final velocity?

Initial velocity is the velocity an object begins with Final velocity is the velocity at which the object ends up in Say a car is travelling at 13 m/s and then crashes into a wall stopping it it's intitial velocity was 13 m/s and it's final velocity is at 0 m/s or Say a car starts off at 5 m/s but then accelerates from 5 m/s to 10 m/s. It's inital velocity would be 5 m/s but it's resulting or final velocity is 10 m/s
