The forces that always change the motion of an object are **unbalanced forces**.
When the forces acting on an object are unbalanced, it results in a net force that causes the object to accelerate, change direction, or change its state of motion. In contrast, balanced forces do not change the motion of an object because they cancel each other out. Contact and non-contact forces can be either balanced or unbalanced, depending on the situation.
