Want this question answered?
If its velocity is constant, then the net force on it is zero, regardless of its mass or speed.
when the net force of an object is at zero, it is at rest. That means that the forces on it are balanced. when the net force is not zero, the forces are unbalanced.
If the vertical speed is constant, that means there is zero vertical acceleration. If the vertical acceleration is zero, that means the net vertical force on the object is zero. If the net vertical force on the object is zero, that means the downward force (weight) and upward force (air resistance) are equal.
Zero acceleration means no change in velocity and no force on the zero accelerating body.
Here is a hint: you can use Newton's Second Law for this one. The airplane can only go at a "constant velocity", i.e., zero acceleration, if the net force is also zero.
If the aircraft's altitude is constant, that means its vertical speed is zero. That indicates zero vertical component of any acceleration, which in turn implies that vertical force components are balanced. So you can say with assurance that the sum of (lift produced by the wings) PLUS (any vertical component of thrust due to a positive angle of attack) is equal to the airplane's weight (gravitational force on it).
Balanced force means two forces are acting on opposite sides of body and that body doesn't change its position.Nothing. Zero newtons. Zilch :L
Net force is the sum of all forces that act on an object. An unbalanced force means that net force is not equal to zero. If that is the case, the object will accelerate.Net force is the sum of all forces that act on an object. An unbalanced force means that net force is not equal to zero.

Absolutely. The key is to realize that a net force of zero on an object means only that it is not accelerating. This means that an object feeling zero net force can either be stationary or moving at constant speed in a straight line.
The net force will be zero only if the velocity is constant, which means acceleration is zero.

No type of force has a net force of zero. When two or more forces combine the net result may be zero
