Question

Quizplus · Accepted Answer

The equilibrium rule (ΣF = 0) applies to both objects or systems at rest and objects or systems in uniform motion in a straight line. This is because the rule states that the vector sum of all forces acting on an object must be equal to zero for the object to remain in a state of static equilibrium or constant velocity (i.e. no acceleration).
