Here's why:
* Net Force: The overall force acting on an object is called the "net force." It's calculated by subtracting the forces opposing motion (like friction) from the forces causing motion (like pushing or pulling).
* Unbalanced Force: When the frictional force is greater, the net force is negative, meaning it acts in the opposite direction of the object's motion.
* Acceleration: According to Newton's Second Law of Motion, an unbalanced force causes an object to accelerate. In this case, the acceleration is in the opposite direction of the object's motion, meaning it slows down.
* Stopping: As the object slows down, the net force continues to act against its motion, eventually bringing it to a complete stop.
Example: Imagine pushing a heavy box across a rough floor. If you're not pushing hard enough to overcome the friction between the box and the floor, the box will slow down and stop even if you're still applying a force.
