example of balance force and unbalance force?

Sagot :

Balanced forces
             - are forces having opposite directions and same magnitude that acts on an object, making the object unable to move to either directions, making the object stay at rest. Balanced forces have no net force. The sum of all the forces in balanced forces is equal to 0.
Example:
               A boy pulling a rope with 10 units of force. A girl pulling the other end of the same rope in the opposite direction of the boy with 10 units of force. 

Unbalanced forces
         - are forces responsible in the motion of objects. Unbalanced forces result into a net force. The sum of all the forces of unbalanced forces is never equal to 0.

Example:
              A boy pulling a rope with 10 units of force. A girl pulling the other end of the same rope in the opposite direction of the boy with 5 units of force.
