Dynamic equilibrium is characterized by which condition?

Dynamic equilibrium refers to a state where a body is in motion, yet the net forces acting upon it are balanced. This means that while the object may be moving, it does so at a constant velocity, indicating that there is no change in speed or direction. This condition of balanced forces ensures that the motion remains uniform, which is the hallmark of dynamic equilibrium.

In this scenario, the object is not accelerating because the forces acting on it—both internal and external—are equal and opposite, resulting in a net force of zero. This is different from a static scenario where the body is at rest or conditions where forces are unbalanced, leading to acceleration. Dynamic equilibrium therefore specifically describes the balance of forces during motion rather than at rest or in a state of acceleration.
