This is called Terminal Velocity. Gravity pulling downwards matches the air resistance pushing upwards to cancel the acceleration out. Many people misunderstand this and believe that this means that the object falling is no longer moving, but it is speaking in terms of acceleration, not speed. So the acceleration from before terminal velocity was reached will still be in affect, but the object will be neither gaining or losing speed.
No, terminal velocity is the speed at which an object comes to a resting point in acceleration. This happens when the effect of gravity on said object becomes balanced with the air resistance.
Dictionary definition: the velocity at which a falling body moves through a medium, as air, when the force of resistance of the medium is equal in magnitude and opposite in direction to the force of gravity.
This is commonly called the terminal speed (or velocity if you want the vector form).
Then acceleration becomes zero, and the object
continues falling at a constant speed.

That is the object's terminal velocity.
If its speed of fall is no longer changing, then its acceleration is zero. That tells you that the forces on it must be balanced, so the upward force of air resistance must be exactly equal to the downward force of gravity.
It's called terminal velocity and it's when the downward force of gravity equals the upward force of drag due to air resistance.
By definition, if he is accelerating, then it is an unbalanced force ... which means he JUST jumped out the plane and his downward speed in increasing. Once he reaches a particular speed (called terminal velocity; lets call it for a general case of about 110 mph), the force of DRAG will be equal to the force due to gravity and he will no longer be accelerating, no longer increasing in speed, and he will then have balanced forces. Since the variables are always changing, drag will change with the most subtle changes in the skydiver's orientation either intentionally or unintentionally and the air resistance is constantly changing with increase in density, the forces will never be truly balanced. The effect of both forces will seesaw between one or the other being dominant. Terminal velocity is achieved when that process is minimal. It is of note that the effect of gravity itself is changing but over a skydive, the effect is negligible and may be ignored.
From my experience it would depend upon the initial velocity along with the mass of the object and how gravity will cause it to accelerate. Distance also plays a part in that the longer the object has to fall the faster it will fall. That is until it reaches terminal velocity or when the force of gravity equals the resistance force like air resistance.
terminal velocity
That is the object's terminal velocity.
terminal velocity
... I think you want to know about forces. At terminal velocity, the force of gravity is balanced by the air resistance, so no further acceleration occurs (balanced forces are the equivalent of an absence of force), which is why we call it *terminal* ("end value") velocity.
If its speed of fall is no longer changing, then its acceleration is zero. That tells you that the forces on it must be balanced, so the upward force of air resistance must be exactly equal to the downward force of gravity.
Yes
Fired ammunition from a firearm reaches a much higher initial velocity due to explosive propellant forces. In contrast, ammunition dropped from a high altitude reaches a terminal velocity where gravity pulling down is balanced by air resistance pushing up. The fired bullet maintains its higher velocity until slowed by air resistance and gravity, while dropped ammunition reaches a constant speed due to these opposing forces.
Terminal Velocity. This is the velocity at which the accelaration from Earth's gravity and the drag from air resistance reaches equillibrium.
The greatest velocity, achieved when the acceleration due to gravity is balanced by the aerodynamic deceleration, is called the terminal velocity.
Air resistance equals the pull of gravity, so essentially zero.
On any planet with an atmosphere, gravity is counteracted by the force of air friction with the object that is falling. This is known as terminal velocity - the point at which the forces of air resistance and gravity balance.
It's called terminal velocity and it's when the downward force of gravity equals the upward force of drag due to air resistance.
