## Balanced forces: When a number of forces acting on a body do not cause any change in its state of rest or of uniform motion along a straight line then the forces are said to be balanced forces. In other words, a body is said to be underbalanced forced when the resulting force acting on the body is zero.The balanced forces: Cannot set any stationary body into motion. May change the shape and size of soft objects. Cannot change the speed/velocity of a moving body.Unbalanced forces:When the resultant of all the forces acting on a body is not zero, then forces are called unbalanced forces.Example: Game of tug of war: When the forces exerted by both the teams are equal, then the rope does not move. But, if the force applied by team A is greater than team B, then the rope, as well as members of the weaker team, i.e., B, will be pulled towards A. The unbalanced force can (a) Set a stationary body in motion.  Set a moving body at rest. Change the direction of motion.
