Here's why:
* Forces: Forces are pushes or pulls that can change an object's motion.
* Balanced Forces: When forces are balanced, they cancel each other out. This means the net force (the overall effect of all the forces) is zero.
* Equilibrium: In equilibrium, an object at rest will remain at rest, and an object in motion will continue moving at a constant velocity.
Example:
Imagine a book resting on a table. Gravity pulls the book down, but the table pushes back with an equal and opposite force. These forces are balanced, so the book remains at rest.
