When a glider is hovering, the forces of gravity and lift are balanced. Gravity pulls the glider downwards, while lift generated by the wings opposes this force and keeps the glider suspended in the air. Because these forces are equal in magnitude and opposite in direction, the glider remains in a state of controlled hover.
No, a glider sailing across the sky at a steady speed and altitude is an example of a balanced force. The force of gravity pulling the glider down is balanced by the lift generated by the glider's wings, allowing it to maintain its steady speed and altitude.
The aerodynamic forces acting upon a glider in flight are lift and drag. Lift is generated by the airfoil shape of the wings and acts in an upward direction to support the weight of the glider. Drag opposes the motion of the glider and is caused by air resistance.
When a helicopter is hovering (aka "still") it has the force of gravity pushing "down" toward the Earth and the force of "lift" of the spinning rotor blade(s) pushing against the surrounding air. When the gravitational force is equal to the force of lift the helicopter hovers on the vertical axis.
If the net force is zero, then the forces are balanced. If the net force is not zero, then the forces are not balanced. You can have a balanced pair of forces, but not a pair of balanced forces.
You say that the two forces are in equilibrium.

Thrust generated by the glider's propulsion system, lift generated by the glider's wings, and drag acting in the opposite direction to the glider's motion.
The forces acting on a water glider are buoyancy, which is an upward force due to the displacement of water, and drag, which is a resistance force caused by the water's viscosity. Additionally, gravity acts downward on the water glider.
If the forces are balanced, then by definition the sum of the forces is zero.
Unbalanced forces is when the forces are 0N or more. Balanced forces are 0.
Balanced forces do not alter the motion of objects.
balanced
A balanced group of forces has the same effect as no force at all.
