What is the definition of unbalance force?

Answer 1

Unbalanced force is simply where forces are unbalanced.

Unbalanced forces are where the net force of an object is not equal to zero leading to acceleration or deceleration. If friction is neglected on a car moving at 50kmh it's net force is equal to zero as it is moving at a constant speed without accelerating or decelerating

Answer 2

An unbalance force is one that is not opposed by an equal and opposite

force operating directly against the force intended to cause a change in

the object's state of motion or rest. Consider this little illustration:

Object, O is at rest and subjected to a force from the left as shown:

Let ====> represent the force to change the object's state of motion or

rest on object. O

This unopposed (unbalanced) force will cause the object to move to the

right. ====> O

Let O <==> O <========,

the larger force coming from the right is unbalance by the one from the

left. Thus, the object will move toward the left.

The picture is more complicated that I can illustrate here because an

opposing force my be impinging on the object from an angle. Overall, it is

the "net" unbalanced force that will cause the object to move or change

its state of motion.

Answer 3

An unbalance force is one that is not opposed by an equal and opposite force operating directly against the force intended to cause a change in the object's state of motion or rest.

Answer 4

An unbalanced force is a force that results in a change in an object's motion. When the forces acting on an object are not equal in magnitude and opposite in direction, there is an unbalanced force causing the object to accelerate.

Answer 5

That simply means that the sum (vector sum) of all forces acting on an object is not equal to zero.

Answer 6

A force that is not balanced

Answer 7

A force is a push, a pull, and a twist
