* Balanced forces: When forces acting on an object are equal in magnitude and opposite in direction, they are balanced.
* Net force: The overall effect of all forces acting on an object is called the net force. When forces are balanced, the net force is zero.
* Newton's First Law: Newton's First Law of Motion states that an object at rest stays at rest, and an object in motion stays in motion at a constant velocity, unless acted upon by a net force.
In summary: Balanced forces cancel each other out, resulting in no net force. Without a net force, there is no change in motion.
