Balanced forces. When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces. If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: a stationary object stays still a moving object continues to move at the same speed and in the same direction
Unbalanced forces result in a net force and cause an object to move in the direction of the greater force. Finally, imagine the two friends pushing the box in the same direction. The combined forces cause the box to move in the direction they are both pushing.
