* Newton's First Law of Motion (Law of Inertia): This law states that an object at rest will stay at rest, and an object in motion will stay in motion at a constant velocity, unless acted upon by a net force.
* Net Force: Net force is the total force acting on an object. When forces are balanced (like a tug-of-war where neither side wins), the net force is zero.
* Constant Velocity: Constant velocity means the object is moving at a constant speed in a straight line. If the object is at rest, its velocity is 0.
In summary: If the net force is zero, the object will either stay at rest or continue moving at a constant velocity.
