Here's why:
* Newton's First Law of Motion: 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: The net force is the overall force acting on an object. It's calculated by considering the direction and magnitude of all individual forces.
* Balanced Forces: When forces are balanced, their net force is zero. This means the forces cancel each other out, resulting in no change in the object's motion.
Example:
Imagine a book sitting on a table. Gravity is pulling the book down, and the table is pushing the book up with an equal and opposite force. These forces are balanced, so the book remains at rest.
