* An object at rest: A book lying on a table is not moving, indicating that the forces acting on it (gravity pulling it down and the table's normal force pushing it up) are balanced.
* An object moving at a constant velocity: A car driving at a steady speed on a straight road is also in equilibrium. The forces of the engine pushing it forward are balanced by air resistance and friction acting against it.
* A seesaw balanced perfectly: When a seesaw is balanced, the weight of the people on each side and the distance from the pivot point are equal, resulting in no net force and a stable position.
It's important to note that zero resultant force does not necessarily mean the object is at rest. It can be moving at a constant velocity.
Here's a helpful way to visualize this: Imagine a tug-of-war. If both teams pull with the same force, the rope will not move. This is because the forces are balanced, and the resultant force is zero.
