1. Net force: The net force acting on the body must be zero. This means that the vector sum of all the forces acting on the body must be zero.
2. Balanced forces: The forces acting on the body must be balanced. This means that the forces must be equal in magnitude and opposite in direction.
Examples of moving bodies in equilibrium:
* A car moving at a constant speed on a straight road.
* A ball rolling down an inclined plane at a constant velocity.
* A person pushing a shopping cart at a constant speed.
* A book resting on a table.
In each of these examples, the net force acting on the body is zero and the forces are balanced. As a result, the bodies are in equilibrium and continue to move with constant velocity.
