What else can I help you with?
Can you change the four forces in flight in any way?
Of course. That's exactly how you steer an airplane. -- Running the engines faster increases the thrust, which increases the airspeed. -- Increasing the airspeed or the angle of attack increases the lift, which makes the plane climb. -- Increasing the drag causes the airspeed to decrease, which causes the lift to decrease. -- Decreasing the airspeed or the angle of attack decreases the lift, which can be used to lose altitude. -- Using control surfaces to increase the lift of one wing while decreasing the lift of the other wing causes the airplane to bank toward the wing with less lift. -- Increasing the angle of attack during a bank causes the plane to be 'lifted' around a turn. -- Extending flaps increases both lift and drag. If thrust is maintained at the same time, the airplane loses airspeed but maintains altitude. Anything you want the airplane to do is accomplished by manipulating the four forces in flight.
When an object reaches terminal velocity and there is no net force what is the initial force that got it going to keep it in motion?
Gravity. The object starts at zero velocity, and gravity always pulls the same. Drag, however, increases when velocity increases. Terminal velocity is when gravity has accelerated the object to the speed where drag is the same as gravity.
Is called As the temperature increases the possible total humidity?
It stays the same
How does a plane fly if you are transporting a plant?
The same way it flies if you are not transporting a plant, by carefully balancing lift, weight, thrust and drag.
Does hoist mean the same thing as haul?
To hoist is to lift above or 'up' and haul would be to drag or carry in a lateral motion or forward.
Is it possible to have diffferent volumes yet same density?
Since Density=Volume/Mass, and the mass increases as the volume increases they will always have the same density no matter how big it is.
What is spoiler and flap and difference?
The simple answer is, flaps extend below and to the rear of the wing from the trailing edge and actually change the geometry of the wing, at the same time increasing drag and lift. Spoilers rise out of the top of the wing and kill lift without changing wing geometry, or adding too appreciably to drag.
Induced drag on a airplane?
In aerodynamics, lift-induced drag, induced drag, vortex drag, or sometimes drag due to lift, is a drag force that occurs whenever a moving object redirects the airflow coming at it. This drag force occurs in airplanes due to wings or a lifting body redirecting air to cause lift and also in cars with airfoil wings that redirect air to cause a downforce. With other parameters remaining the same, induced drag increases as the angle of attack increases.Source of induced drag:Lift is produced by the changing direction of the flow around a wing. The change of direction results in a change of velocity (even if there is no speed change, just as seen in uniform circular motion), which is an acceleration. To change the direction of the flow therefore requires that a force be applied to the fluid; lift is simply the reaction force of the fluid acting on the wing.When producing lift, air below the wing is generally at a higher than atmospheric pressure, while air above the wing is generally at a lower than atmospheric pressure. On a wing of finite span, this pressure difference causes air to flow from the lower surface wing root, around the wingtip, towards the upper surface wing root. This spanwise flow of air combines with chordwise flowing air, causing a change in speed and direction, which twists the airflow and produces vortices along the wing trailing edge. The vortices created are unstable, and they quickly combine to produce wingtip vortices.[2] The resulting vortices change the speed and direction of the airflow behind the trailing edge, deflecting it downwards, and thus inducing downwash behind the wing.Wingtip vortices also modify the airflow around a wing, compared to a wing of infinite span, reducing the effectiveness of the wing to generate lift, thus requiring a higher angle of attack to compensate, and tilting the total aerodynamic force rearwards. The angular deflection is small and has little effect on the lift. However, there is an increase in the drag equal to the product of the lift force and the angle through which it is deflected. Since the deflection is itself a function of the lift, the additional drag is proportional to the square of the lift.The total aerodynamic force is usually thought of as two components, lift and drag. By definition, the component of force parallel to the oncoming flow is called drag; and the component perpendicular to the oncoming flow is called lift.At practical angles of attack the lift greatly exceeds the drag. Unlike parasitic drag on an object (which is proportional to the square of the airspeed), for a given lift, induced drag on an airfoil is inversely proportional to the square of the airspeed. In straight and level flight of an aircraft, lift varies only slowly because it is approximately equal to the weight of the aircraft. Consequently in straight and level flight, the induced drag is inversely proportional to the square of the airspeed. At the speed for minimum drag, induced drag is equal to parasitic drag.

What is the name of the force that changes when the parachute opens?
The force that changes when the parachute opens is air resistance, also known as drag force. As the parachute opens, it increases the surface area exposed to the air, which increases the drag force acting on the parachute and slows down the descent of the object attached to the parachute.
What does the term drag mean in flight?
Drag is one of the four forces applicable to a flying aircraft: thrust, drag, lift and weight. Drag is the amount of resistance to forward motion caused by a solid body moving through a fluid (air is considered a fluid for the purpose of aerodynamics). The easiest way to feel the effect of drag is to stick one's arm out a car window while it's moving. First do it palm-down (horizontal), and then palm-forward (vertical). The force, known as "drag", pushing the arm backward increases substantially when the palm is vertical. That force is the same effect that an aircraft in flight experiences due to the frontal area of its airframe forcing its way through the air. The science of aerodynamics seeks to minimize the drag through streamlining and other design factors, since drag wastes fuel, but it is physically impossible to elimnate it.
What are the four things an airplane needs to fly?
The four "Forces" interacting with an airplane in flight is Lift, Thrust, Weight, and Drag. Weight is gravity pulling the plane down. Drag is the resistance of the air wanting to slow the plane down (two parts, parasitic drag(air resistance) and induced drag(drag created by the wings creation of lift.) Thrust is what makes the plane go forward, either a jet or rocket engine produce thrust, or a propeller produces thrust through an engine producing power (to keep it simple, this is essentially the same thing, just think of a force making the plane go forward). Finally, lift, this is created by the wing, low pressure above it, and a (relative) higher pressure below it.
