* Forces are Balanced: When the applied force and kinetic friction are equal, they perfectly cancel each other out. This means there is no net force acting on the object.
* 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. Since the forces are balanced, the object continues moving at the speed it was already going.
Example:
Imagine you push a box across a rough floor. You apply a force to the box, but friction opposes your effort. If you push with just enough force to overcome the friction, the box will start moving. If you continue pushing with that exact same force, the box will move at a constant speed.
Important Note:
* Static friction is different from kinetic friction. Static friction acts on an object at rest, while kinetic friction acts on an object in motion.
* The object must already be in motion for the scenario described above to apply. If the object is at rest and the applied force equals the static friction, the object will remain at rest.
