Air resistance is not a downward force; it acts in the opposite direction of an object's travel. When a plane is in flight the forward force provided by the engines works against the backwards force of air resistance. If the engines are turned off the plane will begin to slow down. As a plane moves foreward the air moving over its wings creates an upward force called lift, which works against the pull of gravity.

What effect does resistance have on the acceleration of aircraft?
Resistance, or drag, acts opposite to the direction of motion and reduces the acceleration of aircraft. High resistance can slow down an aircraft and make it harder to increase speed or maintain acceleration. Pilots account for resistance when planning maneuvers and adjusting engine power to overcome drag.
Why several seconds after jumping from an aircraft a skydiver will be travelling at a constant speed?
After jumping from an aircraft, a skydiver falls due to gravity. As they fall, the force of gravity accelerates them until they reach what is called terminal velocity. At this point, the force of air resistance pushing up against them equals the force of gravity pulling them down, resulting in a balanced force and a constant speed.
Is air resistance a form of gravity?
No, air resistance is not a form of gravity. Air resistance is a type of friction that acts on objects moving through the air, slowing them down. Gravity, on the other hand, is the force of attraction between objects with mass.
Why aircraft and planes are not attracted by the force of gravity?
They certainly are. Just shut down the enginesand see what the aircraft does. In fact, they overcome gravity by generating a counteracting force called lift using the air motion over their wings. Gravity is still there, it's just that the net downward force has been reduced to zero.
When air resistance is greater than force of gravity what will be the effect of force?
When air resistance is greater than the force of gravity acting on an object, it will slow down the object's descent. This is because the air resistance force counteracts the force of gravity, reducing the acceleration of the object as it falls.

What is the role of gravity in landing an airplane?
Gravity is one of many forces that act upon an aircraft at ALL times. So naturally, gravity is what pulls the aircraft down when the pilot reduces the Thrust of the engines and the Lift of the wings.

Which direction does the parachutist go if gravity is greater than air resistance?
The parachutist will go down, of course. If gravity is greater than air resistance, then the parachutist would accelerate (his speed would increase). This would increase air resistance, up to the point where gravity and air resistance are in balance.
Is air resistance a form of gravity?
No, air resistance is not a form of gravity. Air resistance is a type of friction that acts on objects moving through the air, slowing them down. Gravity, on the other hand, is the force of attraction between objects with mass.

Is there a possibility that gravity doesnt exist?
No. Gravity exists. You have proof of this fact by the way you are held down when you walk instead of floating around.
What are the forces of flight?
The four forces that act on an airplane in Flight are Lift (upward generated by the wings), weight (Down generated by gravity, Thrust (forward generated by the engines), and drag (essentially backward generated by the resistance of the aircraft to the atmosphere).
What is gravity meter used in aircraft?
Aircraft are equipped with instruments that measure the G-forces. That doesn't mean it detects gravity. Instead, these measure the forces on the aircraft, where 1 G Down is the normal weight of the aircraft. This information is recorded and stored on the aircraft and Flight Data Recorder so mechanics can determine if the aircraft experienced a hard landing or other heavy load.
When air resistance is greater than force of gravity what will be the effect of force?
When air resistance is greater than the force of gravity acting on an object, it will slow down the object's descent. This is because the air resistance force counteracts the force of gravity, reducing the acceleration of the object as it falls.
In what direction does the force of air resistance act?
As far as I understand the direction of the force of air resistance acts in the opposite way to which you are going... In other words if a ball was thrown up at 20 m/s and the force of air resistance was 1m/s2 then for every second the ball goes up, it would slow down by 1m/s (assuming there was no gravity). The same applies if it was going down at 20 m/s it would slow down by 1m/s. When a parachutist opens a parachute, gravity tries to pull it down and air resistance keep it up.I think so.
On Earth which forces tend to slow an object down?
The main forces that tend to slow an object down on Earth are friction, air resistance, and gravity. Friction occurs when the object moves against a surface, air resistance is the drag force experienced as an object moves through the air, and gravity pulls the object downward.
