Unbalanced forces always change the motion of an object. When multiple forces acting on an object do not cancel each other out, resulting in a net force, the object experiences an acceleration and its motion changes.
Balanced forces, on the other hand, do not change the motion of an object. When multiple forces acting on an object cancel each other out, resulting in a net force of zero, the object remains at rest or continues moving at a constant velocity.
Non-contact forces, such as gravity or magnetism, can cause a change in an object's motion without physical contact. For example, the gravitational force between the Earth and an object can change the object's motion without any direct contact between them.
Contact forces, like friction or push/pull forces, require physical contact between objects to change the motion. For instance, a person pushing a cart or a car's braking system applying friction to the wheels are examples of contact forces that can change the motion of an object.
