Here's why:
* Equilibrium means a state of balance.
* Forces are pushes or pulls that can cause changes in motion (acceleration).
* If an object is in equilibrium, the forces acting on it are balanced, meaning they cancel each other out. This results in:
* No net force: The overall effect of the forces is zero.
* Constant velocity: The object either remains at rest or continues moving at a constant speed in a straight line.
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 balance each other out, resulting in the book remaining at rest.
