Here's why:
* Forces always come in pairs: Every action has an equal and opposite reaction (Newton's Third Law).
* Balanced forces cancel each other out: When two or more forces act on an object in opposite directions with equal magnitudes, they cancel each other out.
* No net force means no acceleration: Since the forces balance, there is no net force acting on the object. This means the object will either remain at rest or continue moving at a constant velocity.
Example:
Imagine a heavy box sitting on a table. The force of gravity is pulling the box down, but the table exerts an equal and opposite upward force, preventing the box from falling. These forces are balanced, so the box remains stationary.
