Explanation:

Forces can be balanced or unbalanced.

When a number of forces acting on a body do not change its state of rest or uniform motion in a straight line , the forces are said to be balanced forces. For example : In the game of tug of war, two teams pull a rope in opposite directions. When the two teams exert equal and opposite forces on the rope, the rope remains steady and does not move in any direction. It appears as if no force is acting on the rope. Thus, the two forces acting on the rope in this case are balanced forces.

When a number of forces acting on a body change it's state of rest or uniform motion in a straight line, the forces are said to be unbalanced forces. For example, if we push a toy car towards east, it moves towards east. If it is pushed towards west, it moves towards west. This unbalanced force produces motion.

Hope I helped!
