Balanced forces acting on an object O Always change the object's motion.
O Sometimes change the object's motion.
O Never change the object's motion.
O Are not related to motion.

Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced

Explanation:

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 moving object continues to move at the same speed and in the same direction.
