Condition for Equilibrium

An object is in equilibrium if it satisfies Newtons' first law:

"An object at rest or moving in a straight line with constant velocity will remain in this state unless it is subjected to an unbalanced force"


Quite simply put, an object is in equilibrium if the sum of forces acting on it equals zero:

Newton's First Law

This equation is called the equation of equilibrium.
