What is the term used to describe the rotational tendency when a force is not applied through the center of resistance?

The term that describes the rotational tendency when a force is not applied through the center of resistance is torque. Torque is a measure of the rotational force that results from a force applied at a distance from a pivot point or axis of rotation. When a force acts at a distance from the center of resistance, it creates a moment that can cause the object to rotate around that axis. This relationship between the magnitude of the force, the distance from the point of application to the center of resistance, and the angle at which the force is applied all contribute to the resulting torque.

In the context of orthodontics, understanding torque is critical, as it helps clinicians predict how teeth will move when forces are applied, especially in achieving desired rotational movements. Recognizing how force is applied relative to the center of resistance allows orthodontists to create effective treatment plans for tooth alignment.
