Terminal. It stays at that one velocity til the object hits the ground.

When it's weight balances the air resistance



That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.That is called terminal velocity.


The weight exceeds the force of air resistance, but as the speed increases the air resistance increases, so the net force (weight - air resistance) falls. When the difference becomes zero the acceleration ceases and you have terminal velocity.


When an object falls through the air it accelerates towards the ground. The faster it goes, the more air resistance there is. Eventually the resistance of the air balances the weight of the body. At this point the body ceases to accelerate; it is said to have reached terminal velocity.


newton's first law states: an object will remain at rest or at a constant velocity unless the forces on it become unbalanced. As the forces on the object are now balanced it falls at a constant velocity. For falling objects this is called the terminal velocity


At terminal velocity, the force caused by air resistance and the force caused by gravity add up to zero. If you have a weight of 500N, your terminal velocity will be that at which air resistance equals -500N. At this point, there is no net force acting on you and you will remain at this velocity until the net force becomes nonzero (from spreading your arms out or maybe hitting the ground).


In free fall, when the air resistance is equal to the weight of the falling object, we say that the object has reached ________ velocity.


-- When the forces on an objerct are 'balanced' ... meaning they add up to zero ...the object moves with a constant speed in a straight line.-- When the object's weight is greater than the force of air resistance, it keepsaccelerating downward.-- When the force of air resistance is equal to the object's weight, the forces on itare balanced, they add up to zero, and the object's speed becomes constant.-- If you started by throwing the object down at a high speed, so that the force ofair resistance was greater than its weight, its speed would decrease to the pointwhere the force of air resistance was equal to its weight. At that point, the forceson it would be balanced, they would add up to zerro, and its speed would becomeconstant.


at terminal velocity, force due to air resistance = force due to (mass * gravity)


If air resistance equals the force of gravity, the object will cease to accelerate, so its velocity will remain constant.


The ball returns to the ground with increasing velocity due to acceleration due to gravity. At a point (terminal velocity) the ball maintains a constant velocity (due to air resistance) This occurs when the weight of the ball is equal to the viscous drag of the air (air resistance) and upthrust (weight of air displaced).



The gravitational field strength of the Earth is 10 N/kg. The net force is the weight of the object (with no air resistance): W = mg = (1kg) x (10N/kg) = 10N When the air resistance balances out with the weight of the object, the ball will stop accelerating because the ball has already reached terminal velocity. In this case, the resultant force is 0.


Fnet=Fgravity-Fair resistance At terminal velocity Force Net = 0 during this time Fgravity = Fair resistance if you weight is 85kg Fgravity = Mass x G = 85x 9.8 = 833N your at terminal velocity when Air resistance is equal to 833 Newtons


Fnet=Fgravity-Fair resistance At terminal velocity Force Net = 0 during this time Fgravity = Fair resistance if you weight is 85kg Fgravity = Mass x G = 85x 9.8 = 833N your at terminal velocity when Air resistance is equal to 833 Newtons


The net force would be zero, which means the falling object would no longer be accelerating, and would be falling at terminal velocity, which is a constant velocity. Weight is a downward (negative) force and air resistance is an upward (positive) force. Fnet = weight + air resistance = -12N + 12N = 0N


The fastest velocity a falling object can reach is called its terminal velocity. This happens when the force of air resistance is equal to the downwards force of weight (gravity), so the object is in equilibrium, and thus reaches a constant velocity.



Terminal velocity that occurs during free fall describes the velocity at which drag force from the air becomes equal to the force from the weight of an object, and the object no longer accelerates, causing velocity to remain constant.


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.


There is more surface area for the air particles to hit making the weight to air resistance ratio unbalanced.


Its terminal velocity. This happens when the net force on the object is zero and therefore it stops accelerating. This makes sense intuitively because the faster something falls, the more air resistance it experiences. Once this air resistance force reaches the force of weight of the object, terminal velocity has been reached.


it varies with the weight of the round and the muzzle velocity of the weapon.However it seldom exceeds a mile.I sugguest that you watch Myth-busters.Note:If you can't ignore air resistance, then in addition to muzzle velocity, it alsodepends on both the weight and the shape of the round.If you can ignore air resistance, then it depends only on the muzzle velocity,and neither the weight nor the shape of the round has any effect on the maxheight of the arc.
