Lifting force acting upward
Weight of the object acting downward
Both are equal and opposite to each other
Drag and lift
That depends. If no forces act on the object, it will. If forces do act on the objects, such forces may change the object's velocity.
Forces that likely act upon a moving object include:frictiongravity
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.

Two - forces act in pairs. If object "A" acts on object "B", the object "B" will also act on object "A". In many practical situations, there may be additional forces involved. For example, if an object is at rest despite the fact that a force acts on it, then it is obvious that an additional force acts on the same object, and in the opposite direction. In such cases, there are at least four forces involved, since according to Newton's Third Law, there must be an opposite force for each of these two forces. (Note that in Newton's Third Law, the two forces act on DIFFERENT objects, so the two forces that hold an object in balance do not quality as a pair of forces according to Newton's Third Law.)

Because NOT all forces are equal and opposite. By Newton's Third Law, if object A attracts object B, then object B also attracts object A - with an equal but opposite force. But those forces act on DIFFERENT objects! The forces on object A, and on object B, may be unbalanced!Because NOT all forces are equal and opposite. By Newton's Third Law, if object A attracts object B, then object B also attracts object A - with an equal but opposite force. But those forces act on DIFFERENT objects!

If forces on an object are unbalanced, the object will accelerate or decelerate. If forces on an object are balanced, the object will stay still or keep moving with the same velocity.
That's it. A force is a push or pull on an object.
