Answer:
No, because the sum of the forces equaling zero only implies that the object is not accelerating.
Step-by-step explanation:
When the sum of the forces acting on an object equals zero, this implies that the object is at equilibrium. And this could be either static or dynamic equilibrium.
A force is an agent that could change the state or direction of motion of an object. When the sum of all forces acting on an object equals zero, this implies all forces cancels out by resolution. Thus, the state of equilibrum is achieved. So this those not necessarily mean that the object is at rest, but could be in a dynamic equilibrium.
