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.

Is it possible for an object to not be in motion and still have forces acting on it?

Yes, the object can have equal forces acting in opposite directions: 5N ->[]<- 5N The object will have forces acting upon it, but will not move.


What are the similarities between balanced and unbalanced forces?

An object with balanced forces acting on it is still. An object with unbalanced forces acting on them moves at an non constant velocity. It is possible for an object to have balanced forces acting on it and yet move in a vacuum.

Will two or more forces acting at different angles be placed in the same quadrant or in the adjacent quadrant and still be in equilibrium?

if the two forces are acting in an opposit direction they can not be in equilibrum.but if they acting in thesame direction from different angles they can be in equilibrum.


What are the forces acting on sitting still?

The chair in pushing you up and the gravity pushing you down


What does the term balance mean?

If you add up all the forces acting on an object, they are balanced if they equal zero. (They cancel each other out). If the forces acting on a object are balanced, then the acceleration of that object is zero. It may still be moving, but it is not accelerating. An object that is not accelerating, (the sum of the forces acting on it is zero), is in equilibrium.


Is it possible for an object not to be in full motion and still have forces acting on it?

Yes hanging load. Its weight ie force due to gravity is acting downward. And the tension the rope is acting upward. Both the forces are acting on the load but as they are equal in magnitude and opposite in direction the resultant becomes zero.
