Q:

# What is the definition of "static equilibrium"?

A:

Static equilibrium is a form of equilibrium that occurs when an object is at rest. "Static" refers to the object being motionless while "equilibrium" refers to the object either having no net forces acting upon it or having all of its net forces balanced.

The state of an object relative to equilibrium is determined by the net forces acting upon it. Each force that acts on an object must be determined and quantified. Then, the vector forces can be added together. If they equal zero, then the object is in equilibrium. If the forces are zero and the object is at rest, then the object is in static equilibrium.

• A:

For a rigid body to be in static equilibrium, without total acceleration, two conditions must be met. First, the vector sum of all forces acting on it must be zero (translational equilibrium). Second, the sum off all torques due to any external force on any axis must be zero (rotational equilibrium).

The law of inertia states that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. The law of inertia is sometimes referred to as Newton's first law of motion.

Inertia is the tendency for an object to remain in motion or at rest unless it is acted upon by an outside force. In the field of physics, this concept is referred to as Newton's first law of motion.
