* Equal in magnitude: The forces have the same strength.

* Opposite in direction: The forces act in directly opposing directions.

Here's why this creates no motion:

* Net force: When forces are balanced, the net force (the overall force acting on an object) is zero.

* 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 net force is zero, the object will remain in its current state of motion (or lack thereof).

Examples:

* A book sitting on a table: Gravity pulls the book down, but the table pushes back with an equal and opposite force, resulting in no motion.

* A tug-of-war with equal strength: Both teams pull with equal force in opposite directions, causing the rope to remain stationary.

Note: Even if the forces are equal in magnitude but not opposite in direction, they will not result in no motion. Instead, they will cause the object to move in the direction of the resultant force.
