What is the difference between balanced and unbalanced forces acting on a stationary object?
If the forces acting on an object are equal and opposite then they do not change the state of rest of the object or uniform motion along a straight line, but they can deform the object. These types of forces which do not cause any change in state of rest or of uniform motion along a straight line are called balanced forces. The resultant of balanced forces is always equal to zero (because the forces are equal and opposite). In tug of war, usually the weaker team is pulled by the other team, which is stronger. In this case, the forces are not equal and opposite i.e., they are not balanced and hence the weaker team is pulled by the stronger team. All of us know that when we stop pedalling a bicycle, the speed of the bicycle decreases due to the action of friction, which is the only force acting on the bicycle. Thus, if the forces acting on a body produce any change in state of rest or motion, then the forces are said to be unbalanced. An unbalanced force acting on an object changes its s
