In physics, what describes a situation in which an object experiences no net force acting upon it?

• A. Static equilibrium
• B. Dynamic equilibrium
• C. Inertia
• D. Rotational motion

Answer: (A)

A situation in which an object experiences no net force acting upon it is best described by static equilibrium. In static equilibrium, an object remains at rest, and all the forces acting on it are balanced, resulting in a net force of zero. This means that the sum of the forces in both the horizontal and vertical directions cancel each other out. In addition to static equilibrium, dynamic equilibrium is another state of no net force; however, it applies to objects in motion that continue to move at a constant velocity. This distinction is important, as static equilibrium specifically refers to objects that are not in motion at all. Inertia refers to the property of an object to resist changes to its state of motion, and it is not a state of equilibrium itself. Rotational motion involves an object moving around an axis and may include net forces acting upon it, so it does not fit the description of no net force adequately. Therefore, static equilibrium is the most accurate term for a situation where there is no net force acting on an object, especially when the object is at rest.
