well, we are moving at a constant speed(the earth's rotation) and everything else in the universe is as well because of the effects of gravity, so either nothing can be balanced because everything is moving, or plenty of things can be. I guess this depends on your definition of the word balance.
If a car is moving at a constant speed, it is in a state of balanced forces. The forces acting on the car are equal in magnitude and opposite in direction, resulting in no change in its speed or direction.
A balanced force will not cause a moving object to change its constant speed. It's an unbalanced force that would either speed up or slow down the moving object.
Balanced
If the forces acting on an object are balanced and the object is moving at a constant speed, the object will continue to move at that constant speed in a straight line. There will be no change in the object's velocity or direction of motion.
When a lorry is moving at a constant speed, the driving force from the engine is balanced by the resistive forces such as friction with the road, air resistance, and any incline or decline on the road. These balanced forces result in no net acceleration and allow the lorry to maintain a constant speed.
If an object is moving at a constant speed, the forces acting on it are balanced. This means that the forces pushing in one direction are equal to the forces pushing in the opposite direction, resulting in no change in the object's speed or direction.
Relative speed is the speed between two moving objects with no regards to a fixed reference. Speed is how fast something is moving with respect to an object.
Speed and velocity cannot be unequal for the same object. Speed tells you how quickly something is moving (as measured, for example, in meters per second) and velocity tells you how quickly something is moving and in what direction it is moving.
You're fishing for "balanced", but that still doesn't make the statement true.An object on a curved path can have constant speed even though the forceson it are not balanced.
Balanced forces will not change the velocity - speed and direction - of a moving object. the object will continue to move in the same way.
Balanced forces are equal in size and opposite in direction, causing an object to remain stationary or continue moving at a constant speed.
