The term that best describes the movement produced by a force not applied through the center of mass is distortion. When a force is applied at a point away from the center of mass, it causes a change in shape or internal strain within the object rather than purely translating or rotating the entire object. This is because the force creates both translational movement and a rotational effect due to the moment arm created by the distance from the center of mass to the point of application.

In contrast, contraction generally refers to a decrease in size or volume in a uniform manner, which does not specifically address the effect of off-center forces. Translation refers to the movement of the center of mass itself without consideration of any rotational implications. Revolvement typically describes circular motion around a point or axis, which may occur if forces are applied at an angle, but does not capture the distortion aspect that results from off-center forces. Therefore, distortion is the most fitting term in this scenario to describe the impact of such forces.
