must there be an unbalanced net force acting on any moving object?

Do you mean to move it or not move it?

to move it
Answered by bobpursley
An unbalanced force will accelerate the system. Balanced forces keep the object in constant motion, which is usually still, but it could be in motion at CONSTANT velocity and zero Acceleration.

The idea is NetForce=mass*netacceleration.
Acceleration is zero if the forces are balanced, or Net force is zero.
