Here's why:
* Balanced forces: Balanced forces are equal in magnitude and opposite in direction. This means they cancel each other out.
* Net force: When forces are balanced, the net force acting on an object is zero.
* Newton's First Law: Newton's First Law of Motion 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.
Therefore, since balanced forces result in zero net force, they cannot cause a change in an object's state of rest or motion.
Example:
Imagine a book sitting on a table. The force of gravity is pulling the book downwards, while the table exerts an equal and opposite force upwards. These forces are balanced, resulting in zero net force. The book remains at rest.
