What else can I help you with?
What is the correct term for the greatest velocity an object can reach before air resistance knocks it down?
The term you're looking for is "terminal velocity," which is the maximum velocity an object can reach as it falls through a fluid like air, balancing the force of gravity with the force of air resistance.
Why can an object falling in an vacuum never reach terminal velocity?
In a vacuum, there is no air resistance to oppose the motion of the falling object, so there is no force acting to limit its acceleration and reach terminal velocity. As a result, the object will continue to accelerate indefinitely as it falls through the vacuum.
What is the maximum speed an object can reach in free fall?
That would be the escape velocity of Earth, about 11.2 km/sec. I am assuming that the object falls from far, far away, and that air resistance is negligible.That would be the escape velocity of Earth, about 11.2 km/sec.

How does air resistance change the longer an object falls?
The force the air resistance do against the object is proportional to it speed (F=C*v^2, usually, where C is a constant and v is the speed). So, the higher the speed, the higher the force. If an object is falling, the gravity is probably responsible for it. When the force of the gravity is equivalent to the force made by the air resistance, the speed of the object remains constant. To answer your question directly: without air resistance, the graphic position X time would be parabolic. With air resistance, it looks like an decaying exponential.
When does an object reach its terminal velocity?
An object reaches its terminal velocity when the force of gravity pulling it down is equal to the air resistance pushing it up. At this point, the object stops accelerating and falls at a constant speed without gaining more velocity.

Is terminal velocity the highest velocity that a falling object will reach?
Yes, terminal velocity is the highest velocity that a falling object will reach when the force of air resistance equals the force of gravity acting on the object, causing it to no longer accelerate. At terminal velocity, the object falls at a constant speed without further acceleration.
How does air resistance affect the acceleration of falling objects?
As a falling object accelerates through air, its speed increases and air resistance increases. While gravity pulls the object down, we find that air resistance is trying to limit the object's speed. Air resistance reduces the acceleration of a falling object. It would accelerate faster if it was falling in a vacuum.
What slows an object in free fall?
Air resistance is what slows an object in free fall. As an object falls, it pushes through air molecules, causing air resistance to counteract the force of gravity pulling it down. This resistance increases with the speed of the object, eventually causing it to reach a terminal velocity where the forces balance out and it no longer accelerates.
Why does an object with a large surface area reach terminal velocity before an object with a small surface area?
An object with a large surface area experiences more air resistance, which increases as the object accelerates. This causes the object to reach terminal velocity quicker compared to an object with a smaller surface area, which experiences less air resistance and takes longer to reach terminal velocity.
Why falling objects don not move forward with a speed of 17700 mph?
And what makes you think an object would fall, or should fall, precisely at such a speed? How do you get that number? - Anyway, that's not the way our Universe works. Without air resistance, an object that falls downward falls faster and faster - its speed increasing by 9.8 meter/second every second. With air resistance, a falling object will eventually reach a speed at which friction (air resistance) balances the downward force of gravity. This speed is different for different objects.
How can you measure when an object has reached terminal velocity?
Terminal velocity is reached when the forces of gravity and air resistance acting on an object are equal, causing the object to no longer accelerate. To measure when an object has reached terminal velocity, you can observe that the object falls at a constant speed without speeding up. This can be done by measuring the object's velocity as it falls and noting when it remains constant.
What opposing forces act on an object falling freely through the atmosphere?
The forces that affect the rate of a falling object are Gravity and Air Resistance. Gravity affects the speed and the velocity of the object by speeding it up as it falls closer to the earth, and Air resistance works against the object pushing against it.
