To turn the force, muscle or constraint back on, click on Enable again.You can also enable and disable muscles and constraints via the Redo and Undo buttons in the Toolbar.

Note that if the center of mass happens to be a location embedded within the geometry of a body, you may need to adjust transparency or switch some Geometry display to wireframe.
