Balanced & Unbalanced Forces Video For Kids | 3rd, 4th
Unbalanced forces change the motion of an object. This happens in two ways. If an object is at rest and an unbalanced force pushes or pulls the object, it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion. A game of tug-of-war is a great way to illustrate an unbalanced force.

Echocardiographic Definition and Surgical Decision …
left ventricles (balanced) or unequally over the ventricles (unbalanced). An important determinant of whether an AVSD can be repaired is the relative size of the right and left valve after division of the common AV valve, that is the degree of balance between the two valves. The AVVI was introduced by Cohen et al as an echocardiographic

Practical Roll Techniques
The resultant unbalanced forces are detrimental to the rolls involved and to the associated machine elements. In most rolls, balance exists at some points along the roll face and not at others. If the roll is rigid and short, the unbalanced points will be carried by adjacent balanced or counterbalanced points and smooth operation will result.

Balanced forces obey the balanced force law : When an object's net force = 0, it continues to move at the same speed (and in the same direction ). This car's speed stays the same because the net force = 0 (force forwards = force backwards) If an object's net force ≠ 0, we say its forces are unbalanced. When an object's net force ≠ 0, its ...
